Kester part number 24-6337-8806 is a eutectic Sn63Pb37 solder wire with 0.015 inch diameter and 1.1% 245 rosin activated flux, purpose built for precision work on printed circuit boards, electronics rework, and through hole soldering where fine control and minimal residue are required. The eutectic composition melts and solidifies at 183°C (361°F), making it ideal for temperature sensitive components and applications demanding consistent, repeatable joints. The 245 no clean flux is formulated to remain on the board after soldering, reducing the need for post solder cleaning while maintaining electrical integrity and appearance. This is a trusted professional choice for technicians and repair shops who depend on predictable performance and reliable sourcing from a proven manufacturer.
