There is a 8lb steel plate that is held down by 4 toggle bolts at the top of the machine. Its where you load the cutting media. If that plate does not have a pressure gauge built into it, contact CCR. They will send you one free of charge (at least t

We bought a conformal coating removal machine AKA a sand blaster at an auction. It is a CCR2000 especially made to be ESD safe. Does anyone have any experience with sandblasting conformal coating? We mostly use humiseal 1A33 and UV40. When we use the

We've never tried to remove Paraylene from a BGA, but we stayed [in seperate rooms] at the Red Roof Inn. Parylene/Paraxylyene is a great coating and can be selectively removed by several methods. IPC-7711 (Rework of Electronic Assemblies) has a sect
