SQUEEGEE snap off is the gap between the top of the stencil and the the bottom of the squeegee blades. You can measure it with a set of feeler gauges.

I thought the stencil was flush to the top of the board when Screen printing. When does this snap off occur in the screen printing process?

Hi Adrian, If you do a "squeegee snap off" during solder paste printing...the result would be a very thick solder paste deposition. I think the correct term is stencil snap off or people say it "snap off distance". =)

I've been using metal blades on several brands of printers over the past few years and have to agree with comments in other replies. Contact print is a must or you will tear slits in your stencils at the ends of the blade. Center-mounted (floating) s

Hey Dave, We have had problems with low RH. In a very short amount of time, the paste dries out and starts to stick to the squeege blades. We would see an increase in skips and some clogged appertures. This has only happened when the RH was 15% or b

Paul, We are applying the paste flux to the bga. We have a plate that has a 4mil step that we squeege flat and then dip the BGA into the flux.The BGA's that we are using are new components.

Squeege speeds can vary from .5 in/min to 6-8 in/min. It really depends on what the prints look like. For ultra fine pitch I usually start at .8 in/min and take it from there.

If a rubber squeege is bumped on the edge, no biggee. But you have to be carefull the metal ones don't get dinged. All it takes is a little extra care but if your operators are used to handling the rubber one they might not increase the amount of c

What exactly do you mean by "side clamps"? If you mean the thin strips of metal that the board is pushed up against, they are adjustable. Maybe a little more squeege force or down stop also.
