6-layer Automotive PCB

6-Layer Automotive PCB | Custom PCB for Intelligent Cabin Domain Controller

This 6-layer automotive PCB has finished dimension 207×167mm, board thickness 1.6mm. It adopts automotive-grade high Tg FR-4 substrate with ENIG surface finish, specially developed for passenger car intelligent cabin & body domain controller.

The PCB uses classic 6-layer stackup with separated power and ground planes, delivering excellent EMI shielding performance. It supports high-speed differential signals like CAN FD and automotive Ethernet to meet vehicle EMC requirements.

Designed with high-density BGA & QFN routing, fine trace and microvia technology. Contour is CNC routed with special cutout shape to fit vehicle housing assembly. The PCB can work under wide temperature range, anti-vibration and thermal shock, ensuring long-term stable performance for automotive application.
