Multiple Layer PCB Introduction:
Multiple Layer PCBs, also known as multilayer printed circuit boards, are advanced electronic circuit boards that consist of more than two conductive layers. These intricate designs offer enhanced functionality, improved signal integrity, and increased component density compared to traditional single or double-layer PCBs.
