Good Morning Techies,
We have a customer with a question: Is there a standard that addresses
copper inclusions under the solder mask? It appears the PCB's were not
cleaned very well before they were masked. There are little bits/threads
of copper under the mask, but they are not vioilating any clearance
requirements. I don't remember ever seeing anything that specifically
addresses this. They are not necessarily calling it a defect, but are
wondering if there is something that addresses this.
Thanks for your time,
Connie M. Korth
