## Overview

Kester RF741 is a high-viscosity, no-clean electronics rework flux in a 6cc syringe designed for precision BGA and QFP repairs. Featuring 18 gauge dispensing tips, it offers controlled application with minimal residue. Lead-free and RoHS compliant, it ensures environmentally responsible soldering with excellent thermal stability and compatibility across most no-clean solders.

## Description

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.

Review: This is good stuff - 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.
Review: Good for emitter swapping on flashlights - Works well for flashlights. That's all I use it for so I can't speak to how well it works for other things.

## Questions & Answers

**Q: hi again, would this be friendly-same with-to the kester 245 flux core ? thanks**
A: Hi I’m no expert at all but from my experience and for the purposes that I use it for yes it is very much like the 245 cored flux. To be honest this is one of if not my favorite flux all one needs is just a tiny amount and it wets up very good. It’s a great product.

**Q: Tekline trf741 or kester or am i confused about something? kind of new to soldering hope you can clear up my confusion. thanks**
A: Depends on what you are soldering.  If it's simple point-to-point or through-hole, you probably won't need anything more than rosen-core solder (YMMV).  If you're doing SMD, then a tacky flux is good.

My preferred tack flux is SRA's TF5000.  As per the MSDS, it has less toxic chemicals in it than does Kester.

### ⭐⭐⭐⭐⭐ Ain't nobody got time for that!
*by R***Y on July 20, 2020*

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!
