| Tony | | Although I agree in principle with Dean that 45 Degrees would be ideal, most of the squeegees I have worked with have been 60 Degrees to the stencil surface. This seems to work best with metal squeegees when printing HASL boards, because

| I am in need of feeder that that will feed a 76mm wide tape @ a 60mm pitch to be used on a Universal GSM. | It is not a standard tractor feed, so it would require quite a bit of ingenuity. | Does anyone out there know of someone who designs and bui

Al, In general, I would agree with Justin, i.e. contact printing with a 0.007" stencil is great for 0603 - 1206 size components. However, we also place 0.025" pitch QFP components. We use a 0.006" laser cut stencil and I have found through trial an

Please be carefull handling these mechanical "foil only" systems. Many people have recieved serious cuts from the razor like foils. People to be concerned about include the reciever who takes it out of the box, the technician who has to mount it in a
