Most of the flash gold coming out of China is electroplated soft gold and no more than 2 micro inches thick. If you are aware of Chinese suppliers that will exceed 2 micro inches of soft gold I would be interested. For the most part they are using baths that are designed for high current densities that minimize the time required to perform the process.
Best regards
Lee

Subject: Re: [TN] ENIG vs Flash Gold
my understanding of flash gold is electrolytic plated with 5-8 u-inches on
electrolytic or electroless Ni.
The ENIG is electroless Ni and immersion gold finishing. The gold quality
normally is inferior than the flash electrolytic gold... but, dissolution
rate in solder may be a bit slower compare to the ENIG of same thickness....
All the ENIG guys is going to shot me alive....

Flash gold is too general of a term. If you are to solder to the thinner
gold successfully it must be less than 20 uin.
