紫外激光切割机在FPC覆盖膜中的工艺应用-瑞丰恒紫外激光器分享篇
Release time:2021/09/15
柔性线路板(Flexible Printed Cirecuit, FPC)覆盖膜,主要成分为聚酰亚胺(Polyimide, PI) ,通常工业所使用的PI薄膜借助于粘合剂附着于纸质基底,呈卷状储藏,工业界也称之为PI覆盖膜,聚酰亚胺是分子主链上含有酰亚胺环状结构的耐高温聚合物,具有优异的综合性能,而耐热和耐辐射性能在目前工业化生产的高分子材料中极为突出。高温下具有突出的介电性能、机械性能、耐辐射性能和耐磨性能,广泛用于航空、兵器、电子、电器等精密机械方面。

自五十年代末发现了聚酰亚胺优良热稳定性和力学性能以来,人们对这类聚合物的研究- -直很活跃。然而,难以加工和较高的制造成本却严重限制了它的应用。
