Can you verify that the process is in control using SPC? Can you use the SPC results to reduce or eliminate the frequency of inspection? Blair Hogg QA Manager GAI-Tronics Corporation >>> [log in to unmask] 12/30/03 01:43PM >>> Hi Tom! Yes, and those systems aren't that cheap either! Let me just throw this question out to everybody; let's assume that the stencil has been ordered correctly (correct thickness for the type and pitch of the components being placed), the printer has been set-up correctly (correct squeegee speed, pressure, and separation speed, along with proper board support), is there REALLY any value added, or will things vary THAT much when using METAL squeegee blades, that thickness measurements need to be done every 25 boards or whatever, during a run? I have my own opinion, and experiences about this...but I would like to hear what everybody else thinks. -Steve Gregory- > Use ASC212 for solder paste thickness and volume.
