SOLDER WIRE
Nectec’s Solder Wire combines pure tin materials with advanced antioxidant technology to deliver reliable soldering performance for diverse electronic assembly needs. Its flux-injected design ensures uniform wetting and minimal defects, while compatibility with automated/manual processes makes it suitable for high-volume manufacturing and precision repairs. With alloy options ranging from lead-free Sn-Ag-Cu (e.g., Sn96.5Ag3.0Cu0.5, 217–220°C) to traditional Sn-Pb (e.g., Sn63Pb37, 183°C), the product caters to both environmental standards and legacy applications. Backed by strict quality control, Asahi’s solder wire ensures consistent joint integrity, reduced production waste, and seamless integration into wave soldering, selective soldering, and other high-temperature processes.

Description
-
Pure Tin Composition with Minimal Waste
Crafted from high-purity tin, reducing tin slag formation during soldering to minimize material waste. This feature ensures cost efficiency and maintains a clean working environment. -
Superior Oxidation Resistance
Formulated with sufficient antioxidant materials to prevent surface oxidation, preserving solder fluidity and joint quality even in high-temperature soldering processes. -
Versatile Soldering Process Compatibility
Suitable for both automated and manual soldering, adapting to diverse production lines. Its flux-injected design ensures consistent performance across wave soldering, selective soldering, and high-temperature applications. -
Optimal Flux Distribution
Engineered with evenly distributed flux in the tin core, eliminating flux breakage and reducing smoke/spatter during welding. This results in cleaner operations and lower post-soldering maintenance. -
Bright and Robust Solder Joints
Delivers full, bright solder joints with high strength and electrical conductivity, meeting rigorous reliability standards for electronic components.
