In PCB manufacturing, the lamination process typically involves stacking copper foil, prepreg, and the pre-wired core (inner layer) in a specific order. The lamination process then passes through a press, initially hot-pressing the layers under high temperature and pressure to fuse them together. Cold-pressing then releases stress and ensures a flat product.

PCB is a crucial component in the electronics industry. Virtually every electronic device, from watches and calculators to computers and communications equipment, requires a PCB to interconnect electronic components such as integrated circuits.
