HI..anyone who can give me a link to enlighten me on this plating for pb-free..Most people say this is the same? ARe they really? or different in process?? ..Any info on best storage for this plating? I have read all those stuff like avoiding sulfuri

Hello guys! I have a question for you guys, we have been working with a cleaning agent call Safewash (SWAS) from electrolube, we use this safewash to clean the flux residue from the boards after wave soldering, since or customer doesn't like to have

Ken, The photo looks like results I have seen because the gold flash was too thick on the board. This causes a condition known as gold imbrittlement. You may want to get an analysis of the plating thickness. I'm not real experienced with immersion si

The company that does this is McDermid. There are multiple different ways of doing it. Screen print silver paste onto the mylar, "activate" the film to be conductive, then plate in copper. These processes are found in the patent literature which is e

Hi, Did anyone experience a problem with electrically conductive silver filled epoxy is resistive due to galvanic reaction? I'm having this problem when attaching components to Ni plated housing while conducting an experiment to cost reduction for Au

To get real conductivity in your traces you will need to remelt your copper or silver tracks. This means 850oC. The other method is plating at low temps, or etching. Epoxies like all carbon based compounds vaporize at 400oC. Next problem epoxy fibre

Here is some food for thought. Try to answer these questions yourself and I am sure you will see huge improvement. Reasons: - Bad PCB design - Plating-uneven HASL cause more than OSP Au/Ni or Silver - Poor paste and print quality - uneven paste ca

Ugh, there are more reasons that immersion silver [IAg] to go yellowish than pigs at the county fair. That aside, sulphur is one of the reasons, as you say. The sulphur can be from a variety of sources, such as: * Pollution in the air * Ill advised p
