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

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?

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

I have lots of experience with thermosonic gold ball bonding. You can read the literature and you will probably find some papers that say you can do it. I have never been able to do it. We gold ball bond all day long with little problems at all bu

Haaaaa!!!! Soldering to plastic!!!! An apt analogy!!! I like to compare it to soldering to dirt. Some thing. In fact, you are soldering on nickel, when soldering on many things. It�s just that the gold, er Pd, flash enables the wetting mechanism

Hi, We have recently moved to flash gold as well, as we had solderability issues with emerson gold, and this was supposed to be a solution. However I did not know flash gold would be thicker, and could have other issues. Is flash gold a stable boar

Flash gold is just thin gold plating over electroless nickel or electrolytic nickel. Flash gold is electrolytic gold where the panel is connected to a plating rectifier and current causes the plating process to occur. Gold thickness is controlled b

I have no experience with soldering to a flash gold finish. We have specified ENIG for a prototype PCB order and the supplier is asking us if they can use flash gold. They are telling us that the two are interchangable which I don't believe. The

Flash gold is usually to thick and will cause embrittlement of your solder joints if concentration exceeds I beleive 6% in the joint
