Product Details Data Sheet

4-layer HDI PCB is widely used in:

Telecom module

wireless module

LED display module

HDI PCB (1+N+1): This is the simplest HDI PCB layout design structure, suitable for BGAs with fewer I/Os. It features fine lines, micro vias, and registration technology capable of 0.4mm ball pitch for excellent mounting stability and reliability, and may contain copper-filled vias. It is qualified material and finish for lead free process
