Good value too. ### ⭐⭐⭐⭐⭐ Superior Quality Flux for Enhanced Soldering *by T***R on 27 February 2025* This Soldering Flux Liquid RF800 has really made a difference in my soldering projects. The quality is excellent, and it makes the soldering process smoother and more reliable. My joints are much cleaner and stronger thanks to this flux—definitely a must-have for anyone serious about electronics work. ### ⭐⭐⭐⭐ Good value for money *by A***R on 27 April 2024* I have found this flux to be pretty good for soldering to things like small vias or pads, or through hole components maybe not quite so good for anything bigger. I haven't tried it for any BGA rework so can't comment on that. On the plus side it is easy to apply with the brush, is clear so doesn't obscure anything and doesn't seem to leave much if any residue, although always good to clean up afterwards with some IPA. On the downside it does evaporate quickly so needs reapplying. The most annoying thing about it is how easy it is to accidently knock the bottle over, as others have noted. For the price it is very good, worth trying at least. ## Frequently Bought Together - Soldering flux Liquid 50ml oiler- SMD/RMA No Clean,Reflow, Rework, Reball RF800 - TOWOT Solder Wick Braid with Flux No-Clean Electronic, Desoldering Wick Braid Remover.Desolder Soldering 2.5mm W 0.10'' L 5' - Solder,0.8mm Solder Wire Lead Free Sn99.3 Cu0.7 with Rosin Core for Electronic Electrical Soldering Components Repair and DIY(20g) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/632464189-termopasty-soldering-flux-liquid-50ml-oiler-smd-rma-no-clean](https://www.desertcart.us/products/632464189-termopasty-soldering-flux-liquid-50ml-oiler-smd-rma-no-clean) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-08*
