Flux Pens

 

Anybody have any recommendations on a good flux pen? Maybe refillable? I have all kinds of flux but no flux pen. Figured I would add one or two to my kit. And best flux type for soldering with lead solder and ENIG pcbs?

Thanks,

Dave
 

I use a Kester 186 flux pen.? I've used it on lead solder (which is all I use), HASL boards (nominal Chinese made), and ENIG (used to use Oshpark, but the boards were too expensive).

Noe that this is not "no clean" which is reported to be more aggressive in its action.? I clean this with either isopropl alcohol (works mostly, leaves some residue behind because of the water), or standard flux cleaner.

I'm pleased with a MG Chemicals rosin flux pen - it's not refillable.

I use a Multicore flux pen. They are sold by RS Components.

Thanks Harvey,

? I have a bunch of the Kester 186 RMA flux but I think it is the "no clean". I may look for a refillable pen with the 186 already in it and go from there.

Thanks Roy,

? I looked at the link and they mention "hydroscopic" in "post soldering residues. I think they mean "hygroscopic" and if so, why would that be a good thing to have the residues attract moisture? Just curious. I am sure it works great.

Thanks Leon,

? So you have to order it from the UK? Does Loctite make that stuff?

RS deliver worldwide, but the shipping might be expensive outside the UK. Other distributors sell Ersin products.

I think they're trying to say the flux residue can be removed with just water instead of requiring solvent cleaning. It's equally likely that it's just a spelling error ;-)

When it runs dry, what do you have to lose? See if you can get it open without destroying it and if you can then refill it with (compatible) liquid flux. Might need a little vinyl tape to keep it closed and not leaky again or it may just press fit back together. It’s not a complex mechanism.
