What is Laminating Press

A laminating press is a process used to manufacture multilayer printed circuit boards (PCBs) that involves the fusion of the CCL (Copper Clad Laminate) core(s) of a PCB with copper layers and prepreg layers through the application of heat and pressure. This process is crucial for creating the desired structure and functionality of the PCB.

During PCB lamination pressing, a semi-cured sheet is subjected to high temperature and high pressure, causing it to melt and flow. This transformation results in the formation of a cured sheet, which bonds together one or more inner etched plates and copper foil, thereby creating a multilayer PCB. Prior to pressing, the process may also involve typesetting, drilling positioning holes, and shaping the laminated PCB.

Laminating presses are extensively utilized in the PCB industry for processing printed circuit boards, copper clad laminates, and various other surfaces. These presses can be customized to perform different functions and accommodate different materials. For example, they can be used for plastic card lamination, compression molding, or as a starter press for specific applications.
