Printed circuit boards has many applications in countless sectors ranging from healthcare to electronics, but their impart is perhaps the most evident in the automotive industry. So what are these special types of PCBs made up of? Let's have a look.

Led PCBs

The LED boards made of aluminum substrate since they require heat dissipation. They can be found in car indicators, headlights, and brake lights.

Flexible PCBs

Automotive applications, in particular, carry a number of advantages, not only in the usual arena of reliability but even more so for the weight savings that a flex PCB offers compared with a standard PCB and wiring harness. Flex PCBs greatly reduce the labor involved in manufacturing a traditional automotive wiring harness. And the inherent resistance of flex PCBs to vibration makes them ideal for the harsh environment inside a motor vehicle.

Heavy copper PCBs

The Automotive PCB employ thicker copper (Cu) in the outer and inner layers of the boards. These heavy copper boards are preferred over the regular ones since they can withstand high temperature, high frequency, and high current variations. The regular boards display a copper thickness of around 25µm to 50µm. Whereas, the heavy copper PCBs will be 150µm to 200µm thick. These boards are implemented in safety and signaling systems.
