In the world of electronics and industrial manufacturing, precision, reliability, and quality are paramount. For over six years, Pratibha Technologies, under the brand name Pratibha Solder, has been delivering top-notch soldering solutions tailored to meet customer requirements. Utilizing state-of-the-art plants and machinery, combined with carefully sourced authentic raw materials, Pratibha Technologies ensures that every product, including the highly sought-after 63Sn-37Pb leaded solder wire, meets the highest standards of performance and consistency.
Whether you are a professional PCB assembler, an electrical repair specialist, or an industrial manufacturer, our 63Sn-37Pb solder wire provides flawless joints, superior conductivity, and unmatched reliability.
The 63Sn-37Pb leaded solder wire is a eutectic alloy, meaning it melts and solidifies at a single, precise temperature of 183°C. Comprising 63% Tin (Sn) and 37% Lead (Pb), this alloy ensures clean, defect-free solder joints every time.
Unlike other solder alloys, 63Sn-37Pb does not pass through a pasty phase, which minimizes common soldering issues such as cold joints or solder bridging. This makes it a preferred choice for PCB assembly, electronics repair, and industrial wiring.
