Description

一种LED焊线线弧
技术领域
本实用新型属于LED封装领域中的焊线技术领域,特别涉及一种LED焊线线弧。
背景技术
焊线是LED生产中非常重要的一个环节,它是通过焊线机用金线将LED的支架管脚和LED芯片电极进行焊接,这样才能完成LED芯片的电气连接,使之发光。
由于支架负极离电极较远,且中间存在支架过道,在焊线作业5730机种时,焊线受热受冷不均,焊线由于自身物理属性产生热胀冷缩效应,微小的应变极易拉扯支架负极处焊点,导致支架负极处焊点断裂,导致死灯。
实用新型内容
本实用新型的目的是解决现有技术中焊线由于自身物理属性产生热胀冷缩效应,最终导致支架负极处焊点断裂问题,解决LED死灯,本实用新型提供一种LED焊线线弧。
为解决上述技术问题,本实用新型采用的技术方案为:
一种LED焊线线弧,它包括焊线及待焊线的支架,所述支架由支架正极和支架负极组成,其特征是:焊线一端焊接于支架正极,焊线另一端焊接于支架负极上,所述焊线为M形,M形焊线顶部两拐点处所呈锐角为57°,M形焊线中部拐点处所呈锐角为65°。
所述焊线材质为金及不可避免的杂质,焊线中金的纯度为99.97%。
由于本实用新型采用了上述技术方案,与现有技术相比,M形焊线顶部两拐点处所呈锐角为57°,M形焊线中部拐点处所呈锐角为65°,M形状焊线拉扯过程中会缓冲焊线内应力,降低支架负极焊点处受力,提高焊线品质,有效解决LED死灯问题。
附图说明
图1为现有技术中焊线结构示意图。
图2为本实用新型中焊线结构示意图。
图中,1为焊线,2为支架正极,3为支架负极。
具体实施方式
如图1~图2所示,一种LED焊线线弧,它包括焊线1及待焊线的支架,所述支架由支架正极2和支架负极3组成,其特征是:焊线1一端焊接于支架正极2,焊线另一端焊接于支架负极3上,所述焊线1为M形,M形焊线1顶部两拐点处所呈锐角为57°,M形焊线1中部拐点处所呈锐角为65°。
所述焊线1材质为金及不可避免的杂质,焊线1中金的纯度为99.97%。
以上所述,仅为本实用新型的具体实施方式,但本实用新型的保护范围并不局限于此,任何熟悉技术领域的技术人员在本实用新型揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本实用新型的保护范围之内。因此,本实用新型的保护范围应以所述权利要求的保护范围为准。
