One week until Electronica!

This year one of the largest electronics trade fairs in the world is taking place in Munich, Germany.

Cyclops’s founder has been attending Electronica since it first began, so the convention has always been a highlight of our calendar. We have met many clients and partners through the connections provided to us by Electronica.

The convention is focusing on the promotion of sustainability this year. Bringing the industry together in one location with the aim of “Driving Sustainable Progress”, Electronica hopes to show the role the world that electronics will help, not hinder, sustainability.

The previous Electronica in 2020 was purely virtual, but having hundreds of exhibitors back in Messe München, spread over 13 halls, will be an event to remember.

 In 2018 there were more than 81,000 visitors to the trade fair from 101 countries. 3,124 exhibitors attended the event, we’re hoping for an even more enthusiastic turnout this time around.

In 2021 there was a 9.8% increase in industry revenue from the previous year, at €200 billion, which is astounding progress during the pandemic.

Electronica will have a supporting program full of knowledge and professional talks. During conferences experts will analyse market activity.

The convention has been held every other year since 1964, and has continually grown and evolved over the years.

In the final week leading up to the trade fair, we want to organise meetings with all our clients who are also attending. Whether you are a returning or new customer, we want to show you what Cyclops can do for you.

We have the expertise and drive to go the extra mile for you. Whether you are looking to buy or sell, Cyclops has a solution for you.

Whether you are a returning customer or are completely new to Cyclops, we want to meet you. If you are attending Electronica you can book an appointment with our staff to discuss your needs at Eventbrite now.

Price of semiconductor equipment increasing

The price of chip manufacturing is increasing. From skyrocketing raw material prices to continual high demand for semiconductors, it/ is an expensive business right now. Semiconductor manufacturing prices are also on the rise.

Global manufacturers are announcing price hikes to combat the expected rise in inflation, passing the cost onto the customer.

Is reshoring reassuring?

Aside from the supply chain issues and raw material shortages, the drive for reshoring will drive up the cost and demand of semiconductor manufacturing equipment.

In both the US and the UK, new legislation is in the works to provide funding for the electronics industry. It comes alongside a push to reduce reliance on semiconductors sourced from Asia, especially powerhouses like Taiwan and China.

The Chips Acts

In the west’s new legislation, funding and incentives are offered to domestic and international companies looking to build fabs. One such company was TSMC itself, which was rumoured last year to be opening a branch in Germany.

While these grants and investments will go some way to covering the cost of new semiconductor manufacturing equipment, it will only be part of the massive price manufacturers pay.

A new challenger

This may not be the only international development affecting the price increases of semiconductor equipment. New competitors are throwing their proverbial hat in the semiconductor manufacturing ring. One of the countries that is beginning to manufacture more is India.

As the US and Europe are already heavy-hitters in the industry, India will have to make hefty investments into manufacturing. Bulk-buying machinery and technology for facilities will mean more demand, and distributors putting on a bigger price tag. Taiwanese manufacturer Foxconn announced it would be setting up a fab in the country.

Other costs

The cost of making the semiconductor manufacturing equipment also comes into play. As companies are persuaded to move west, the cost of their manufacturing will increase. Many companies based in the east have access to cheaper labour but European and US labour costs will be higher.

Outside of Asia, in areas that are reshoring, there will also be the struggle of finding highly qualified employees. Since there was no need for skilled individuals when there were no fabs, there is a gap in the industry. It will take some time to catch up with industry standards of education.

Kit up

As the chip shortages continue, there’s no guarantee when the cost increase of semiconductor manufacturing equipment might slow down. As with all things, we’ll have to wait and see.

PCB assembly

Circuit boards, Assemble!

We’re not quite the Avengers, but we do know a thing or two about assembly.

As an electronic component supplier, Cyclops works to get customers the electronic components they are looking for. Further down the line, manufacturers construct the printed circuit boards (PCBs) featuring our sourced components.

The assembly of a PCB is a delicate and painstaking process. Just one millimetre of misalignment could mean failure of the whole board. Here’s a brief run-down of what’s involved.

