Acme Circuit is one of the successful manufacturer and exporter of multilayer PCB. A multilayer PCB is made by combining several thin printed circuit boards. These boards are etched in separate processes and then glued together into a multilayer PCB. It contains trace layers inside the board providing connection between layers. A component housed on the outer layer of a PCB can have a connection with any layer via specially fabricated micro-holes that has been made using finest drills. Double layer PCBs (otherwise called double-sided plated thru) circuits will be the entrance to raised innovation applications. https://www.acmecircuit.com/service/double-layer-and-multi-layer-pcb/
