Abstract

本实用新型公开了一种线路板电金用蓝胶,包括PVC薄膜层和覆盖于该PVC薄膜层一侧表面的胶层。该蓝胶在清除时不残胶,即使在焊接、研磨、烘干、电镀这样严酷的条件下也能与电路板精密贴合,使用后几乎能够无残胶剥离。

Description

线路板电金用蓝胶
技术领域
本实用新型涉及一种线路板电金用蓝胶。
背景技术
目前,在PCB或FPC制造行业的电金工艺中,均采用干膜来阻挡电镀和蚀刻。干膜是一种高分子化合物,通过紫外线的照射后产生一种聚合反应形成一种稳定的物质附着在线路板上,因此去除干膜工艺相对较复杂,容易造成线路板上残胶,在去干膜的同时容易刮伤电路,造成不良率扩大。
发明内容
为了克服上述缺陷,本实用新型提供了一种线路板电金用蓝胶,该蓝胶在清除时不残胶,即使在焊接、研磨、烘干、电镀这样严酷的条件下也能与电路板精密贴合,使用后几乎能够无残胶剥离。
本实用新型为了解决其技术问题所采用的技术方案是:一种线路板电金用蓝胶,包括PVC薄膜层和覆盖于该PVC薄膜层一侧表面的胶层。
作为本实用新型的进一步改进,所述蓝胶厚度为95-105um。
作为本实用新型的进一步改进,所述蓝胶的粘度为0.05Kg/25mm,抗张力为2.1Kg/10mm。
本实用新型的有益效果是:蓝胶替代干膜电金,是采用PVC薄膜涂特殊亚克力胶水组成,具有耐酸碱、抗腐蚀、清除时不残胶,PCB电镀、电金时必要的保护线路板用的特殊保护膜。在制作过程中方便、快捷、较干膜易剥除,清除时不残胶。
总之,电金蓝胶与干膜相比,有以下优点:
①易撕除:干膜要走去干膜线,而电金蓝胶直接撕除便可;
②板面残胶少:电金蓝胶撕除特别容易,不会出现板面残胶,对电路起到很好的保护作用,而去除干膜相对较复杂,在去干膜的同时容易刮伤电路。
③省时快捷:电金蓝胶较干膜可以减少很多不必要的麻烦,方便,省时,快捷。
