Hello, We are having issues to solder components. We investigate the issue and found that the pads were having extra gold on the sides. Is it normal? Can we remove this gold 'bleeding from our PCB?' Thanks

It appears the gold bleeding spans the gap between the plates, is this correct, or is it just the picture? If so, it should definitely be removed. Please clarify on what we are looking at.

Looks to me like under etching of the underlying copper and the gold is just plated to all of the exposed copper surface. Is this characteristic the same on all solderable pads? You will not be able to remove this gold.

We would agree with Pete B about both the under etching as a possible issue and you will not be able to remove this gold. Another possibility is the solder mask (plating resist) hasn't been taken right to the edge of the pad.

Hi Samuel, The issue your seeing is caused by lack of control of your board shops Immersion gold plating line. I would reject the order back to them. Their gold line baths need to be checked or they had a poor rinse after nickel plate before adding

Not exactly normal, I don't think. Though I have seen similar in the CM world. I can't think of a way to remove that overplating, either. If you can't reject the boards outright, then you might be looking at some touch up work, should bridging hap

Did I say leaching I meant bleeding. Doh!!

I agree with Doug. Stop the bleeding first, then find and stitch the wound up.

Is there any outcome?

Why does everyone tell me smocks will prevent ESD. They're not grounded, so how can they bleed or prevent ESD? They may not cause any ESD, but they sure don't come close to a heel strap or ESD shoes. OK, maybe from a "management" standpoint it mak
