以ENIG表面处理与SAC305形成焊锡的剪切力测试来看,不论是一次回焊、二次回焊、回焊后放置于150°C环境下200(H)小时来看,其破裂强度(焊接强度)似乎没有特别明显的差异。 相对来说,ENIG一旦经过设计信赖度品质验证,日后在市场上的不良率应该比较低,但前提是不计「黑垫」这类PCB生产时的瑕疵。
Solderability: when utilizing OSP as a surface finish for your PCB, you must avoid solderability issues. When there is a problem in solderability, it restricts the PCB performance. Duration of application: when implementing surface finishes, some surface finishes take longer than others. However, ap...
Every PCB will have a surface finish. They provide protection for the exposed copper parts and offer better solderability than what bare boards can.
