Background

PCB boards, also known as printed circuit boards, are providers of electrical connections for electronic components. Its development has been over 100 years old, its design is mainly territory design, and the main advantages of adopting circuit board are that the errors of wiring and assembling can be greatly reduced, and the automation level and production labour rate can be raised. The circuit board can be divided into a single-sided board, a double-sided board, a four-layer board, a six-layer board and other multi-layer circuit boards according to the number of the layers of the circuit board. Since the printed circuit board is not a general end product, it is somewhat confusing in the definition of the name.

Electroless copper plating is a process in circuit board manufacturing, and is also commonly referred to as copper deposition or voiding as an autocatalytic redox reaction. The first treatment with activator to make the surface of insulating base material adsorb an active layer of particles is usually metal palladium particles (palladium is a very expensive metal, the price is high and is always rising, and there is practical colloidal copper technology in operation at present abroad to reduce the cost), copper ions are firstly reduced on the active metal palladium particles, and the reduced metal copper crystal nucleus itself becomes the catalytic layer of copper ions, so that the reduction reaction of copper is continuously carried out on the surface of the new copper crystal nucleus. The existing copper plating device has the defects of easy bubble generation, influence on the quality of a PCB, complex structure and incomplete copper plating, so that the development of the PCB copper plating device which is not easy to generate bubbles, does not influence the quality of the PCB, has a simple structure and can completely plate copper is urgently needed.
