Last I heard the Mydata MY500 jet printer was in the $275k-$325k range. If it does all they claim, I would love to have one. However, we only buy 45-50 screens each year and have only a small amount of rework due to paste errors that the MY500 woul

not just speed, looking to reduce down time on having to re-do boards from bad stencil screening. also, the accuracy of placing solder paste down on PCB's. why would you want an employee spending so much time aligning fiducial marks from panel to pan
