wave soldering and solder bridge

Electronics Forum | Mon Dec 17 10:46:04 EST 2007 | realchunks

First of all, more info is needed. Solder shorts can be caused by much more than flux. Is the solder short always in the same spot or all over the place? More detail please.

Soldering robot and solder balls

Electronics Forum | Tue Jun 20 15:08:30 EDT 2017 | ranap121212

Hello I have the problem with selective soldering on the robot. Thin balls appear on the laminate. The tin sometimes shoots...? and then the balls are a few millimeters from the soldering point. I tried up or down with temperature, but it did not wor

This is funny. Poeple giving answers to a question that isn't specific. What if the shorts he is having are on the top of his board, caused by flooding or Omega wave too high?

Palladium finish and solder balls

Hi there. We have had an out of control reflow oven that has allowed its temperature to fluctuate by up to +/- 20 deg C from set point in very short periods of time. We found the root cause of the problem and fixed it, but by then we had already run

I made my own wave measuring device using KIC2000 system. KIC2000 has automatic wave detection, so now I have a profiler for both reflow ovens and wave solder. The delmat carrier only cost $500. A guy, Samir, from this forum gave me the idea, actu

As someone with a LOT of experience with the "low cost" alternative alloys, primarily SACX, I have one simple question....Are these shorts a new phenomena? WAS your process in control, and all of a sudden it's not? If the answer is YES, take a look a

No solder and solder bridge after Wave solder machine

Electronics Forum | Thu Nov 17 21:46:48 EST 2005 | C. Kolokoy

With DIP type components, a sub-par fluxing method (foaming a no-clean), and a chip wave where one is not needed are formulas for bridging and insufficient wetting. If you have SMD's on the wave solder side of the board greater than 0603, and no SOT

Evalution on solder paste and spray flux

Electronics Forum | Thu Jan 27 11:23:45 EST 2005 | russ

Well first off I wouldn't evaluate paste for a wave process. I would use solder bar instead. Flux - top side fillets and no shorting on the solder side, does it clean well after processing if using water soluble flux. How wide is the process win

Selective soldering pallets and solder balls

Electronics Forum | Thu Dec 05 11:04:27 EST 2002 | slthomas

They're IR, bottom side only. Frankly wave solder is not my forte (there are those that would claim nothing is), but I've personally been tasked with developing a process to do reliable, high volume bottom side SMT, so I'm drawing a lot from the tec

solderability and hasl thickness

Electronics Forum | Thu Sep 11 16:50:18 EDT 2003 | davef

Sure it's conceivable that thin HASL can cause tombstoning. Harkening back to the ample discussion in the fine SMTnet Archives, tombstoning is caused by an imbalance in solder surface tension between the two pads of SMT component. The source of thi
