Delivered in a precision syringe with a piston injection needle, it offers smooth, waste-free application ideal for sensitive electronic components like BGA, LED, and SMD. Its high-activity flux ensures excellent solderability and bright, strong joints without the risks of high-heat damage, making it the go-to solution for professional-grade repairs on heat-sensitive devices. ## Description Syringe Soldering Paste Flux Review: Works great for soldering white metal fittings - Works great for soldering white metal fittings Review: Super 👍 - Super 👍 ## Features - Gruiqrd Solder paste content: alloy tin 42% Bi58%, flux content: 10.5%. Total weight: 50 g, net weight of the paste: 40 g - High solderability: A powerful thixotropic agent is added to the solder to make the solder paste highly active. During the soldering process, the solder is significantly moistened, reducing the phenomenon of missoldering - Lead-free solder paste: no cleaning, strong viscosity, bright welding point. Medium temperature soldering paste with flux, melting point: 138°C (280F) - PRODUCT ADVANTAGES Push design for more smooth flowing, no waste when welding. Piston injection needle features: reflow soldering does not produce tin beads and tin bridges - Applications Low temperature tin is widely used in the repair of electronic products. Low temperature tin is mainly used for items that cannot withstand the high temperature of the device. For example, electronic components that do not withstand high temperatures, LED soldering, PCB BGA CPU SMD maintenance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CZN5H8M8 | | ASIN | B0CZN5H8M8 | | Batteries Required? | No | | Best Sellers Rank | #104,351 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #213 in Solder, Solder Fluxes & Pastes | | Customer Reviews | 4.5 4.5 out of 5 stars (257) | | Customer reviews | 4.5 4.5 out of 5 stars (257) | | Date First Available | 1 June 2024 | | Date First Available | 1 June 2024 | | Included components | Syringe Soldering Paste Flux | | Item Weight | 50 g | | Item model number | GR-401 | | Item model number | GR-401 | | Manufacturer | Gruiqrd | | Manufacturer | Gruiqrd | | Package Dimensions | 14.4 x 7.4 x 2.7 cm; 50 g | | Package Dimensions | 14.4 x 7.4 x 2.7 cm; 50 g | | Part number | GR-401 | | Power source type | DC | ## Images ![Syringe Soldering Paste, Soldering Paste Sn42Bi58, Lead-Free Low Temperature 138°C, 40g - Image 1](https://m.media-amazon.com/images/I/612c7LLRRML.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great for soldering white metal fittings *by G***N on 24 August 2026* Works great for soldering white metal fittings ### ⭐⭐⭐⭐⭐ Super 👍 *by M***I on 15 August 2026* Super 👍 ### ⭐⭐⭐⭐⭐ Flussmittel *by P***R on 18 July 2026* Funktioniert Top ## Frequently Bought Together - Gruiqrd 40g Solder Tin Paste with Syringe,138°C Low Temperature Syringe Solder Paste, Sn42/Bi58 Flux Soldering Paste with 4 Needles and 1 Push Rod, Solder Paste for Bag,PCB, CPU, SMT - Soldering flux Liquid 50ml oiler- SMD/RMA No Clean,Reflow, Rework, Reball RF800 - Solder Wick, Desoldering Wick with Flux No-Clean Electronic Desoldering Copper Wire Braid Remover Desolder Soldering (Width 0.10'' Length 4.92') --- ## 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.com.ar/products/685715961-syringe-soldering-paste-soldering-paste-sn42bi58-lead-free-low-temperature](https://www.desertcart.com.ar/products/685715961-syringe-soldering-paste-soldering-paste-sn42bi58-lead-free-low-temperature) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-06*
