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

A customer of mine is using Chemtronics (Circuit Works) CW3300 Overcoat pen. This is an acrylic conformal coating. It cures at Room temperature. They need something similar that can be UV cured in a pen form. Any suggestions?

How are you applying the expoxy resin? Why use the expensive pen edding aerospace pen under the epoxy when a cheaper pen will do?

Some of our troop use manual tweezers. Some use 'vacuum pens' things. Vacuum pens are manually operated, vacuum powered. Suppliers of the vacuum pens things are: * Lighter weight, lower strength ** PenVac [www.virtual-ii.com] ** Vampire ** Select

Yes, I tried to clean it, but the pen is just messed up. Somebody broke part of the tip off and that is the cause of the screw up. The pen works, but it is very picky about what parts of the screen it likes and doesnt like. I was just tired of playin
