Exhibitors List of High Layer Count
High Layer Count (HLC)
Multilayer PCBs, servers, high-end computer boards, backboards, wafer test boards, etc., all have a high layer count. The difficulties in producing HLC boards lie in the interlayer alignment system. When there is a slight misalignment of the multiple layers, the vias may become conductive after drilling to result in a short circuit. Also, the lamination process is an essential factor affecting the reliability performance of the PCB after assembly.
