Electronic paste flux is a soldering flux in paste form, specially designed to improve the quality and reliability of electronic soldering, particularly during SMD / SMD assembly and rework.

---

It provides excellent wetting of the tin, prevents surface oxidation during heating, and makes it easier to produce clean, shiny, long-lasting solder joints.

This flux paste is ideal for manual soldering, repair and rework operations on printed circuits.
Its paste-like texture ensures precise, drip-free application, even on fine-pitch components (QFN, TQFP, BGA, SMD).

Unlike solder paste, it contains no tin: it acts solely as a chemical activating and protective agent, guaranteeing perfect adhesion of the solder.
