Your cart is empty. Yosker flux-pen is a unique tool for rework and touch-up soldering. It allows controlled application of flux, eliminating the mess from flux bottles.
The chisel point allows for work in very confined spaces. The flux pen is ideally suited for tab assembly no-clean and surface mount rework application
because it can deliver flux to a specific area.
Youker is a Halogen-free, non-rosin organic flux pen that is specifically designed for rework of conventional and surface mount circuit board assemblies.
The extremely low solids content (2.0 percent ) and nature of the activator system results in practically no residue left on the assembly after soldering.
There are no residues to interfere with electrical testing.Yosker exhibits improved soldering performance to minimize solder bridges during rework operations.

Flux is good quality. None of my pens were low on liquid and none were dry. Good bang for your buck!

They are quite pricey, particularly as compared with alternative flux types but also with alternative flux pens. That said I don't think I'll ever use any other type of flux on SMT soldering ever again. They're brilliant, definitely a flux pen convert.

The flux is on a very fast-drying solvent, so unlike thicker gel type flux, the flux tends to boil away faster than I would like. It does work, however.I have used two pens already (one at home, one at the shop) and they have been fine so far. The fat marker-like tip is fast flowing, and does sometimes need a little bit of wiggling -- but I have not had problems with managing the flow as others have described.I think it's a good value. Definitely better to have than not have.

The cap goes on and off manually. The Flux comes out as expected.

I've used this for a while now and can say that it's quality flux given the price.

Bought a 5 pack. 3 of them the "valve" or tip totally stuck in the first use. They barely flow flux. The flux has an extremely low melting temp - If I pre-heat a board that i'm working on, the flux evaporates the second I touch the pen down. Get the name brand flux pens. I'm just going to throw these away.
