光伏组件焊接良率提升

客户组件汇流条焊接虚焊率偏高,改用长先光伏专用助焊剂后,焊接良率由 97.3% 提升至 99.6%,单线年增产出显著。

The Challenge

客户产线采用自动串焊机进行汇流条焊接,原有通用型助焊剂在大面积焊接场景下润湿不足,导致虚焊与焊接强度不达标,良率长期徘徊在 97.3%。

Our Solution

长先提供 CX-FX-PV 光伏专用助焊剂,该配方针对汇流条大面积焊接优化了活性体系与挥发速率,确保焊料在有限加热时间内充分润湿。同时协助客户调整喷涂量与加热曲线。

The Result

焊接良率由 97.3% 提升至 99.6%,焊点抗拉强度提升约 15%。按客户单线年产能测算,年增有效产出约 2.3 MW,同时减少了返修工时与材料损耗。
