Has anyone used the mechanical stencil foil tensioning system from certain company that eliminates using stencil frames and epoxy & mesh? Any comments on whether it's worth looking into? We go through product revisions like we go through clean sock

Hello all, Are BGA's easy to develope shorts? If a process is stable and all of a sudden you get BGA's shorting out on you, what might be problems? We've checked our solder paste amount, and we've rechecked our reflow profiles and nothing has chan

Hi, I am an Engineering student doing some research on the component/nozzle interface on SMT Pick and Place machines. Could anyone tell me the force at which the nozzle hits the component as it is picked from the feeder or the placement force on a
