Solder on gold finger

Solder on gold finger | 26 July, 1998

We are trying to reduce the number of units fail at system test due to flux on gold finger. We know so far that the flux is deposited onto the goldfinger during touch-up or rework and to reduce the contamination we are planning to implement 'taping' the gold finger during touch up. Need some advice on what kind of tape we should use or is there any other simpler solution that we can implement. Thank you and really appreciate the help. Masdi Muhammad, Process Engineer.

Re: Solder on gold finger | 26 July, 1998

Masdi, Try board shunts. They are hi-temp rubber strips with grooves cut. They can be popped on and off with ease and are much faster than taping and considerably cheaper. They also work great for masking goldfingers prior to wave soldering.

Are you using no clean flux or waster soluble flux? if WS flux , after rework you have to wash the board thru the cleaner.If no clean flux were using ,use the flux pen and you don't have to tape the gold finger with the kapton tape..don't use the litle bottle container. Hope this help Rin

Tape and shunts are good ideas for WS *BUT*... | 28 July, 1998

Right now we are taping the goldfingers which is effective but also expensive. Also, some tape was leaving yellow marks on the goldfingers. We're trying the so-called goldfinger glove from Steven's Products. It's a very small company (probably one guy) and they'll give you a hard time if you want custom sizes or to specify your own tolerances, but the fiberglass gloves do seem to work. They're about $3.50 each in low quantities.
