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". =)

What is squegee snap off and how is it measured?

Snap off is the distance from the top of the board to the bottom of the stencil.

If you're using vaccuum to hold the board, too much vacuum can cause bad print. This generally occurs during snap off. You can either decrease snap-off time of reduce vacuum.

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?

Adrian, I'll go again. The term "snap off" on it's own refers to the distance between the bottom of the stencil and the top of the pcb. Sometimes referred to as "print gap". As you prefaced your question with "squeegee snap off" I thought you were as

It is the distance between board and stencil. When your stenciling solder paste you usually want to contact print (which is "0" snapoff). When you are stenciling adhesive you can affect your dot size and quality by using a gap between board and stenc

>> try a linear ramp to allow the entire pcb to heat up evenly. What is your conveyor speed?

True, But it was a rather nice looking PC on our 6622C.... And have you considered that without a PC how could they give us all of those really helpful alarms that seem to go off every 5 mins? (really handy as you're showing customers around. "Tha
