Black Pad

Black Pad | 9 October, 2002

We have been encountering black pad contamination on gold plated boards mainly affecting BGA components during assembly. This problem has been noticed with many of our customers that are using an array of fab vendors.

Does anyone have a solution for this or an idea of what causes black pad?

This is caused by PCB suppliers process.

Search the fine SMTNET archives for this as it has been discussed many times.
