一种间断分层的柔性叠层线路板灯带及制作方法 技术领域
本发明涉及LED灯带领域,具体涉及一种间断分层的柔性叠层线路板灯带及制作方法。
背景技术
LED线路板灯带一直来,使用时很多位置根据需要都要弯曲使用,通常灯带在弯曲使用时,都非常容易造成线路板弯曲断裂,或者线路板断线,或者长灯带在安装时因自身重量重,因拉伸而断裂,或者是灯带线路板背面有厚的铜线或者铜排线,弯曲时,厚铜把线路板顶断,或者是灯带包的防水树脂弯曲时把线路板顶断,加之一些长灯带都是用焊锡连接的方式制作长灯带,但是,当需要制作超长灯带时,因负载大,载流量大,就必须要用厚铜做电路导体,然而,需要焊接连接的铜越厚用锡焊越不牢固,抗不了挠折,如何解决这个弯曲及拉伸易断的问题,提高抗挠折能,一直以来是业界的一个难题。
为了克服以上的缺陷和解决以上的技术难题,本发明将灯带线路板制作成间断分层的柔性叠层线路板,将正面焊元件的单层或者双层柔性线路板,在背面局部间断印刷胶粘剂,再与背面的金属单层线路板粘贴在一起,形成间断粘合,间断分层的结构,大大提高了灯带的耐弯折性,解决了灯带在安装使用时诸多因素导致的断板问题,本发明还采取铜自身焊点融化融合在一起的方式,将多条短灯带首尾正负极铜焊接,制成的长灯带非常牢固,绕折时连接位不断裂,解决了传统锡焊抗挠折,抗拉强度不够的问题。
