如果在PCBA表面有离子污染存在,极易发生电迁移现象,出现离子化金属向相反电极间移动,并在反向端还原成原来的金属而出现树枝状现象称为树枝状分布(树突、枝晶、锡须),枝晶的生长有可能造成电路局部短路。

PCBA清洗常用工艺,怎样清洗PCBA

现在,很多PCBA的生产制造中都用到了清洗工艺,对于不同级别要求的产品、采用的助焊剂以及经过的工序的差别,需采用的清洗剂、所需设备、工艺都不相同。大部分设备供应商都推出了清洗机设备及其清洗方案,并首先对制造工厂的焊接后的残留物的检测分析,然后给出针对性的系统清洗解决方案。有全自动化的在线式清洗机、半自动化的离线式清洗机、手工清洗机等,有适用于全水基(用离子水清洗)、半水基(用化学物质水溶液清洗,如皂化液)以及全化学溶剂的方式清洗。很多公司倾向于采用水基清洗剂,并向环境友好方向发展。全球知名清洗产品及技术支持供应商有ZESTRON、KYZEN等。
