Description

一种单层线路板组合到排线上制成的双层线路板及制作方法 技术领域
本发明涉及LED灯带及广告招牌领域,具体涉及一种单层线路板组合到排线上制成的双层线路板及制作方法。
背景技术
现有技术制作在一个平面上多次转弯粘贴的灯带,主要用于广告招牌发光字行业,以及灯箱行业,现有技术用在这个行业的柔性线路板灯带,用的是以下几个方案:
1、单层线路板两边多处缩窄,缩窄的目的是便于在一个平面上转弯容易,业界称为S型灯带,这种线路板最大的问题是由于多处缩窄,导致从头至尾的长灯带的主线也在一层线路上,而且因为缩窄导致主线变小,再加上灯带整体也不能做太宽,太宽不易转弯,而且做小字时安装空间受限,所以,就导致在比较窄的线路上,部分位置还要收窄,导致主线布得很小,导致灯带首尾间压降大,尾端亮度降低。业界用这种灯带做广告字时,都要外加导线去补电,减少压降,而且安装时工作量,综合成本很高。
2、双层线路板两边多处缩窄,缩窄的目的是便于在一个平面上转弯容易,业界称为S型灯带,这种线路板虽然通过做两层后,主导线加大了,但是又带来另外的问题,双面板灯带转弯弯折时,上下两层铜互相顶,容易将线路顶断,所以,铜厚更不能做厚,做厚了更硬,转弯时更容易顶断,同时,还是存在由于多处缩窄,导致从头至尾的长灯带的主线也因为缩窄导致主线变小,再加上灯带整体也不能做太宽,太宽不易转弯,而且做小字时安装空间受限,所以,就导致在比较窄的线路上,部分位置还要收窄,导致主线布得还是不够,导致灯 带首尾间压降大,尾端亮度降低,业界用这种灯带做广告字时,都还是要外加导线去补电,减少压降,而且安装时工作量,综合成本很高。
3、业界也还有用完全直条的灯带做广告字,这种虽然压降小一些,但是转弯很困难,基本处于淘汰产品。
为了克服以上的缺陷和不足,如何做长压降小,又能便于转弯,又能转弯时不易断裂,又能在安装使用时,不外加线补充电,又能将综合成本降低,本发明将一种单层线路板组合到排线上制成的双层线路板,用这种线路板做灯带,将作一单层含多条灯带线路板的连体柔性线路板,在线路板上用模具冲切形成多个镂空的孔,在背面多个位置施加胶粘剂,再制作一排线,用带胶的膜粘贴平行导线制成排线,排线上多处有导线金属露出,再将排线切成多个缝隙,将线路板和排线对位贴在一起,形成含多条灯带线路板的连体双层线路板,此双层线路板是多处分层的线路板,在双层线路板里的每条单层线路板的边缘处,正面的单层线路板多处收窄,而且在收窄处(不限于收窄处)和背面排线形成分层的结构,背面排线在收窄处又自身形成有缝隙,用这种线路板制成的单条LED灯带,背面贴到一个平面上使用时,在收窄分层处便于转弯安装。
或者,将作一单层含多条灯带线路板的连体柔性线路板,在背面多个位置施加胶粘剂,再制作一排线,用带胶的膜粘贴平行导线制成排线,排线上多处有导线金属露出,将线路板和排线对位贴在一起,形成含多条灯带线路板的连体双层线路板,此双层线路板是多处分层的线路板,用模具冲切或用激光切割成多个镂空,在分层位置(但不限于分层位置)形成有镂空,而且是在连体线路板里的每条单条线路板的中间形成的多个镂空洞,用这种线路板制成的单条LED灯带,背面贴到一个平面上使用时,在收窄分层处便于转弯安装。
本发明解决了背面排线因为在转弯处已经分层,又是正负极切开分开了,转弯时互相不挤压不顶,可以把线加大,满足负载要求,而且相当于是把使用安装时用的线拿过来整合到了一起,并没有增加铜 线的成本,反而集层到一起了,安装效率高了,综合成本大大降低,而且广告字里没有了乱七八糟的接线。
