In the automotive circuit board, the traditional single-layer PCB, double-layer PCB and multi-layer PCB available, in recent years, the widespread use of HDI PCB automotive electronics products of choice. The essential difference between an ordinary HDI PCB and an automotive HDI PCB is that the former emphasizes practicality and versatility to serve consumer electronics while the latter is committed to reliability, security and high quality.
It is important to note that the rules and measures discussed in this paper are only some of the rules that are widely used, and do not include those special circumstances, since the vehicle covers a wide range of vehicle categories, such as cars, trucks or trucks, requiring different requirements for different performance expectations and functions The
Automotive HDI PCB Classification and Application
HDI PCB can be divided into three categories: single-layer HDI PCB, double-layer PCB and three layers to establish PCB. Here, the layer refers to the prepreg layer.
Automotive electronics are usually used in the following two categories. One is an automotive electronic control device until they work with mechanical systems on vehicles such as engines, chassis and vehicle control, in particular electronic fuel injection systems, anti-lock braking systems (ABS), anti-skid control (ASC), traction Control, electronic control suspension (ECS), electronic automatic transmission (EAT) and electric power steering (EPS). The other is a vehicle-mounted vehicle that can be used independently in the automotive environment and has nothing to do with automotive performance, including automotive information systems or automotive computers, GPS systems, car audio and video systems, automotive communication systems and the Internet. A large number of controls are implemented by HDI PCB supported devices.