Applying solder paste

The first step in the assembly of a PCB is applying a layer of solder paste. The PCB is overlayed with a stencil, and the solder paste is applied over this. The right amount must be used, as this is spread evenly across the openings on the board.

After the stencil and applicator are removed the PCB will be left and moves on to stage two.

Pick and place

The automated placement of the surface mount devices (SMDs) is done by a ‘pick and place’ robot.

The pick and place machine will have a file containing all of the coordinates for the PCB’s components. Every component will have its X and Y coordinates and its orientation included. This information enables the robot to place components on the layer of solder on top of the PCB accurately.

Reflow soldering

From the pick and place machine, the PCBs are directly transferred to a 250⁰ oven, where the solder paste melts and secures the electronic components to the board. Immediately after this, the boards are moved into a cooler to harden the solder joints.

The alternative to reflow soldering is a process called wave soldering. Much like the name suggests, in this method a ‘wave’ of solder moves across the board instead of being pasted on to start with.

Inspection

Once the reflow solder is cooled the PCBs are checked. If anything became misaligned or any solder or components are in the incorrect position, this inspection mitigates the risk to the customer.

When it comes to inspection methods, there are a few options:

Manual inspection – The most basic form of inspection, done with the naked eye. Better for PCBs with through hole technology (THT) and larger components.

Optical inspection – Using high resolution cameras, machines can check large batches of boards for accuracy at a high speed.

X-ray inspection – Give technicians the ability to check inner layers of multi-layer PCBs. This inspection method is usually reserved for more complex boards.

What a Marvel!

Thermal management of semiconductors

Too hot to handle

Every electronic device or circuit will create heat when in use, and it’s important to manage this. If the thermal output isn’t carefully controlled it can end up damaging, or even destroying the circuit.

This is especially an issue in the area of power electronics, where circuits reaching high temperatures are inevitable.

Passive thermal dissipation can only do so much. Devices called heat sinks can be used in circuits to safely and efficiently dissipate the heat created. Fans or air and water-cooling devices can be used also.

Feelin’ hot, hot, hot!

Using thermistors can help reliably track the temperature limits of components. When used correctly, they can also trigger a cooling device at a designated temperature.

When it comes to choosing a thermistor, there is the choice between negative temperature coefficient (NTC) thermistors, and positive temperature coefficient (PTC) thermistors. PTCs are the most suitable, as their resistance will increase as the temperature does.

Thermistors can be connected in a series and can monitor several potential hotspots simultaneously. If a specified temperature is reached or exceeded, the circuit will switch into a high ohmic state.

I got the power!

Power electronics can suffer from mechanical damage and different components can have different coefficients of thermal expansion (CTE). If components like these are stacked and expand at different rates, the solder joints can get damaged.

After enough temperature changes, caused by thermal cycling, degradation will start to be visible.

If there are only short bursts of power applied, there will be more thermal damage in the wiring. The wire will expand and contract with the temperature, and since both ends of the wire are fixed in place this will eventually cause them to detach.

The heat is on

So we’ve established that temperature changes can cause some pretty severe damage, but how do we stop them? Well, you can’t really, but you can use components like heat sinks to dissipate the heat more efficiently.

Heat sinks work by effectively taking the heat away from critical components and spreading it across a larger surface area. They usually contain lots of strips of metal, called fins, which help to distribute heat. Some even utilise a fan or cooling fluid to cool the components at a quicker speed.

The disadvantage to using heat sinks is the amount of space they need. If you are trying to keep a circuit small, adding a heat sink will compromise this. To reduce the risk of this as much as possible,  identify the temperature limits of devices and choose the size of heat sink accordingly.

Most designers should provide the temperature limits of devices, so hopefully matching them to a heat sink will be easy.

Hot ‘n’ cold

When putting together a circuit or device, the temperature limits should be identified, and measures put in place to avoid unnecessary damage.

Heat sinks may not be the best choice for everyone, so make sure to examine your options carefully. There are also options like fan or liquid-based cooling systems.

Cyclops Electronics can supply both electronic components and the heat sinks to protect them. If you’re looking for everyday or obsolete components, contact Cyclops today and see what we can do for you.

