We are having a discolorization problem with the gold fingers on our PCB's. I have been made aware that there is a gold touch-up paint (masking) that is available. Would anyone know where I can get my hands on some of it? Any help would be appreci

We have some circuit boards with some burnishing on the gold fingers from beveling. Does not go through the gold but is cosmetically noticeable. Is this a defect? Is it rejectable or cosmetic? Can someone tell me where the IPC deals with this? I ha

Hi Sal I've used the Stevens product for about 5 years and have nothing but good to say about them. pallets? can't say. The gloves simply extent the finger length by about 0.04" They come in 15" sticks so the length is up to you. Print/reflow contam

Gary: Two things: 1 Reworking golding fingers is an old topic, check the SMTnet archives to get started. 2 Gold fingers should not be discoloring, unless: * You are doing something bad to them ... OR * Your supplier has doinked the process, which

A paint might be pretty but it won't do anything but bad for your fingers. What dave is suggesting that you run a search for is actually a spot re-plating process that you can perform with little mess or fuss. But really, find out why it happened a
