Hi, Does anybody know what is the minimum gold plating thickness on the PCB goldfinger required by the industrial specifications - IPC, Bellcore, etc. Where can I find the information? Appreciate for the help! Thanks, Tony

Flash gold is just thin electrolytic gold plating over electroless nickel or electrolytic nickel. Flash gold plating ... * Less than 3 microinch thick will be porous and take solder poorly * Greater than 10 microinch thick will cause brittle solder c

The answer, as stated above, is 3 microinch's however, it is equaly important, if not more important, to understand that the only function of the gold is to protect the surfaces beneath it. Only enough gold to cover the nickel beneath it should be u

From what I was told, gold flash normally refers to 10 microinches of gold.

What is the state of the art in electroplated gold flash a a surface finish; thickness and tolerance limits?

Matt: Yes, if the gold was really thick, it could appear like your pictures. In measuring gold plating thickness, we'd want to use xray fluorescence [XRF]. For alternatives, look here: http://www.pfonline.com/articles/pfd0027.html

Matt: What thickness of hard gold was applied to your customer's boards?

Not reflowing completely. Slower = hotter. Try a slower conveyor speed.
