aluminum wire bond?  usually no problem on quartz, unless you  
directly bond  on top of the structure (MEMS for example).  As for  
gold plating lift off, either you have over travel of bond head  
(wedge), smash (force) too much, or your gold seed layer adhesive not  
strong enough (chemical seeding, instead of good  sputtering)... IMHO  
(old info... more than 10 year old.. for your reference only).
