Sn63 solder is a type of alloy that is composed of 63% tin and 37% lead. Tin has a low melting point, good electrical conductivity, and low toxicity, making it a popular choice for soldering. Lead, on the other hand, has a high melting point and is less expensive than tin. The combination of tin and lead in Sn63 soldering lead results in a solder with a melting point of 183°C, making it suitable for use in low temperature applications. Read More
