JIAJINYUAN no-clean leaded solder wire is produced by melting high-purity tin and electrolytic lead at the Sn55Pb45 ratio, refining to remove impurities, casting into tin rods, injecting a low-residue no-clean rosin flux under hydraulic pressure, and drawing to the required wire diameter. Its core value lies in extremely low, transparent residue, low ionic contamination and high insulation resistance, widely used in no-clean processes for consumer electronics, household appliances, instrumentation and automotive electronics, eliminating downstream cleaning and saving cost.
The product uses Sn55Pb45 alloy with a self-developed low-residue no-clean flux formula; flux is uniformly and continuously filled into the center of the tin alloy, and rosin content, wire diameter and packaging can all be customized to the customer's soldering process.
It passes authoritative SGS testing and meets relevant environmental directives in the application field (lead-containing products are used under customer-process and local-regulatory exemption clauses).
Solder feeds smoothly without breaking, with solder climbing height up to 100% and bright, full joints. It effectively solves industry challenges such as cold joints, solder bridging, solder balls, tombstoning, and voids.
Certified to multiple environmental SGS standards including RoHS, halogen, and REACH (SVHC). Post-solder residue is transparent and colorless, ROL0 no-clean, with high insulation resistance for safe, reliable performance.
Advanced production and testing equipment from Germany and Japan, strict ISO9001/ISO14001 quality control, and 21 inspection steps per batch ensure consistent, stable performance over the long term.
Our experienced engineers provide one-on-one service, free on-site debugging, and better-matched solder wire products, solving soldering process issues on the spot.

Free Technical Consultation18 years of craftsmanship — every detail is a promise of quality
Advanced production and German testing equipment, strict ISO9001/ISO14001 quality control, and 21 inspection steps per batch ensure consistent, stable performance over the long term. Low fume, no unpleasant odor, and free of volatile gases harmful to health; no rosin splatter, transparent and non-discoloring rosin residue, and high insulation resistance.
Strictly compliant with national standards and made from high-purity virgin tin, electrolytic copper, and pure silver. Rich in main elements with very few impurities, the wire has a bright surface and produces bright, strong, reliable joints. Precise process control ensures uniformly and continuously distributed rosin flux with no core breakage for consistent joints; uniform outer diameter and neat, smooth winding that will not tangle or block the guide tube during automated soldering.
Our independently developed flux removes the oxide layer and surface oil from the soldered material, lowers its surface tension, enlarges the soldering area, and delivers good wettability, fast tinning, with no peaks or bridging.
A scientific rosin flux formula produced in strict accordance with national and EU standards ensures excellent solderability while keeping flux corrosiveness low, iron dross minimal, residue low, and cleaning unnecessary.
Precise winding technology keeps the wire flat and tangle-free, making it convenient for automated soldering equipment, effectively improving production efficiency and reducing waste.
