Hi AJ, Thanks for the reply. I'm beginning to think that we have some issues with different expansion rates of the two pcbs. When you say you had some profile issues... Did you stay within the recommended UBLOX reflow time of 20 - 40 seconds and di

Thanks for the response. I am using mainly two brands of ovens. One is Heller and the other is a chinese brand called Fulongwin (copy of Vitronics). I see the problem in both, more severe in the Fulongwin. Both are 8 zones and a few 9 zone Hellers. I

Probably because the flux manufacturers have deemed it necessary to increase flux volume by 20 - 25% compared to Leaded this is why more is being left over. Really not convinced of this increase in volume actually does anything. Black residue will be

Thank you for the suggestions, I did change blades and we did try another printer, problem still exists and it is across several different products but only that line. One thought is aperature size since we over print for other reasons due to part d

Yes we see this also....... It is what they call "cold welding" of the solder paste to the blades...... The solder spheres actually "weld" together...... It leaves streaks on the stencil, not a clean wipe of the stencil....... We have never found
