PCBs in car manufacturing

The industry is developing, and the old conventional rigid printed circuit boards have become unable to cope with the new realities.

For new cars, it is recommended now to use HDI printed circuit boards with a high density of interconnections; flexible and rigid-flexible PCBs.

Saifon Technologies can become your reliable supplier of PCBs for cars.

The company can not only fulfill your order according to samples, but also create a unique product for you.

Flexible-rigid and flexible PCBs have replaced rigid ones due to smaller dimensions, low weight, easy assembly and, more importantly, due to much higher rates of dynamic flexibility, thermal dissipation and system reliability.

Flexible and rigid-flexible PCBs for cars

Such PCBs create a reliable connection between rigid electronic components and cables.

In other words, they are much easier to mount, they cool better and do not take up so much space. On average, a flexible PCB weighs 75% less than rigid ones.

In automotive electronics, such PCBs are used for dashboards, circuits and controls, ABS systems.

It allows to solder components to the rigid part of PCB, when a flexible PCB transmits a signal where a rigid one would not cope due to its weak flexibility or thicker base. Such PCB has the advantages of both flexible classic PCBs and rigid ones.

In comparison with conventional rigid PCBs, such structures are smaller in size and weight, and the connections on them live longer due to reliability and resistance to the external environment. Such PCBs allow to completely abandon connectors.

Flexible-rigid PCBs

Flexible-rigid PCB is a hybrid that is designed with both rigid and flexible parts. Parts can be combined in different ways.

Either rigid and flexible layers go separately, or each layer has both rigid and flexible parts.

Flexible PCBs

Flexible PCBs are created on the basis of a thin material that is highly flexible due to the use of polyimide film or polyethylene terephthalate. Thanks to the high flexibility, PCBs can be bent without breaking or losing strength.

That's why they can be used for three-dimensional installation. They are able to bend the contours of electronic device blocks.

A PCB for manufacturing cars of any type – passenger cars, trucks – should have very high reliability and durability parameters of assembly units. How long the car will last depends on the PCB durability.

Why are hard PCBs no longer used?

Increased strength is needed since a car constantly encounters elevated temperatures, dirt, chemicals and high humidity on the road. Therefore, a manufacturer must consider all these things and still offer a competitive price.

A printed circuit board is one of the most important parts of any electronic product. It is difficult to overestimate the value of a part whose quality completely affects the final quality of the product. That is why it is important to choose a reliable PCB supplier. Such a supplier can be Saifon Technologies. The company considers all the conditions that PCB will face "in service" and develops models specifically for harsh conditions.
