技术领域
本发明涉及电子元器件领域,特别涉及一种电子元器件用封装膜。
背景技术
电子元器件是构成电子设备或者机电设备的重要组成部分,电子元器件的种类繁多,而且体积相对较小,在电子设备中常常较为零散地分布。但是,由于电子元器件在使用过程中,常常受环境(比如水、热等因素)和周围元器件的影响而产生变形、被氧化或其他理化损伤,从而影响现在设备的正常使用。
为了解决上述问题,一般采用橡胶膜等进行保护固定,比如中国专利申请CN103773257A,其公开了一种封装电子元件的胶膜,虽然该胶膜能在一定程度上解决问题,但是,该膜的机械强度仍然较差,而且且阻水防潮性能也较差,时间长了会造成电子元器件的氧化腐蚀。
