We reball hundreds of BGAs a week with the RB-2000 kit from Mini Micro Stencil, Inc. The reball stencils are made of stainless steel and can be used over and over again. We have reballed .5mm pitch parts with .012" balls up to 2400 ball BGAs.

What is your opinion of this frameless system? How long have you had your system? How many cycles on your stencils? Any issues you are not happy with? How is storage working for you? Any issues with cleaning?
