过去我们生产印制板中的擦板工序,是操作者将双手泡在水里,用木炭把覆铜箔环氧酚醛玻璃布层压板表面上的氧化层擦掉,使板面光洁,然后进行贴膜、曝光、显影等项制板工艺。在制板工艺过程中,往往一个板子需要擦板2～3次。而且手工磨出的印制板易氧化,还需将半成品浸入重铬酸溶液内,这种溶液对人体有严重危害,废水溶液放出造成环境污染。为了提高产品质量,降低成本,减轻制板
In the past, we produced the board in the wiping process is that the operator will both hands soaked in water, with charcoal to the copper oxide epoxy phenolic glass cloth laminate surface oxide layer wipe off, so that the board smooth, and then Foil, exposure, development and other items system board technology. In the system board process, often a board need to rub 2 to 3 times. And manual grinding out of the board easy oxidation, but also the semi-finished products dipped in dichromate solution, this solution has a serious hazard to the human body, waste water solution caused by environmental pollution. In order to improve product quality, reduce costs and reduce system board
