Lower Soldering Temperature. Higher Production Reliability.
For manufacturers of transformers and magnetic components, soldering performance directly affects production efficiency, product consistency, and long-term reliability. Conventional solderable magnet wire often requires high soldering temperatures, increasing energy consumption while exposing bobbins and magnetic components to excessive thermal stress.
HUAYE developed a Low-Temperature Solderable Enameled Copper Wire that enables reliable soldering at significantly lower temperatures, delivering a more stable and cost-effective manufacturing process.
Customer Challenge
The customer experienced several production issues with their existing magnet wire, including:
--Soldering temperatures approaching 430°C
--Incomplete solderability after repeated soldering cycles
--Solder bead formation affecting product quality
--High bobbin deformation caused by excessive heat
These challenges reduced manufacturing efficiency and increased overall production costs.

HUAYE Solution
HUAYE optimized both the enamel formulation and production process to achieve excellent low-temperature solderability while maintaining outstanding thermal resistance.
