It features an exclusive UV additive that allows you to detect application errors under UV light, ensuring flawless results every time. Available in a 100g container, the UV-218 is the perfect choice for BGA rework, SMD assembly, and all precision soldering tasks.

Key Features

1. UV-Enhanced Quality Control – The flux contains a special UV-additive that fluoresces under ultraviolet light, allowing you to instantly identify application errors, excess paste, or insufficient coverage during stencil printing or manual application.
2. Lead-Free & No-Clean Formula – This high-purity, lead‑free flux leaves behind only a minimal, non‑conductive, non‑corrosive residue after soldering that requires no additional cleaning, saving you valuable time. Its high insulation resistance prevents short circuits.
3. Excellent Wettability & Spreading – The flux is formulated for high‑intensity applications, providing superior surface wettability and spreading. It effectively prevents the sticking of molten solder, resulting in cleaner joints and less rework.
4. Gel Consistency for Precise Application – The smooth gel texture stays exactly where you apply it without running, making it ideal for precise dispensing on BGA pads, under SMD components, and in hard-to-reach areas. It easily spreads to ensure even coverage.
5. Non-Damaging & Non-Corrosive – The formula is completely safe for use on sensitive electronic components, PCBs, and IC chips, preserving their electrical and mechanical properties. It is non-corrosive, preventing oxidation and ensuring the long‑term reliability of your repair work.
