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 elements: thin rigid laminates,
prepreg sheet for bonding the laminates and copper
foils.
Purpose
of Multilayer PCBs
* To accommodate a larger number 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.
