2) Open time: A 15-minute queue between paste, place, and reflow SB fine, assuming humidity is not too great. 3) Wash temperature: Yes. A wash temperature of 130-140�F SB fine. 4) Reflowed board was left too long prior wash: Are you washing: * After

In a LARGE degree, the residues being cleaned dictate the selection of an effective saponifier. Your washer supplier may be a good source of suggestions. Many saponifiers present potential VOC issues, because of their use of alcohol. Try: Kyzen Aq

Excess slump of paste and mis-registration can cause solder balls along with moisture. Use same date code of pcb and run with no components, paste only. Also pre-bake boards with humidity sensor in oven. If high humidity, moisture and solvent residue

Sure do, it's from the paste that gets squeezed under your R's and C's. This paste is now on your mask and during reflow, wants to move off the mask. Unfortunatly, it follows the flux residue to the side of your component. An easy fix is to use th
