Hi DL:
这室内温度应该是多少是适宜的,存放期限是多久?这方面应该与MSD的要求有所不同,而且应该要求要宽松。

Hi Grace:
除了其他专家叙述的一些可能产生的原因,还有一种可能就是,对物料存储的要求
也就是环境(室内温度)

Hi Grace:
有没有可能存储不当或运输不当引起,比如会受潮引起这个问题。

有几种可能:
1. 料带上有静电,吸附了尺寸小的元件;---与料膜材质有关
2. 包装时料膜与纸质载带压得过紧,料带与料件之间有作用力;---与taping and reel制程有关
3. 料带被污染,黏附了小元件;---与料带或元件的洁净有关
以上是我遇到过的各种情况。

各位大虾:
请教一个问题,SMD料在机器打件过程中粘料是什么原因引起,如何避免。制程中如何杜绝此问题?谢谢!
