While we're unfamiliar with Swisstone, we accept: * Techspray Solder-Wik * Chemtronics Soder-Wick * NTE Solder Wick All of these [and Swisstone] look basically the same. We wonder if maybe they're all made by the same source and branded differently

hello, I have been experiencing a strange solder defect lately. hope some of you may know what is causing it. it happens on same side of processor and there has been no changes in soldering process.

Do you have clear pictures show IC soldering and the solder ball? DO you have clear picture show the PCB pad?

These new inline washers are cleaning so great now. There will be no flux to hold these solder balls at all. However, experts here might help you to get rid of the solder balls in process. so you don't have to clean.

Q1 Can anyone explain to me what is the clean and non clean solder? A1 The trend away from CFCs has lead many users to evaluate switching to no-clean soldering processes. The term "no-clean" is actually a common misnomer when used to describe a flux

If the world was a perfect place, I would recommend preventing solder balls in the first place. While low amounts of solder balls are common, a high volume of solder balls are problematic to a cleaning machine (batch or inline). Solder balls may beco

Sn62Pb36Ag2 has a higher liquidus point of 189C as compared to Sn63Pb37 at 183C. You may need to slightly adjust your oven profiles to use it compared to SnPb. We have had good solder-ability and reliability with it in our IPC Class II products. A

No argument here. But I've don't think I've ever seen solder balls on 0402s. Even when they're placed on narrow G dimension pads, where there is little toe fillet, I've never seen a solder ball. But your idea of reversed homeplates would work grea

I am having cleaning problems when processing PCB's which have TAIYO solder mask on them. After processing, hand soldering and cleaning, a sticky residue is remains, resulting in a cosmetically poor finish with tide marks etc. Other soldermasks do no

Has anybody heard about solder wires for rework with a V-notch in order to avoid solder balls which might be caused by shooting flux when getting hot. The notch is as deep to reach the core so that the flux can expand easily. I can imagine the effect
