Default contaminated soldering surfaces


"Jeff Liebermann"

Peavey Prowler amp from 1999. All the 1/4 inch sockets and one , only, of
the valve bases , bad solder joints, reacted to the re-soldering process
as
though the tags were made of stainless steel or had a grease/oil film over
them. What could have been the cause?


My guess(tm) is that the lugs were cadmium plated.



** Whaaaatttt ??


Cadmium can be
soldered with silver solder, but barely with regular 63/37.



** How are high volume manufacturers like Peavey supposed to use you
imaginary parts in automated soldering systems ?

Wot ********.
