Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 layer multilayer professional providers, to provide customers with high-precision, high Shenzhen circuit board quality, quality assurance, reasonable prices. In order to improve the stability characteristics of the copper layer and the bath can be a certain amount of additives in the electroless copper plating solution. After the addition of additives, in most cases it is to make the deposition rate of electroless copper plating solution becomes low. The content of the additive is not too high electroless copper multilayer circuit board, adding an excess of additives tend to make copper reaction. Plating bath temperature was raised to increase the rate of the temperature, but with the bath temperature rises, increase side reactions, the bath unstable. Therefore, different electroless copper plating solution, temperature has a limit working temperature limit is exceeded, the stability of the bath significantly deteriorated, resulting in the rapid decomposition of the bath.

Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 layer multilayer professional providers, to provide customers with high-precision, high Shenzhen circuit board quality, quality assurance electroless copper circuit board prices, the price is reasonable. Capacity up Objective: to soften the bulk epoxy resin, can reduce bonding between the polymer, so that the early formation of KMnO4 more bite eclipse rough surface can reduce the dissolution weak bonding to bond with significant differences. If you soak too long, strong bonding is also gradually reduced, which ultimately caused the piece to a low bonding surface can be increased, if it reaches such a state electroless copper circuit board manufacturers, will not form a junction of different strength .. If immersion is too short, it can not form a low bonding and bonding difference, so the bite KMnO4 eclipse is difficult to form a honeycomb surface, which ultimately caused the affect PTH effect.
