60/40 Vs 63/37 Solder – What are their Similarities and Differences
- Both 60/40 and 63/37 solder are widely used in electronics for creating connections on printed circuit boards (PCBs). They have similar compositions, consisting of tin and lead, with tin being the primary component.
- Both solder types have a melting point of approximately 183°C, good electrical conductivity, and are relatively easy to use.
- The key differences between 60/40 and 63/37 solder lie in their eutectic properties, fluidity during soldering, strength and reliability of joints, and environmental considerations.
- 60/40 solder is non-eutectic, requires careful handling, and contains more lead, while 63/37 solder is eutectic, provides better fluidity during soldering, forms stronger joints, and contains slightly less lead.
