Hey Jim, What can you tell us about the causes, results, and prevention of 'fretting corrosion' in connectors? Jim, I'm not adding this to insult you, but as a source of more information for those that are not familiar with the topic. Background o

Hi Guys, Currently im seeing corrosion on a gold pad as i shown in the picture. May i know is this corrosion or pad oxidation?? This defect were found after complete of all process including cleaning and im using water-soluble flux to run the produ

Ramon: I guarantee you there is corrosion on the solderable surfaces of your board. The issues are: * Flux selected is capable of removing the corrosion at hand. * Processes for applying the flux and soldering the board are effective for the sele

Hi Radek, Thanks for your reply. I use this flux with manual soldering process for the product. Is this flux suitable for manual soldering? or it is only for wave soldering? I have sent the board for analysis, and the report shown that the white res

Kevin: What was the thinking behind your using a flux that required cleaning �on a post wash assemble for a power switch�? How do you keep the remaining corrosive flux residues from causing trouble [ie, corrosion, CAF, etc]?

Thanks for response. I do wish to qualify that I got the alleged role of Nickel use for corrosion resistance from an article authored by Jason Gjesvold, IS IT REALLY BLACK PAD?, "Phosphorus rich Ni alloys are often used for corrosion resistance duri

Thanks guys. They are seen on some of the pads too. What will happen if I continue to solder them and I got a good solder joint formation? Will the pad continue to erode or corode in due time? or the solder that will recoat its surface will prevent

My frsh information from the fab is that: "Its Just A Bleedout" as to why? no response yet. as for "are they corrosion?" no response yet. as for "are they harmful and will they affect the reliability and integrity of the product?". no reply yet.

Hi All, Recently, I need to deal with a customer complaint that specify the PCBA white residue (flux residue from ecofree 303) may be the reason why the board intermittent. Anyone have such experience with this flux? Anyone can tell me is this flux
