content: I use Kester #951. It's a no clean flux and is available in the felt tip pen applicator or in bottles.You can also get it cheap on eBay (at least in the US).My opinion... I like it.

content: I prefer this pen-type of fluid flux for most rework:http://nl.farnell.com/electrolube/smf12p/flux-pen-12ml/dp/891186Works same as paint markers, so it has a valve in the tip which allows to wet the tip by pressing it gently.

content: No, no differences.Just that you'd need to clean the RMA-223

content: I like the Kester 186 flux pens...technically you don't have to clean the residue because it is non conductive and non corrosive. Sticky though

content: Home made flux, just the way you like it :-) Dissolve some colophony in IPA. A common recipe is 35g colophony for 50ml IPA.

content: Quote from: Short Circuit on July 20, 2012, 07:29:31 pmThat's what I have in my lab, too:Pros: easy to use, no clean, not too messy after a day or two when left to dry, works fine, does not smoke or smell.Cons: Dries fast as promised, but I'd like to flux all sides of an IC in one go, the solder all sides, instead of flux a side, solder it, flux a side etc. Wet, like water; sometimes more gel like structure would be better.Verdict: For me not perfect by any means, but good enough that I haven't started experimenting with other products.
