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 environmental quality circuit board is used for what areas, quality assurance, reasonable prices. Shanghai Meadville Ltd. 龚永林 for printed electronics engineer made a further explanation of environmental protection circuit board, he said characteristic green circuit board, printed circuit board manufacturing process is a conventional copper etching method, also known as a subtractive method. It is used as a substrate for copper clad laminates by screen printing or photo-imaging resist circuit pattern is formed where the need for environmental protection circuit board, obtained by the chemical etching circuit; if the double-sided or multilayer PCB but also for hole metallization and electroplating, to achieve inter-layer circuit interconnects.

Dipping process: dipping pieces immersed in the glue 2-5 s, slowly lift the dip pieces, tilt, until the excess glue natural run off, dipping pieces flat on absorbent paper (small pieces) or the holder (large pieces), generally within 30 min is dry, check the dip surface, no glue by brushing glue. Brush: Brush right choice by product scale, market to ordinary brush, the glue into the container, then brush the glue stick suitable for PCB uniform construction process, according to the required thickness for brushing times . Finished coating, surface curing can be assembled or packaged.
