Hi,

Can someone recommend IPC or other specs that deal with thickness
specifications for gold flash and/or plating on PCBs? Any other sources of
information or recommendations would be appreciated as well.  I have a
customer who needs plated gold for wire bonding but in the interest of
saving money, they've elected to have the entire PCB plated with 80-100
microinches of gold. This is causing us alot of problems with solder joint
quality in terms of brittleness of the joints. I'm trying to offer them some
alternatives, but am not that familiar with what's considered "standard".
Any insight would be greatly appreciated.

Thanks.
