Multilayer PCB introduction:
Multilayer PCB's represent one of the most complicated products in the PCB industry. A breakdown of a multilayer PCB shows that it consists of three basic gid laminates, prepreg sheet for bonding the laminates and copper foils.
Purpose of Multilayer PCBs* To accommodate a larger of interconnections that steadily increasing use of high pin-count integrated circuits(IC).* To establish an electrical performance of the multilayer PCB, such as voltage and ground planes, EMC-shielding and circuit speed etc.
