It offers excellent fluidity and moderate viscosity to reduce surface tension, enhancing solder wetting and penetration. Ideal for BGA, PCB, PGA, and SMD applications, it minimizes residue and smoke while protecting components from oxidation, ensuring strong, bright, and reliable solder joints every time. ## Description Product Description Gruiqrd No-Clean Flux Electronic SMD Soldering Flux Solder Paste for CPU/PCB/SMD/IC/BGA Solder (40ml ) Advantage 1. Made of acid-free, lead-free flux paste that does not empty easily. Rosin solder paste, high purity, good helper for repair and welding, non-toxic, non-corrosive, non-irritating, safe to use. 2. It can prevent the oxidation of tin, maintain the metallic luster of the tin, and the solder joints are bright and complete. 3. It has a strong deoxidizing effect on gold-copper alloys and wire wire substrates. Application It is suitable for cleaning soldering iron tips, mobile phones, SMD electronic soldering, PCB electronic soldering, BGA repairs and other precise electronic flux soldering at the chip level. Widely used for BGA The flux covers the surface of the substrate and solder and allows for uniform heat transfer/reaction of the activator with the ionic state of the oxide on the surface of the substrate, controlling oxidation and improving the quality of the solder joint Oxidation to remove function The flux removes oxides from the soldering surface, prevents the reoxidation of the solder and soldering surface during soldering and reduces the surface tension of the solder Non-corrosive/lead-free solder paste Non-corrosive for IC and PCB, easy to solder, quick to clean. Rosin has low corrosivity and is neutral and does not corrode circuit components and soldering iron tips Review: Good solder - Seems to work well, causing the solder to flow nicely. The smaller syringe and choice of tips makes using it much easier. It would have been nice to include a couple of silicon caps to seal off the needle when not in use. Fortunately I had some of these already. Review: Goes a long way - Top notch stuff, helps create impeccable clean soldering joints, especially effective for mounting SMD chips with closely spaced pins. This tube will last for many hundreds of joints. ## Features - Causes serious eye damage. - May cause an allergic skin reaction. - What you get with the flux paste package: 1 x 40 ml Rosin soldering paste Flux, and the accessorries - Composition and application: 40 ml Rosin solder paste flux, made of no acid, lead-free, no clean, solder fluid paste, which is not easy to dispose of. White paste, good fluidity, moderate viscosity, less residue, less smoke, suitable for PCB, BGA and PGA and other SMD ball array solder joints rework and ball patching - How to use electronics flux: wipe the electronic components and their circuit board clean before soldering, press the right amount of flux on the surface of the components or wire, heat the soldering iron to 100 ℃ or more, and then the tin will be melted in the solder. After adding flux, it is very easy to put on the tin, and the structure of the solder joint is very full, strong and bright - Oxidation to remove function: soldering flux is a kind of chemical substances to promote soldering, have the surface of the soldering material oil to remove oil, remove the oxide layer, increase the role of the soldering surface. Addtional The additional function of the flux to protect components and prevent reoxidation. Flux is an indispensable auxiliary material when soldering and repairing to achieve better soldering and repair results - Reduce surface tension to increase wetting force: the main function of the solder paste is to reduce the surface tension resulting from the contact between the solder and the metal of the pencil to increase the wetting force of the surface and improve the penetration of the organic activator, which is the key role of the flow. River paste is fine and white with very little deficiency and can achieve the performance of No Clean ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Gruiqrd | | Part Number | GRU-01235 | | Package Dimensions | 16.6 x 9.4 x 3.8 cm; 60 g | | Item model number | GRU-01 | | Power Source | DC | | Included Components | Flux Soldering | | Batteries included? | No | | Batteries Required? | No | | Item Weight | 60 g | ## Images ![Flux Soldering, 40 ml Lead-Free Solder Flux Paste, No Clean Rosin Soldering Paste Flux for BGA LED PCB SMD Electronics Soldering - Image 1](https://m.media-amazon.com/images/I/71aegUNATlL.jpg) ![Flux Soldering, 40 ml Lead-Free Solder Flux Paste, No Clean Rosin Soldering Paste Flux for BGA LED PCB SMD Electronics Soldering - Image 2](https://m.media-amazon.com/images/I/71NhvNyP8QL.jpg) ![Flux Soldering, 40 ml Lead-Free Solder Flux Paste, No Clean Rosin Soldering Paste Flux for BGA LED PCB SMD Electronics Soldering - Image 3](https://m.media-amazon.com/images/I/81W0dI14a8L.jpg) ![Flux Soldering, 40 ml Lead-Free Solder Flux Paste, No Clean Rosin Soldering Paste Flux for BGA LED PCB SMD Electronics Soldering - Image 4](https://m.media-amazon.com/images/I/81SHUUBlqWL.jpg) ![Flux Soldering, 40 ml Lead-Free Solder Flux Paste, No Clean Rosin Soldering Paste Flux for BGA LED PCB SMD Electronics Soldering - Image 5](https://m.media-amazon.com/images/I/71TBLeSGvwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good solder *by N***K on 30 January 2026* Seems to work well, causing the solder to flow nicely. The smaller syringe and choice of tips makes using it much easier. It would have been nice to include a couple of silicon caps to seal off the needle when not in use. Fortunately I had some of these already. ### ⭐⭐⭐⭐⭐ Goes a long way *by D***Y on 9 June 2025* Top notch stuff, helps create impeccable clean soldering joints, especially effective for mounting SMD chips with closely spaced pins. This tube will last for many hundreds of joints. ### ⭐⭐⭐⭐ Simple and effective *by P***T on 28 February 2025* New to soldering looking for particular products and got this item for the flux side of life. Found the larger syringe was effective for depositing flux into the smaller syringe. But the smaller syringe continued dropping flux well after compressing the plunger. But beyond that it does the job required --- ## 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.hr/products/642387136-flux-soldering-40-ml-lead-free-solder-flux-paste-no](https://www.desertcart.hr/products/642387136-flux-soldering-40-ml-lead-free-solder-flux-paste-no) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-20*
