The Relife RL-421-OR BGA Flux Paste is a high-viscosity, strong-activity no-clean soldering flux formulated for PCB repair, SMT/SMD reworking, and computer and smartphone chip reballing. Formulated with pure imported rosin and high-quality resinous pasty flux, it ensures fast tinning without virtual welding while preventing pale yellow residues from forming around soldered components.

Engineered with high insulation resistance, RL-421-OR is a necessary material for repairing mobile phone mainboards, protecting delicate electronic components, and servicing CPUs and logic boards. Its low-smoke, high-purity formula runs tin quickly, making it an essential flux paste for micro-soldering, BGA/PGA chip reballing, and circuit board servicing. Packaged in a convenient 10cc syringe for precise, zero-waste application.

Key Features

1. Imported High-Purity Rosin: Pure color with no impurities, ensuring easy tinning without virtual welding.
2. High Insulation Resistance: Protects sensitive mobile phone PCBs and CPU logic board circuits during thermal rework.
3. Fast Tinning & Low Smoke: Promotes rapid tin flow while generating minimal smoke during soldering.
