What is 63/37 Solder?

63/37 solder, often referred to as eutectic solder, is another commonly used solder alloy. It contains 63% tin and 37% lead. Unlike 60/40 solder, 63/37 solder is eutectic, which means it has a single, sharp melting point. This property makes it particularly suitable for applications where precise control over the soldering process is crucial.

63/37 solder, composed of 63% tin and 37% lead, boasts a low melting point at 183 degrees Celsius, distinguishing it from 60/40 solder. Its standout feature is its eutectic nature, bypassing a semi-solid state, making it remarkably user-friendly and less prone to flawed joints. Ideal for hand soldering tasks, it finds common usage in plating and wave soldering. In plating, it serves as a corrosion-resistant coating, doubling as a soldering base. It's available in various forms, including foils, solder paste, and bars, and many people know it as 63Sn/37Pb solder, appreciating its ease of use and dependable properties.

Difference between 60/40 vs 63/37 Solder

Now, let's explore the key differences between 60/40 and 63/37 solder:

- Melting Point: One of the most significant differences is the melting point. 60/40 solder has a lower melting point, typically around 183°C (361°F). In contrast, 63/37 solder, being eutectic, has a sharp melting point at 183°C (361°F). This means that 63/37 solder transitions directly from a solid to a liquid state, making it ideal for applications where precise temperature control is necessary.

- Fluidity: Due to its eutectic nature, 63/37 solder also exhibits better fluidity during the soldering process. It flows more evenly and smoothly, reducing the likelihood of solder bridges or cold joints.

- Strength and Reliability: While both solders create strong and reliable solder joints, 60/40 solder may be slightly less robust due to its non-eutectic nature. However, this difference is often negligible for most electronics applications.

Features:

1. Have been treated by special technology with oxide removal and antioxidant bearing.
2. Easy to use, flows well, and heats evenly.
3. Good solderability both in electrical conductivity and thermal conductivity.
4. High activity flux makes more reliable soldering and leaves bright shiny solder joints after reflow.
5. With the solder wire reel, soldering can be accomplished quickly.
6. Widely applied in electrical repairs
