Yannick we print 60 assemblies with adhesive currently. We use Epibond (I'm sure there are other brands) an 8 mil stencil with modified dogbone apertures. Alpha Metals has a good aperture design booklet available. We use metal squeegees and print speed is a little slower. Glue height can be adjusted with snapoff or depending on component sizes the stencil thickness can be increased. Electrolytics and high profile IC's require more glue height. Rich can give you more information on the booklet and aperture selections. We have our own files for different type components.

And it's time consuming to get the glue off the board. Now we are thinking to print adhesive with a stencil. What do I need to do that? what type of stencil, squeegees, aperture for the component, how much adhesive must I have on the board, thickness of the stencil, in other wordswhat do I need to know to do this opertaion.
