FPCB对表面处理工艺要求也越来越高，主要表现为在同一产品表面上同时存在多种表面处理方式。由于每种表面处理工艺使用到化学药水特性不同，必须逐一对产品表面进行加工，且在进行混合多次加工前需对产品不同区域表面进行保护处理，以防出现漏镀、渗镀及表面残胶等品质异常。%FPCB products have higher requirement on product surface treatment technology, which mainly shows out such as in the same products at the same time there are a variety of surface treatment on the surface. Because each surface treatment process uses different chemical liquid with different characteristic, the product must be made one by one. The product surface processing with mixed pre-processing many times in different areas of product surface need protection treatment to prevent leakage on the plating, plating surface quality problems such as glue.
