Hello Corey, It is recommended that you not solder over a gold thickness of 30 uins, you will have gold embrittlement caused by the AuSn, intermetallic. If however, you reduced the gold thickness to < 10 uins, the solder joints will be stronger, with soldering to the nickel, beneath, occuring. Regards, Lenny Kurup EMX Enterprises Ltd.
