Henry, The gold deposit is fine but that doesn't mean that there isn't contaminates on the surface that would interfere with proper wirebonding. Also, any buildup of organics that codeposit as polymers will degrade the performance of the deposit. The only real test is to actually do the wirebonding and follow it with a pull test.
