I am not quite clear what you are asking, but I'll give it a shot. Once the P&P program is put into the machine, the operator will load a bare board and step through the program using the machine camera to verify that part outlines match up to the bo

Because we build Class 3 assemblies, our company has formal inspection steps on our routes. CCA's go through surface mount and then an operator inspects the solder joints for defects and corrects them (touch-up). Following this they go to formal insp

Good day, 2D inspection requires correct adjustment. In the other case it will cause continuous problems and false alarms. Adjust the lightning first and choose the correct process limits second. Look at histogram when you are adjusting the camera

Now that is a BIG step. Stencil type: * A metal squeegee is fine with stepped stencils. * A rubber squeegee is fine with stepped stencils. Comments on step stencil "keepouts" are: * Use an ample space around the stepped down component pads that is
