Sure it will. Compare with conformal coating on PWBs. Correctly applied the coating minimizes the migration risk, even if it's not 100% eliminated. /Inge -----Ursprungligt meddelande----- Från: TechNet [mailto:[log in to unmask]] För Anat Douek Skickat: den 4 december 2007 08:11 Till: [log in to unmask] Ämne: Re: [TN] SV: [TN] FW: shorted feedthus due to silver migration Thank you for the answer. I know that migration caused by the silver plated feedthru. The question is if non conductive epoxy which will cover feedthru body can prevent the short.

Your silver migration is probably caused by the silver plated feedthroughs. We NEVER us Silver. Our glass beads have gold flash over nickel over the base metal. /Inge -----Ursprungligt meddelande----- Från: TechNet [mailto:[log in to unmask]] För Anat Douek Skickat: den 3 december 2007 15:09 Till: [log in to unmask] Ämne: [TN] FW: shorted feedthus due to silver migration Hi, I am facing a problem of silver migration with soldered feedthru. The silver plated feedthrus are soldered to an aluminum housing and +60V is applied to the feedthru's pin. After period the voltage fall down and silver residues observed on the glass insulator . These residues caused the pin to short to the body. Is epoxy adhesive which will cover the feedthru body , after the soldering, can be a solution ?
