The ZJ-18 is a professional-grade, environmentally friendly soldering flux paste designed for precision electronics assembly and repair. Featuring a neutral pH (7±0.3) and a no-clean formula, this rosin-based flux provides excellent solderability without corrosive residues. Housed in a compact 80g container, it's the ideal choice for mobile phone repair technicians, PCB assemblers, and electronics hobbyists who demand reliable, high-quality results for all types of soldering work.

Key Features

1. Neutral pH (7±0.3) & Non-Corrosive – The balanced, neutral pH formula ensures it is entirely safe for sensitive electronic components, including integrated circuits (ICs) and printed circuit boards (PCBs), preventing any risk of long-term corrosion or damage.
2. No-Clean Formulation – The advanced no-clean formula leaves behind minimal, non-conductive, and non-corrosive residues after soldering. This high-purity composition eliminates the need for post-soldering cleaning in the majority of cases, saving you valuable time and effort on each project.
3. Excellent Solderability & Wetting – Formulated for high-quality surface mount technology (SMT) assembly, it significantly improves solder joint quality and adhesion. It provides strong, durable, and reliable electrical and mechanical connections.
4. High Purity & Long Shelf Life – The high-purity components ensure that the paste will not deteriorate, dry out, or degrade over time, offering a long shelf life and consistent performance whenever you need it.
5. Environmentally Friendly – This advanced quality paste is lead-free, halogen-free, non-toxic, and RoHS compliant, making it a safe and eco-friendly choice for all your soldering projects.
