	Hi folks!!!  Looking for some standards for HASL of PCB's.
        Having some difficulty educating customers about crowning, 
        puddling, heavy solder coating, etc.  Obviously, with some
        20 mil pitch lead devices, placement is a challenge--at best.
        With a convection oven, it becomes very interesting.  Does 
        anyone out there have similar problems?        

       What are people specifing for pad height of HASL solder?