Superconductivity

Superconductivity is the absence of any electrical resistance of some materials at specific low temperatures. As a starting point this is pretty vague, so let’s define it a bit more clearly.

The benefits of a superconductor is that it can sustain a current indefinitely, without the drawback of resistance. This means it won’t lose any energy over time, as long as the material stays in a superconducting state.

Uses

Superconductors are used in some magnetic devices, like medical imaging devices and energy-storage systems. They can also be used in motors, generators and transformers, or devices for measuring magnetic fields, voltages, or currents.

The low power dissipation, high-speed operation and high sensitivity make superconductors an attractive prospect. However, due to the cool temperatures required to keep the material in a superconducting state, it’s not widely utilised.

Effect of temperature

The most common temperature that triggers the superconductor effect is -253⁰C (20 Kelvin). High-temperature superconductors also exist and have a transition temperature of around -193⁰C (80K).

This so-called transition temperature is not easily achieved under normal circumstances, hence why you don’t hear about superconductors that often. Currently superconductors are mostly used in industrial applications so they can be kept at low temperatures more efficiently.

Type I and Type II

You can sort superconductors into two types depending on their magnetic behaviour. Type I materials are only in their superconducting state until a threshold is reached, at which point they will no longer be superconducting.

Type II superconducting materials have two critical magnetic fields. After the first critical magnetic field the superconductor moves into a ‘mixed state’. In this state some of the superconductor reverts to normal conducting behaviour, which takes pressure off another part of the material and allows it to continue as a superconductor. At some point the material will hit its second critical magnetic field, and the entire material will revert to regular conducting behaviour.

This mixed state of type II superconductors has made it possible to develop magnets for use in high magnetic fields, like in particle accelerators.

The materials

There are 27 metal-based elements that are superconductors in their usual crystallographic forms at low temperatures and low atmospheric pressure. These include well-known materials such as aluminium, tin and lead.

Another 11 elements that are metals, semimetals or semiconductors can also be superconductors at low temperatures but high atmospheric pressure. There are also elements that are not usually superconducting, but can be made to be if prepared in a highly disordered form.

What is Raspberry Pi

If you work in the electronics industry you might have heard of the Raspberry Pi circuit board. This device is a single-board computer, originally made by the UK-based Raspberry Pi Foundation.

Raspberry Pi boards use Linux and have a set of general purpose input/output (GPIO) pins. This means the user can attach electronic components and create different circuit boards.

History

The Raspberry Pi Foundation is a charity focused on teaching computing, and aims to make the subject simple and fun. To this end, The Raspberry Pi single-board computer was released to aid students and teachers in learning electronics affordably.

The original Pi was released in 2012 and quickly became popular, not only for education but in multiple industries. Since it uses a Linux-based OS it was also used by programmers and developers.

Raspberry Pi 1 Model B had a single-core 700MHz CPU, an ARM1176JZF-S processor, a VideoCore IV GPU, and had 512MB of RAM, and sold at lower than $35 on its release in April 2012.

Components

Since 2012 there have been several generations of Raspberry Pi. The latest model can have up to 8GB of RAM and a 64-Bit quad-core processor. Additionally, the Raspberry Pi 4 has two micro-HDMI ports that support 4K at 60GHz displays, a MIPI DSI (display serial interface) display port, MIPI CSI (camera serial interface) camera port, 4 pole stereo output and composite video port.

Potential Uses

One of the attractions of the Raspberry Pi device is the 40-pin GPIO header and four USB ports. This gives the opportunity for users to connect and build various types of circuits using external components.

Pi comes with an official operating system named Raspbian OS. The OS has a GUI that can be used for browsing, programming, games, and other applications.

Batteries or solar panels can be connected to power the circuit, which at peak would only require 7.6W of power. A power supply can also be connected via the USB port. One such power supply is provided by the Raspberry Pi Foundation itself at 5.1V.

Microphones and buzzers can be connected via the GPIO pins to create simple circuits. Motion sensors, servos and more, can also be attached in any combination.

There are numerous entertaining projects to undertake for those interested, and for the people who need it there is plenty of inspiration available online.

Pi’nally…

Cyclops Electronics can supply Raspberry Pi products, customers need only get in touch! For this, and all your other electronic component needs, contact Cyclops today.

