Blade angle, print speed, squeegee pressure, should be used in conjenction with one another. The more parellel the blade is to the stencel the more it will tend to float over the solder and the more paste is forced thru the appature. Contrary the gre

Thanks Phil, Yes this is a Lead-free BGA. Not sure of the alloy yet. Looking into it.

If you kink the leads will you be able to insert it without flexing the board/moving any of the other components? Also these pin headers aren't always designed for this process so have you checked that it will take the elevated temperatures?

I agree with verifing this part is even high temp reflow compatible. The age of the original dwg release, 1986, and as there is no mention of high temp reflow compatibility, only a mat'l call out of nylon, leads me to think it is not.

Comments are: * Link you posted to your brush actually connects to a general catalog page. * Not sure what solders your friend was using, but pastes leave different residues that affect probing. Some are soft and gooey, others are hard and brittle.
