Well gasketing yes, have you dine enough analysis to blame aperture design- Maybe not? Maybe whip out the gerber files for this PCB&stencil and compare the details with one you feel works well. Is there something different about their layout rules o

A lot of MELF components have solder ends that stand slightly proud of the main body where your vacuum would lift them, so vacuum leaks are most likely the culprit. Upping the Vacuum to the nozzle may help, but better thing would be to modify the noz

Do it all the time. With an automatic printer you would have your two images at opposite edges of the stencil and to switch between them you would remove the stencil and rotate it so the one you want is at the front. Naturally you need to make sure t

Is your stencil worn out? If your once flat stencil is now wavey, you will be depositing more paste. Ideally, you'll have historic SPI data to compare known good volumes from past prints to the current. Another possibility is moisture. Bake your boa
