I say: �Wave flux needs to be heated to certain activation temps which won't be repeatedly achieved with a manual soldering process. Plus, you won't burn off any residual activator as you would if the board were immersed in a solder bath.� Muse say

Electrovert has a new nozzle design called UltraFill. It was designed specifically for Pb Free applications and generates about 40% less dross than the previous Lambda design. UltraFill can of course be used for Sn/Pb alloys. The name UltraFill is fo

We are having trouble with some through-hole connectors "shorting out" on a thick backplane. Preliminary research is suggesting that it may be due to excess flux, trapped under the plastic connector shell. I have done a bit of searching in the fine S

Cellular and PDA architectures employ this technology all the time. You have to be careful with your board supplier as well as with your plugging approach. Leave the via unplugged, I guarantee voids in the solder joint. That leaves us with, "how d

Just be careful on preheat. They tend to be weak on those small low cost machines. How well they work for you depends on what type of boards you plan to run. Large thick boards or high thermal mass boards will not likley run too well. Take boards to

Fixed spray head performance depends on board width. If you are looking for complete top-side hole fill, the flux penetration into the lead-hole will be more in the center and less on the ends because of the fan pattern spray. For board widths over 6

We've think that with seen solder shorts under BGAs after wave soldering the boards. In addition, it seems to be related to a certain soldermask configuration over the topside BGA vias.. THere is one vendor,A, that is applying soldermask after HASL,
