Hi, everyone
 I never used quartz wafer as the substrate before and I've heard it is
extremely frangible. Does anyone know the tricks to handle quartz wafer? Do
I need to buy special tweezers for it? How do you clean it? I would be
appreciate it if any of you could share your insights on it. The
specification of my quartz wafer is 3" with thickness=500 um (ttv<10um)
