Werner This could not be flash gold since in this process the gold thickness is approximately 2 micro inches, which of course is where the name originated. The advantage over ENIG is that the porosity is greatly reduced. I am sure you will agree two micro inches of gold is not going to cause embrittlement. I imagine what you have is typical plated gold with uses a completely different and much more expensive chemistry. Best regards Lee J.
