Kester83-1000-0951 951 Soldering Flux Pen Low-Solids, No-Clean 10Ml

We use these a lot for our hand production. They work well and dispense about the right amount of flux. The flux stays clear and is hard to see when dry on the PCB.You can press down on the tip to get a faster flow. You must be diligent about putting the top back on tightly or it will get dried out. They will last for months after opening if you jam the top back on.I like these better than the competitor we've used before (don't remember the brand)

Are you, like me, a builder? If you work on electronics kits like ham radio equipment sometimes you need flux to complete a join. This will do the job for you.73

thank.

worked great and fast shipper and i like pocket pen carry option ,only downt in t amounhe right side i think mine wasent tube

This is the best flux I've ever used. Makes hand soldering of SMT parts very easy, and leaves very little residue. I usually clean up after with rubbing alcohol, and it cleans very easily.I do a lot of soldering but this pen lasts a while.

This is a very easy to use way to apply flux. I use it for building and repairing quad copters and it makes soldering a lot easier.

Good no clean pen made by a reputable company (Kester). My pen had a recent date code and the flux flows out of it nicely after you press the tip in a few times on something firm. Very satisfied for seven bucks.UPDATE: Flux no longer flowing out nicely. Have to really press it hard on something and still doesn't flow heavily like it should be. Good flux, bad pen design or something.

This is a great way to apply flux on a PCB. Gently press the felt tip of the pen against the surface and it will go inside the shaft producing a tiny pool of flux on the board. You don't have to press hard or stay too long. Then use the felt tip to spread the flux over the points you want it! Kudos to Kester for this great product!
