Its lead‑free formulation meets strict RoHS standards, ensuring safety for both your components and the environment.
Key Highlights
- Lead‑free, RoHS compliant – safe for electronics and the planet
- No‑clean formula – eliminates the need for tedious post‑solder cleaning
- Excellent wetting on copper, tin, and solder alloys
- High thermal stability – withstands 300°C+ soldering temperatures
- Low viscosity, easy to apply on circuit boards and wire connections
- Long shelf life – store at room temperature for up to 24 months
- Non‑corrosive, non‑toxic – ideal for sensitive components and medical devices
Benefits for Your Projects
- Consistent, strong solder joints with reduced risk of cold solder or bridging
- Minimal residue – keeps boards clean and ready for inspection or further assembly
- Enhanced reliability in high‑frequency and high‑temperature applications
- Time‑saving – no post‑cleaning step means faster turnaround and lower labor costs
- Versatile – suitable for hobbyist prototypes, industrial PCB production, and repair work
Application & Usage
Apply a thin, even layer of paste to the joint area using a brush, syringe, or dispensing tool. Heat the assembly to the required soldering temperature (typically 350–400 °C for most lead‑free solders). Once the solder melts, the flux activates, promoting excellent wetting and adhesion. After cooling, the residue remains harmless and does not interfere with circuit performance.
Safety & Compliance
Formulated with non‑toxic, low‑smoke ingredients, this flux paste is safe for use in cleanroom environments and complies with international safety regulations. Packaging is recyclable, and the product is free from hazardous heavy metals.