RoHS, REACH, and dangerous substance legislation

RoHS and REACH are two pieces of legislation referring to the control of dangerous substances and chemicals. Companies manufacturing and distributing electronic equipment in Europe must comply to be able to trade.

RoHS

The Restriction of Hazardous Substances (RoHS) Directive came into force in 2004. With an aim to mitigate the effect of dangerous substances on customers, the Directive restricts the concentration of 10 substances used in Electrical and Electronic Equipment (EEE).

Acceptable levels of restricted substances in a single material are generally less than 0.1% or 1000 parts per million (ppm). For the chemical Cadmium, however, levels must be no more than 0.01% or 100ppm.

Companies must provide proof that they comply with the regulations by way of documentation. This includes a Declaration of Conformity, a record of the assessment procedure for conformity, and any other control documentation.

Since its release in ’04, there have been 3 iterations, with the latest being introduced in July of 2019. RoHS 3.0 introduces 11 new category products and four new substances.

The materials listed include products that could be harmful to not only human health, but the environment too. As such, non-compliance carries with it the potential for a heavy fine.

RoHS certification takes place in several steps:

  1. Extraction testing of the components takes place to determine the value of the RoHS substances contained.
  2. On-site manufacturing processes are inspected to ensure RoHS compliance at the facility.
  3. Review all relevant documentation, including the BOM (Bill of Materials), assembly drawings, and test reports from suppliers.
  4. Following this, if all is in order a RoHS Certificate of Compliance is issued.

REACH

REACH stands for the Registration, Evaluation, Authorisation and Restriction of Chemicals. It was introduced a few years on from RoHS, in 2006.

The scope of REACH is more inclusive than RoHS. It encompasses almost all products manufactured, imported, or sold in the EU or UK.

REACH revolves more around Substances of Very High Concern (SVCH), which includes those considered carcinogenic, mutagenic or toxic for reproduction.

Manufacturers and importers need to register the quantities of substances produced every year. Companies need to safely manage and publicise the risks associated with the substances. They’re also responsible for tracking and managing which substances are being used, and produce safety guidelines for each.

Recent changes

Due to events like Brexit in the UK, RoHS and REACH regulations became transplanted into UK law. Since many substances are imported between mainland Europe and the UK, the legislation in both remained very similar.

As part of the European Union (Withdrawal) Act 2018, REACH was copied into UK legislation, becoming UK REACH in 2021. Although the difference is seemingly in name alone, the two REACHs operate separately, and manufacturers need to comply with both.

REACH for the stars!

Cyclops can supply products that are RoHS and REACH compliant and can provide this information to our customers. This means Cyclops customers can guarantee if they want RoHS compliant parts, they will receive them. So contact Cyclops Electronics today!

Could conductive ink replace conventional circuitry?

It seems like the stuff of dreams, having a pen or a paintbrush that could conduct electricity. Well, those dreams are very real, readily available to buy online, and at a relatively cheap rate, too.

Conductive ink pens and conductive paint that can be used with a pen, paintbrush, or a printer is a reality, and is already being put to work.

What is it?

Conductive ink and conductive paint are liquid materials mixed with nanoparticles of a conducting material like silver or graphite. The paint and ink are technically slightly different, in that the paint sits on the surface of a substrate, while the ink would sink into a substrate it was applied to, like regular ink on paper.

Although the metals are usually in a solid state at room temperature, if it’s in a nanoparticle form it can be mixed with a liquid. When the liquid is spread and begins to dry, the nanoparticles and electrons within them begin to form conductive chains that the current is then able to travel through.

The inks used normally work at 12V, and can be transparent which means it would be a good choice for companies to integrate it invisibly into their graphics.

Uses

One notable way silver-infused ink is currently used is to print Radio Frequency Identification (RFID) tags in tickets.

Another common place to find conductive paint or ink is in the rear windscreen of cars. The resistive traces applied to windscreens to help defrost them contain conductive paint. Traces printed on the window can also serve as a radio antenna in more recently manufactured cars.

Conductive inks and paints were originally intended to be used for e-textiles and wearables. The potential for clothes that could detect temperature and heart rate, among other features, is an area receiving considerable investment.

