My company has been doing its hand soldering using drip bottles for application of no-clean flux. This has created quite a few problems, especially on our microwave boards. I want to convert us over to flux pens. Does anyone have any suggestions or c

Using a flux pen sounds like a good idea. Comments are: * I assume you�re talking aqueous flux. If not, some NC flux pens leave white residues. Nearly all of 15 samples suffered to varying degrees with white residues. * Use the same flux that you

Your research is on track. NC flux needs to reach activation temperature. Also, do not depend on the corrosion characteristics associated with the flux classification (ie, L1, L0, M1, M0, etc.), until the flux is activated by exposure to soldering

We use NC flux exclusively for SMT and wave soldering. And it is a fairly old formula from Multicore, though we are currently qualifying a new formula. The automated soldering does not appear to be a problem. It is only the hand soldering that causes

Yanno, I just thought of an addition to #3 above. Back in the ol' days (before computer drawing) there were rooms full of people, generally guys (with plastic pocket protectors holding colored pens and ... ) leaning on drawing boards, doing whatever

Hi Everybody, In our process we use syring flux for repair the boards, both SMT and PTH. I would like to know with your experiences what kind of flux is better for SMT and PTH repair, PEN or Syring flux??

For some, not all, hand assembly, we use additional flux. We use a flux pen in certain applications and liquid flux in other applications - you can't just say switch to a flux pen, it isn't always adequate. Most flux pens are ORL0 with very low sol

Hi Adam, Excessive heat from soldering iron will left the burn mark of RMA flux. The residue is hard to remove. Suggest to use the Flux pen for better control.

Questions are: * Are these lint-free rags ESD-protected? * How do these lint-free rags remove the flux that seeps under components? * Have you considered flux pens as an alternative to your current process?

Sorry for being late on the reply. Whatever you do, flux from the container or the manufacturers flux pens. Stick witht the same chemistry. Mixing chemistries, IE: different fluxes will create more problems in rework than you will see if you use the
