Chemistries are limited for WS Mask. Try looking/changing other components, trying different flux types is easy, identify water cleanliness, is it ionic/no-ionic...probably is benign. Could be a plating reaction which is tough to investigate. Call

Check if the feeder position is out of picking area mentioned in manual. Change the feeder position.

You're correct, CPH doesn't mean dip. You want: * Perfect parts. * On-time delivery. * Cpk ~2 each quarter * Zero lost machine time as a result of product change-over. ... Right?

the voids will cause a long term relability problem as the part will not be correctly heatsinked. Change your stencil aperature to a "+" sign 15-20 mils wide in the center of the pad. ___________ : | : : | : :----|----: : | : :__

I have a Dynapace 400 series conveyor. How do I make it change direction? Is Dynapace still in business? Thanks for any info you may have.

I did. Nothing change. I can go in mount feed back and increase .5mm for all rotations(Lazer mount feed back), then it work. But all my parts go to camera will be off the oposite way.