Problems

When compared to conventional circuity and conductors, conductive inks and paints will never be able to emulate the strength of conductivity. In a way, it would be unfair to pit the two against each other, like putting boxers from vastly different weight classes in a ring together.

The reliability and connectivity of traditional conductors is much higher so is preferred for regularly used products, however conductive inks and paints would be utilised in areas that traditional means could not. So, as much as these factors are disadvantages they would be irrelevant when it comes to the product.

Layers of the ink or paint may not always be thick enough to have any conductive strength at all, and it could take several layers of it to properly form a current-conducting pathway. Additionally, the user is relying on the nanoparticles in the liquid to align correctly for conduction. The material would work only for smaller direct voltages too, probably up to around 12V.

Silver is a material that has a higher cost than other conductors like graphite, and could make the price of some paints unreasonable for some customers. The low cost alternative is graphite, but this also has a higher resistivity than metals like silver.

The future

As far as development goes, nanoparticle paint is still in its infancy. Its uses are limited and occasionally unreliable, so although it has cornered a niche conductive market it’s unlikely we’ll see it permeating the sector for a while.

Component Shortage Electric Vehicles Electronic Components Semiconductor Supply Chain Technology

Chip shortage impact on electric car sales

Many renowned car companies have, by this point, tested the waters of the electric vehicle (EV) market. However, thanks to the roaring success of electric car sales last year, and governmental and environmental incentives, the EV market is about to shift up a gear.

Global shortage

The vehicle market was not able to avoid the semiconductor shortage that has been prolific for the past few years. Safety features, connectivity and a car’s onboard touchscreen all require chips to function.

This, combined with the work-from-home evolution kick-started by the pandemic, meant that car sales decreased, and manufacturers slowed down production. New car sales were down 15% year-on-year in 2020, and the chips freed up by this ended up being redirected to other profiting sectors.

Even without the demand from the automotive industry, it has not been plain sailing for chipmakers, who not only had to contend with factory closures due to COVID-19, but also several natural disasters and factory fires, and a heightened demand from other sectors. Needless to say, the industry is still catching up two years later.

The automaker market

Despite new car sales having an overall decline in 2020, EV sales had about 40% growth, and in 2021 there were 6.6 million electric cars sold. This was more than triple of their market share from two years previously, going from 2.5% of all car sales in 2019 to 9% last year.

Part of the reason why EV sales were able to continue was due to the use of power electronics in the vehicles. While there is a dramatic shortage of semiconductors and microelectronics (MCUs), the shortage has not affected the power electronics market to the same extent. That is not to say that an EV doesn’t need chips. On the contrary, a single car needs around 2,000 of them.

It begs the question, how many EVs could have been sold if there weren’t any manufacturing constraints. Larger companies with more buying power would have been able to continue business, albeit at an elevated cost, while smaller companies may have been unable to sustain production.

Bestsellers

The growth of the EV business in China is far ahead of any other region, with more EVs being sold there in 2021 than in the entire world in 2020. The US also had a huge increase in sales in 2021, doubling their market share to 4.5% and selling more than 500,000 EVs.

In Europe last year 17% of car sales in 2021 were electric with Norway, Sweden, the Netherlands and Germany being the top customers. Between them, China, the US and Europe account for 90% of EV sales

Predictions and incentives

Several governments have set targets to incentivise the purchase of electric cars, and to cut down on CO² emissions caused by traditional combustion engines. Many of these authorities have given themselves ambitiously little time to achieve this, too.

Biden announced last year that the US would be aiming for half of all car sales to be electric by 2030, and half a million new EV charging points would be installed alongside this. The EU commission was similarly bold, proposing that the CO² emission standard for new cars should be zero by 2035, a 55% drop from the levels in 2021.

Companies are also setting EV targets and investing in new electronic models. Some manufacturers are setting targets as high as 50% of their production being electric within the next decade, while others have allotted $35 billion in investment in their pursuit of EV sales.

Possible pitfalls

Aside from the obvious issues there have been with semiconductor production and sourcing, there are also other factors that may make the future of EVs uncertain. One of the essential components of an electric car is its battery, and the materials that are used are increasing in price.

