We changed paste manufacturers rather recently and are now seeing SOT23s falling off after wave solder. These parts have a dual process... we stencil print paste, apply glue, populate then reflow. Only SOT23s fall off, chips are fine. We do not be

I am printing a ceramic paste through a 160 mesh screen that should have a theoretical wet print thickness of 53um but the only way I can get the print that thin is to increase down stop and slow the stroke. This is causing problems with the mesh, s

Chrys Shea has published extensively on stencil materials, coatings and paste release mechanisms. Many of the papers are available to download on her website. Just search for Shea Engineering Services. I've worked with Chrys in the past, she is defin
