Hi to everyone, I will be runnig product with adhesive with a MPM UP2K, I'll use a 0.020" stepped stencil & metal blades. Is it better to use high speed for print head travel? more/less squeegee force than with solder? slow snap off? what could you recommend me?

Thanx

The choice of adhesive is driven primarily by the mix of component types on the board. * Passive components => dots of minimal height. So, use a lower viscosity adhesive. * Higher standoff components => larger (and taller) dots. So, use a high viscosity [typically, also high yield point] adhesive.

I am printing on DEKs and using simulara paramateres as for a solder it works really fine. In general going faster gives you more paste/glue. Less pressure gives you more paste/glue again. All the rest depends on your current board.

Ok, thanks for the info, fortunatelly we already have our Camalot glue dispenser machine In-line with our MPM, for helping whit the high stand-off components.
