Description

Technical Field

[0002] At present, there is no fully automated equipment for the disassembly process of PCB boards after lamination. Most of them are done manually to achieve the recycling of excess copper foil trimming and the separation of multiple panels. Some production process lines do not even trim the excess copper foil edges at all. The defects are as follows:

[0003] 1. Waste of resources and increased costs: Copper foil is a huge expense item in the PCB production process. In order to improve production efficiency, some PCB manufacturers do not cut and recycle the excess copper foil edges of PCB boards, which greatly wastes resources and increases corporate costs.

[0004] 2. Low operating efficiency: Nowadays, PCB boards are generally printed by manual labor to trim copper foil and separate boards. The cutting process line environment is generally harsh and the labor intensity is high. Repetitive manual operations are prone to fatigue, which will restrict production efficiency, thereby affecting the benefits of the factory and is not conducive to improving the company's market competitiveness.
