Guenter, If you have access to it, Mil-Std 883, Test Method 2010 - Internal Visual Monolithic, and test Method 2017 - Internal Visual Hybrid both cover the visual appearance of ball-wedge bonds as well as wedge-wedge bonds, beam lead, etc. I have generically felt that the Mil Std's specification for Max deformation has been too great. If I ever squashed the bonds out that much, I would consider them to be over-bonded and weak. I believe very strongly in wire pull data vs 'looks'.
