What is the difference between a car PCB board and a normal PCB board?


In terms of design and manufacturing, Car PCB boards have the following differences from ordinary PCB boards:

1. PCB material

Car PCB boards use composite materials, which are prefabricated materials roughly composed of two or more materials combined. This material can not only meet the requirements of Car PCB boards in high temperature and high humidity working environments, but also effectively reduce the noise and interference of vehicle circuits.

2. PCB thickness

Car PCB board requirements are more stringent. Ordinary PCB boards are generally 0.2-3.0mm, while Car PCB boards are usually 0.6-3.2mm. This is because the working environment of Car electronic components is harsh, so in terms of the thickness of the PCB board, the Car PCB board must be more durable and stable.

3. PCB special process

Car PCB boards also need to undergo a series of special processes, including waterproof, dustproof, shockproof, impact resistance, etc. These processes can not only protect the components and circuits of Car PCB boards, but also effectively reduce the failure rate of automotive circuits.

4. PCB circuit design

Car PCB boards not only require the safety and reliability of the circuit, but also need to consider the durability and stability of the automotive circuit. Therefore, in the circuit design of automotive PCB boards, more working environment factors, such as temperature, humidity, dust, etc., need to be considered.
