We got ours hooked on solderballs - 2 birds with one stone!

Do you refer to the highlight in the picture as a solderball? Looks more like copper to me.

We are launching a new product and are fairly new to reflow soldering. A concern that has arisen is a fairly consistent solder ball that forms at an electrolytic capacitor. We changed to a homebase aperture design on our passives to eliminate mid-c

Besides the processing tests (different print speeds, print delay times, etc.) one test we've had to use is humidity exposure. Solderballing due to high outside humidity is a problem in our plant. So we expose paste to 85% humidity for various time

The Solderballs are on the botton side of the board.The solderballs are concentrated around through hole edge connectors, which have a Tin/lead finish and have lead pitch of 2.5mm, on top of this, random solderballs are occuring around test points. T

| We are in the process of getting into no-clean paste and fluxes. One important issue in this is sodler balling. I have heard some people say that having a matte finish would help in having lesser solder balls and that the solder balls would not b

| We want to produce BGA�s which will be see burn in conditions | of 140�C / 24h active tested. | Now we think about problems for the solderball uniformity. | Does anybody know about problems or about special solderball | alloys for such productscon
