Automotive Electronic Circuits

Importance in Automotive Electronics

12-layer PCBs provide the foundation for modern automotive electronic circuits. They play an important role in fast-tracking reliable interconnections. This PCB has a variety of uses, including navigation systems, transmission control units, electronic ignition assembly systems, and other components of the vehicle.

Design and Material

Stress and Temperature Resistance

The 12-layer PCB is designed to withstand stressful conditions and high temperatures. The main material used here is polyimide. This polyimide material is organic in nature and has good heat resistance.

Gold Finishing

Gold is used by some of the top PCB manufacturers when finishing 12-layer PCBs. This is because it plays a huge role in resisting harsh environments. นอกจากนี้, some applications where heat sinks are added to ensure that the PCB operates at high temperatures dissolve easily.

Thermal Stress and Cost

At 288 degrees Celsius and 20 seconds, the 12-layer PCB experiences thermal stress while its impedance is controlled around +/-10%. The cost of purchasing a 12-layer PCB is affordable compared to other multilayer boards such as 8-layer and 10-layer.
