1、 Material Selection

There are certain differences in material selection between automotive PCB boards and ordinary PCB boards. Ordinary PCB boards usually use FR-4 glass fiber materials, while automobile PCB boards need to choose higher level materials, such as FR-4 HTG materials or polyimide materials with better high temperature resistance. This is because automotive PCB boards need to have better stability and reliability in high-temperature environments.

2、 Process Requirements

There are also differences in process requirements between automotive PCB boards and regular PCB boards. Due to the need to withstand stricter working environments and vibration impacts, the process requirements for automotive PCB boards need a more higher level. For example, automotive PCB boards require stricter welding and protective treatment to ensure circuit stability and reliability. In addition, automotive PCB boards also need to meet higher fire resistance and corrosion resistance requirements.

3、 Environmental Adaptability

Automotive PCB boards and ordinary PCB boards also differ in environmental adaptability. Ordinary PCB boards are mainly used in general electronic devices, with relatively low environmental requirements. And automotive PCB boards need to adapt to more complex automotive working environments, such as high temperature, low temperature, humidity, vibration, etc. Therefore, automotive PCB boards need to have better resistance to high temperature, humidity, and vibration.

4、 Reliability

There are also many differences in reliability between automotive PCB boards and regular PCB boards. Due to the more important role played by automotive PCB boards in automotive electronic systems, their reliability requirements are higher. Automotive PCB boards need to withstand the test of long-term work and harsh working environment, so they need to have better anti-aging, anti-corrosion and anti-interference capabilities. In addition, automotive PCB boards also need to undergo strict reliability testing to ensure their stability and reliability under various extreme conditions.

There are significant differences between automotive PCB boards and ordinary PCB boards in material selection, process requirements, environmental adaptability, and reliability. The automotive PCB board has important application value and development prospects in the field of automotive electronics. With the continuous development of automotive electronic technology, the demand for automotive PCB boards will gradually increase, and the requirements for their quality and reliability will also become more and more stricter. Therefore, the research and production of high-quality automotive PCB boards is crucial for the development of the automotive electronics industry.
