Domestic manufacturing increases consumer cost

Domestic manufacturing increases consumer cost

Since the introduction of the Chips Act increased costs were a cause for concern. Many manufacturers and suppliers have expressed a worry that the various cost increases involved in reshoring production would affect business. The major impact of this would be a raised cost of consumer electronic devices at the end of the road.

The upside

With the Act in place, and export restrictions on China being introduced, the chip industry faces an interesting predicament. On one hand the Act will increase the number of jobs. It could also give the US a more stable position in the global market. Not only that, but it will encourage foreign investment in the US economy and bring consumers to domestic producers.

All in all it is expected to improve the US chip industry hugely, and the profits and products of it will mean America is a real competitor in the market.

The downside

Unfortunately, though, there are a few downsides as well. The cost of most things, including building new fabs and training new staff, is more expensive in the USA. There is currently much less semiconductor infrastructure in place here.

Compared to countries like Taiwan and China, which are already set up for mass production, the US will have to invest a great deal of time and money. Additionally, the labor and equipment is cheaper in Asian countries. Some experts in the industry have predicted the cost of making a chip could increase by 40%

According to one research firm, the cost of a fab in the US can be 80% more than in Taiwan. This isn’t exactly attractive for investors.

The impact on consumers

There has been a massive range of estimates on how much the end-user will be affected by reshoring. One of the most often-discussed products is the smartphone. Providers like Apple and Samsung have had to reorganise thanks to the Act, and change their future plans.

In addition to the chips needed for the phone itself, the cameras also require separate chips and components. The cost of a new iPhone, for example, could increase by $100. Other experts have estimated eye-watering estimates of a $30,000 increase, but this is less likely.

Many companies are expected to try and mitigate the cost passed onto customers. It’s worth noting it won’t be possible, or economical, to do this entirely. There are incentives included in the Chips Act to offset these costs too, but those will only go so far.

The inner workings of a flexible screen

The inner workings of a flexible screen

Flexible screens that the consumer can fold or roll were once a complex novelty. Now, they are becoming increasingly more commonplace.

More and more phones and electronic devices are offering flexible screens. Only recently were the newest Samsung Galaxy phones released with folding screens. Oppo, LG and other providers are also beginning to offer flexible screens for their devices.

The first phones with curved displays were produced in 2014 when plastic joined glass as a screen substrate option. The flexible plastic could be bent without breaking, and was much more durable than a thin fragile sheet of glass.

Any kind of screen needs to be durable, but the necessity is increased when flexibility and folding is considered. The other layers of the device have to be just as flexible and durable, which is a factor that has led to a much longer development time.

I don’t believe my eyes!

OLED is currently the display of choice on flexible screens, often being chosen over the LCD alternative. Unlike the backlit LCD screen, the pixels themselves are what emit light in OLED. Thanks to this OLED screens can be much thinner and lighter.

Aside from the cover layer, the glass or plastic layer we interact with, and the OLED, there are two other layers in a flexible touchscreen device:

The substrate layer, which is the bottom layer of the screen, supports the layers that follow. This is usually made of plastic or metal. The most common substrate used for flexible devices is polymide, which has a high mechanical strength and thermal stability. This is also usually used for the cover layer as well.

Powered pixels

The thin film transistor (TFT) layer is between the substrate and the OLED layer. It controls the power delivery to each pixel individually, allowing for high contrast rates and lower power consumption.

Within the TFT layer itself there are also several components that go into its construction. The first layer is glass, metals and polymers and is only microns thick.

Next, there is a gate electrode made of aluminium, gold or chromium. The gate electrode provides a signal to the TFT which begins the contact between the source and drain.

The third layer, an insulator, is used to stop electrical shorting in between the two layers. After that there is another electrode layer and is deposited over the semiconducting surfaces.

Is it possible to make compostable PCBs?

Is it possible to make compostable PCBs?

Decades ago we wouldn’t have thought it possible to create printed circuit boards (PCBs). Now, in 2023, we’re discussing the possibility of biodegradable ones.

A research group from the Johannes Kepler University in Austria developed the biodegradable base for the PCBs. The mix consists of beech wood shavings, organise full-grain spelt flour, fine plaster (CaSO4) dust and beech wood-based inoculum.

After storing the mixture in a flat plastic box in a cupboard for a few weeks a tissue grew. The fungal fibres, called mycelium, formed a kind of soft white skin, similar to paper.

A layer of copper or gold is then vapour-deposited onto the mycelium ‘skin’. Then, a laser will cut away the metal where it’s not needed.

A ‘grow-your-own’ circuit

Storing something in a cupboard for a few weeks has significantly lower production costs than regular PCBs. It also bypasses the need for chemicals and minerals that are hazardous to the environment.

With the use of these, too, there is no need to create specialist manufacturing equipment, unlike with biopolymers. They are made from renewable raw materials like starch or milk protein, but have to use an industrial composting plant that operates at a high temperature.

These ‘skins’ can then be mounted with electronic components like a regular PCB.

The mycelium has a very strong structural integrity, while it remains thin and flexible. It has so far been able to withstand about 2,000 bending cycles, it only shows moderate resistance when folded, can insulate electrical currents and can sustain temperatures that reach 250⁰C.

Early days

So far the concept can only be used in simple electronic devices. A multi-layer circuit or more complex electronics are slightly further in the future. Even at this early development stage, though, a prototype has already been attached to a moisture sensor, a Bluetooth chip that sends the sensor signal to a laptop or smartphone, and a special battery.

In the future it is hoped that production of a smoother mycelial skin through a refined formula could increase the possibilities. It could lead to multi-layer PCBs with smaller components.

Once the circuit has been used, it can be unsoldered and put in the compost. The metal used I the conductor paths will be a biproduct left in the soil, but will be nano-particles in unharmful quantities.
