Hello All,

I will like to know if some people ever did some test with qfp's on solder
side going in the wave.

We have to do some test with 20 and 25 mils pitch at wave. I already did
some test, placing the component at 45degres with solder thief, but the
result were questionable. I saw some short. For now I did some test on just
few boards so the wave profile and parameter are not realy define. My
question will be more on faisability and shape of solder thief and also
some guideline for wave parameter.

If some people can help me I will be greatfull.

Thank you.
