Premium SN63 1.2mm Lead Tin Solder Wire

Professional SN63 1.2mm Solder Wire for PCB and Electronics Work

SN63 1.2mm solder wire is a high-performance lead-tin soldering wire designed for electronics repair, PCB assembly, circuit prototyping, and DIY engineering projects. Made with a precise 63% tin and 37% lead alloy composition, this solder wire delivers stable melting performance, excellent conductivity, and durable solder joints for professional and hobby-level applications.

The eutectic SN63 alloy melts smoothly at approximately 183°C, reducing cold joints and improving soldering accuracy during delicate electronic work. Its built-in rosin no-clean flux core helps remove oxidation while creating clean and reliable solder connections. Whether you are repairing mobile devices, assembling Arduino circuits, working on robotics systems, or maintaining electrical components, this solder wire provides consistent and efficient performance.

In Bangladesh and BD electronics communities, SN63 solder wire is widely used for science projects, repair workshops, engineering labs, and educational prototyping. Many students and makers from Biggan Project and DIY electronics enthusiasts prefer this type of solder wire for stable PCB soldering and long-lasting electrical connections.

The 1.2mm diameter offers balanced solder flow, making it suitable for both medium-sized components and general electronics work. It is compatible with common soldering irons ranging from 15W to 40W, making it convenient for beginners as well as experienced technicians in Bangladesh.
