In the PCB manufacturing, the through-hole acid copper plating requires quality phosphorus copper anode to create a quality layer to meet the standard of quick, efficient and stable plating. 
　　Our company applies advanced technology and complete set of equipment from broad to the production of quality PCB industrial phosphorus copper with the following advantages：
●　The phosphorus content is 0.05% with even distribution； the quick creation of anodic black film  in the tank, the even dissolution of the anode and the stable liberation of the copper ion guarantee the continuous, stable and quality plating.
●　The phosphorus copper has a high purity, over 99.9% copper content and few impurities, which greatly reduces the copper mud, facilitates the solution consolidation, and greatly extends the anodic bag replacing and the plating cylinder cleaning cycles.  
●　The phosphorus copper crystallize evenly and meticulous, with compact structure but without impurities or gas vent； the phosphorus content is evenly distributed so as to prevent the production of rough layer.