Lithium, used in the production of lithium-ion EV batteries, appears to be in short supply, while nickel, graphite and cobalt prices are also creeping up. However, research is underway for potential replacements for these, which may help for both supply times and the associated costs.

The shortages are affecting everyone, but thankfully Cyclops is here to take some pressure off. No matter what electronic components you are looking for, the team at Cyclops are ready to help.

The History of Transistors

Transistors are a vital, ubiquitous electronic component. Their main function is to switch or amplify the electrical current in a circuit, and a modern device like a smartphone can contain between 2 and 4 billion transistors.

So that’s some modern context, but have you ever wondered when the transistor was invented? Or what it looked like?

Pre-transistor technology

Going way back to when Ohm’s Law was first discovered in 1820s, people had been aware of circuits and the flow of current. As an extension of this, there was an awareness of conductors.

Following on from this, semiconductors accompanied the birth of the AC-DC (alternating current – direct current) conversion device, the rectifier, in 1874.

Two patents were filed in the 20s and 30s for devices that would have been transistors if they had ever reached past the theoretical stage. In 1925 Julius Lilienfeld of Austria-Hungary filed a patent, but did not end up releasing any papers regarding his research on the field-effect transistor, and so his discoveries were ignored.

Again, in 1934 German physicist Oskar Heil’s patent was on a device that, by applying an electrical field, could control the current in a circuit. With only theoretical ideas, this also did not become the first field effect transistor.

The invention of transistors

The official invention of a working transistor was in 1947, and the device was announced a year later in 1948. The inventors were three physicists working at Bell Telephone Laboratories in New Jersey, USA. William Shockley, John Bardeen and Walter Brattain were part of a semiconductor research subgroup working out of the labs.

One of the first attempts they made at a transistor was Shockley’s semiconductor triode, which was made up of three electrodes, an emitter, a collector and a large low-resistance contact placed on a block of germanium. However, the semiconductor surface trapped electrons, which blocked the main channel from the effect of the external field.

Despite this initial idea not working out, the issue was solved in 1946. After spending some time looking into three-layer structures featuring a reversed and forward-biased junction, they returned to their project on field-effect devices in a year later in 1947. At the end of that year, they found that with two very close contact junctions, with one forward biased and one reverse biased, there would be a slight gain.

The first working transistor featured a strip of gold over a triangle of plastic, finely cut with a razor at the tip to create two contact points with a hair’s breadth between them and placed on top of a block of germanium.

The device was announced in June of 1948 as the transistor – a mix of the words ‘transconductance’, ‘transfer’ and ‘varistor’.

The French connection

At the same time over the water in France, two German physicists working for Compagnie des Freins et Signaux were at a similar stage in the development of a point contact device, which they went on to call the ‘transistron’ when it was released.  

Herbert Mataré and Heinrich Welker released the transistron a few months after the Bell Labs transistor was announced but was engineered completely without influence by their American counterpart due to the secrecy around the Bell project.

Where we are now

The first germanium transistors were used in computers as a replacement for their predecessor vacuum tubes, and transistor car radios were produced all within only six years of its invention.

The first transistor was made with germanium, but since the material can’t withstand heats of more than 180˚F (82.2˚C), in 1954 Bell Labs switched to silicon. Later that year Texas Instruments began mass-producing silicon transistors.

First silicon transistor made in 1954 by Bell Labs, then Texas Instruments made first commercial mass produced silicon transistor the same year. Six years later in 1960 the first in the direct bloodline of modern transistors was made, again by Bell Labs – the metal-oxide-semiconductor field-effect Transistor (MOSFET).

Between then and now, most transistor technology has been based on the MOSFET, with the size shrinking from 40 micrometres when they were first invented, to the current average being about 14 nanometres.

The latest in transistor technology is called the RibbonFET. The technology was announced by Intel in 2021, and is a transistor whose gate surrounds the channel. The tech is due to come into use in 2024 when Intel change from nanometres to, the even smaller measuring unit, Angstrom.

There is also other tech that is being developed as the years march on, including research into the use of 2D materials like graphene.
