Description
The Relife RL-423 UV Liquid Soldering Flux (10ml) is a high-performance, professional-grade flux designed specifically for precision electronics repair, including PCB, BGA, SMD, and mobile phone motherboard maintenance. Formulated with advanced UV-curing technology, this premium soldering flux ensures clean, strong, and reliable solder joints while minimizing residue and oxidation. Whether you?re a professional technician or an electronics hobbyist, the RL-423 delivers the precision and control you need for demanding micro-soldering work.
This flux is ideal for reballing, chip replacement, and reflow soldering tasks where high accuracy and consistent results are essential. Its unique UV liquid formulation provides excellent wetting properties and superior adhesion, allowing solder to flow smoothly onto pads and components without bridging or spattering. The low-viscosity texture enables easy application using a needle tip or precision brush, reducing waste and ensuring clean, neat work on even the smallest circuits.
One of the standout features of the Relife RL-423 is its UV visibility, which allows technicians to inspect flux placement under UV light. This feature is especially useful during fine soldering or reballing operations, ensuring that the right amount of flux is applied exactly where it?s needed. The result is more efficient work, better heat transfer, and stronger solder connections that improve the overall reliability of your device repair.
Unlike many conventional fluxes, the RL-423 leaves minimal non-corrosive and non-conductive residue, making post-solder cleaning quick and easy. Its gentle formula protects sensitive electronic components from chemical damage and ensures compatibility with a wide range of materials, including copper, tin, gold, and nickel-plated surfaces. This makes it perfect for use in smartphone, tablet, and laptop motherboard repairs, as well as other fine electronics such as game consoles, cameras, and microcontrollers.
Each 10ml bottle of Relife RL-423 comes with a precision dispensing nozzle for controlled application and reduced waste. The compact design makes it easy to carry in a repair toolkit, and the secure cap prevents leakage or contamination when stored. With Relife?s reputation for high-quality repair tools and materials, this flux is trusted by technicians worldwide for its consistency, purity, and professional performance.
Whether you are reflowing a BGA chip, reballing a CPU, or performing delicate micro-soldering work, the Relife RL-423 UV Liquid Soldering Flux gives you the confidence to achieve clean, strong, and long-lasting solder joints every time.
