All, We know that incomplete immersion silver could potentially lead this creeping corrosion. Is there any way to check bare PCB for incomplete immersion silver coverage, especially on the via hole area? Thanks, Sean.

Hi Chris, We've had another supplier say that it is the silver or combination of tin with silver that causes the corrosion. Would you agree?

We are using a Propyl Bromide vapor degreaser solvent. Has anyone heard of this solvent when used near an oven will decompose and cause major corrosion to metals such as in a Reflow oven or a wave solder pot?

This appears to be black-pad and is often the result of using specs that call for gold plating that is too thick. The black pad is corrosion that is created between the gold and electroless nickel during the gold plating process. This is counter in

Hi All, I have few questions about creeping corrosion that potentially happen on lead free immersion silver PCB as below: 1) What test that we can conducted to verify whether the failure we seen is due to creeping corrosion? 2) I heard that lead fr

Is this Corrosion? We found our boards with this issue 45 days after they were delivered to us from supplier. The board finish is HAL Leaded. But I noticed that the corrosion like issues are coming form the tiny via holes with SILVER EPOXY FILLING.

Gold should not be corroding in salt water. I have swum hundreds of miles in salt water with my wedding ring on my finger. My ring is a shiny and corrosion-free as the day it was cast over 120 years ago. It's possible that your gold thickness of 0.0

Pin holes in the gold can allow for corrosion of the underlying nickel and copper to form copper and nickel oxides on the gold surface (example - http://www.semlab.com/blog/?p=564. The corrosion can work itself all the way through the EN layer (exam

Is feasible to have an electronic manufacturing company near the beach? How affect the corrosion the electronic components?

is there any term called on that corrosion or green contamination?
