先AI后再SMT,因为红胶是點膠机點的.基本AI不會走锡膏制程.不知其它前輩家怎么做的.能否分享?

 对于AI与SMT的先后,以我的经验来说,是先SMT后再AI,因为如果AI后再SMT,怎么印锡膏或红胶?

 对于SMT后再AI会掉件,主要发生在红胶网,则需考虑红胶量,根据不同元件大小

决定开孔。

 

Thanks & Best Regards,

谢谢!

在上周外出审核钢网供应商时了解到一个情况,向大家了解一下,

就我们以前的经验,如果产品需要进行AI和SMT(红胶工艺),通

常是先AI后,再用铜网或胶网刷胶。但也有公司会先SMT后再AI。

通常我们认为如果采用第二种方式可能会导致掉件和元件损伤。

请问是这样的吗。有没有谁有这方面的经验。

谢谢!

您好!

     很少有钢网checklist。Intel公司审核过允升吉钢网厂家。但是没有见过intel的checklist。个人经验:

(1)激光切割机的定位精度。

(2)钢网开口尺寸的一致性。

(3)钢网开口的位置精度。

(4)孔壁粗糙度。
