Designed for BGA and QFP repair. 6 CC syringe for convenient dispensing during electronic repairs.
TekLine TRF741 is a high-viscosity No-Clean paste flux developed for printed circuit board rework or repair. TRF741 is effective for prototype work where a small amount of flux is needed on a specific area of a board or assembly. The high viscosity flux stays in place until soldering occurs. Excellent performance in applications requiring a flux having good thermal stability such as surface mount component or repair.
It is the ideal choice for QFP or BGA rework operations. It is also well suited for use with through-hole repair operations.
Residues that remain after soldering are almost colorless, leaving a visually appealing repair. The residue is safe to be left on the assembly after soldering.

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!

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.

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.

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.
