I worked on MicroFlex. All axis move via electric motor drive. Carraige reapatability is +/- 0.0005" (12 micron). Cameras position more easily on linear bearings than the swivel type. The alignment accuracy and repeatability easily supports sub-20mil

We assume the silk screen is epoxy. If so,: * Easiest: 'black-box' the undesired area by printing epoxy on top of the undesired area. You could use a stamp-pad easily. * Fairly-easy-but-messy: use a Dremmel-type tool to remove the undesired area. Thi

What tells you your screen printer is at fault?

I am writing a report about screen printing. Does anyone know where I can find information about screen printing and screen printing machines?

SPM is superior. SPM has larger print area, up to 20� x 19", vs. 17.7� x 15.7� for the UltraPrint 100. UP100 is microprocessor controlled while the SPM has a PC. The SPM cameras can be positioned more rapidly and with greater accuracy than UP100's.
