Product Description

Sn99.3 Cu0.7 Introduction

The solder was produced in the first smelt of tin and copper. The use of a continuous casting process ensures minimization of the generation of oxides in the solder. As a result, the phenomenon of the formation of dross in the soldering process is significantly reduced. The composition of the solder complies with the ISO 9453:2014 standard. The solder alloy intended for mechanized soldering in electronics, electrical engineering and other industrial applications where meeting the requirements of the RoHS2 Directive is required.

Lead-free Solder Wire Introduction

Lead-free solder wire is an environmentally friendly welding material mainly composed of tin, silver, copper (Sn-Ag-Cu, SAC), without lead (Pb) or harmful substances. It complies with RoHS and international environmental protection standards, widely used in electronics, PCB assembly, home appliances, automotive electronics and precision instruments.It features low melting point, stable welding, good fluidity, bright solder joints, high strength, excellent electrical conductivity and thermal conductivity, as well as low spattering and less residue. With consistent diameter and stable flux core, it ensures reliable, long‑lasting solder connections and meets modern industrial requirements for safety, environmental protection and high performance.
