Yes, they are fairly easy to use. Hardest part is alignment. But with a Mantis magnifier, they are not bad. They really do work! We apply the Stenquik and then squeegee paste on. Very simple, wish I invented it.

Hi Mark, Solder paste will not flow on Ni like it appears on HASL. Where you print it is where it will reflow. Has been like that for years. As a CM you should re-engineer / recut your stencil to provide proper solder joints. I seriously doubt i
