Package Contamination on our IC
++++
I have problem in solder plating line. We find many package
contamination, such as white thin layer. We already clean all
chemical and rinse tank, but those contamination still occur. Do you
have suggestion about this problem ? Until now we still do not know
the material of this contamination. Our solder plating line were in
normal condition. May be you have the same experience with me.
