Description
Electroless copper plating is also called sinking or porosity (PTH), which is an autocatalytic redox reaction. First, it is treated with an activator to make the surface of the insulating substrate adsorb a layer of active particles. Metal palladium particles are usually used. (The colloidal copper process is running), copper ions are first reduced on these active metal palladium particles, and these reduced metal copper nuclei themselves become the catalytic layer of copper ions, so that the reduction reaction of copper continues on these new copper The inspection is done on the surface.
The process flow is as follows:
Drilling → grinding plate deburring → upper plate → whole hole cleaning treatment → double water washing → micro-etching chemical roughening → double water washing → pre-dip treatment colloidal palladium activation treatment → double water washing → degumming treatment (accelerated) → double water washing → sinking Copper → double water washing → lower board → upper board → pickling → one time copper → water washing → lower board → drying.
