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 electroless copper circuit board prices, the price is reasonable. Automatic additional copper plating solution. Electroless copper plating process, copper circuit board production process, the bath components consumed due to a chemical reaction, is constantly changing, and if you do not replenish consumed part, will affect the quality of the electroless copper plating layer, and, Since the composition of imbalance can cause rapid decomposition of the bath.

The easiest way is to use deburring from 200 to 400 water sandpaper polished copper surface after drilling. Mechanized deburring method is the use of deburring machine. Deburring machine brush roller is made of nylon or felt containing silicon carbide abrasive. General deburring machine deburring when, in moving along the direction of the board there are some glitches backward opening electroless copper inner wall of multilayer circuit boards, improved grinding plate machine, with two-way rotation with an oscillating nylon brush roll, in addition to Such ills.
