Solder patse 63/37 in Syringe

Solder paste is an essential component of electronic assembly processes, and it is commonly used to join surface-mounted components to printed circuit boards (PCBs). The use of solder paste in syringes has become increasingly popular in recent years, as it allows for precise application and minimizes waste. One of the most commonly used types of solder paste in syringes is 63/37 solder paste (also known as solder passte Sn63Pb37 in Syringe). In this article, we will discuss what 63/37 solder paste is, its advantages, and how to use it effectively.

 

What is 63/37 Solder Paste in syringe? 

63/37 solder paste is a type of solder paste that is made up of 63% tin and 37% lead. It is also known as eutectic solder, which means that it has a specific melting point that allows it to solidify quickly without undergoing any phase changes. This property makes 63/37 solder paste ideal for use in electronic assembly processes, where precise and consistent soldering is required.

 

63/37 solder paste is typically supplied in syringes, which are filled with a mixture of solder powder, flux, and a carrier material. The carrier material is usually a mixture of organic solvents and binders, which help to keep the solder powder and flux in a uniform consistency. The flux in the solder paste serves several functions, including removing oxide layers from the metal surfaces to be soldered, preventing the formation of new oxides, and promoting wetting and bonding between the solder and the metal surfaces.

Advantages of 63/37 Solder Paste: 

One of the main advantages of using 63/37 solder paste is its eutectic composition, which ensures a consistent melting and solidification point. This property makes it easier to control the soldering process, ensuring a uniform bond between the components and the PCB. This is especially important in high-precision electronic assemblies, where even small variations in the soldering process can lead to significant defects.

 

Another advantage of 63/37 solder paste is its relatively low melting point, which makes it easy to work with using standard soldering equipment. The melting point of 63/37 solder paste is around 183°C (361°F), which is lower than many other types of solder paste. This makes it easier to avoid overheating the components and PCB during the soldering process, reducing the risk of damage to the electronics.

 

Additionally, the use of solder paste in syringes allows for precise and controlled application of the paste. The syringe can be fitted with a fine tip, allowing for the solder paste to be applied exactly where it is needed. This minimizes the amount of waste and ensures a high degree of accuracy in the soldering process.
