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. Dan
