RF741 No-Clean Electronics Rework Flux 6cc Syringe

This is some of the best flux I've used. Makes solder flow through things that used to be a royal PITA. Note: it does seem to be more corrosive to iron tips than standard flux, but I was expecting that.

Works well for flashlights. That's all I use it for so I can't speak to how well it works for other things.

It sticks where you want it. But it's easy to squeeze out. It made using flux so much easier for me. I used to use a can and have to brush flux where I wanted it. Took a lot longer than using this. I'll never go back now. A tiny little bit is all you need. Depending on the size of your solder joint of course. Add too much and it will run down whatever you're soldering. I used to obsess about throughly cleaning a board after I solder. Now if there's a little flux left near the joint after soldering I don't sweat it. Ain't nobody got time for that!

I'm looking for a tacky flux that I can use with my desoldering gun on PCBs. Kester RF741 was recommended in one of the videos I watched, so I thought I'd start with it. Most people are selling 30cc tubes of it for approx $24, but I didn't want to spend that much on something I might not like. I then came across CML's repackaging of it in 6cc syringes with a dispenser tip. I like the convenience of a dispenser tip so I can precisely put the flux where I want it, instead of having to scoop some out of a 30cc tube with a Q-tip. *rolls eyes* I have two other fluxes ordered, and will compare the three to see which I like. Regardless, the reason I'm giving this product five stars is because of the follow-up by CML. They sent me an email after the sale, asking me to review it and if I had any problems to please reply to that email and "A REAL PERSON will respond to you as soon as possible." In this age of off-shored Customer Support, the fact that a vendor wants to insure I'm happy with the purchase is important to me. It's one of the criteria I use to determine who I'll buy from in the future. CML made a good first step with that email.

Great product. Came with a multitude of tips so you can use the needle tip for pin point precision or use the wider plastic tip for a broader application. I have used this flux now multiple times and it works great.

I use this stuff it's awesome

Great product for most types of soldering. I really like the tackyness of the flux and also that the flux stays wet for a brief moment just enough time to give that last little tweak to what ever im working on. Shipping was very fast so CML does a very good job at that. I definitely do recomend.

Burns quick, easy to dispense, way too costly.
