One of the drawbacks of the 60/40 solder is that it is not eutectic. The temperature of the environment should be between 10 to 40 degrees Celsius. It is crucial to store this solder in a non-corrosive and dry environment. The 60/40 solder is ideal for use in electronics and PCB manufacturing. Furthermore, this solder composition creates a strong and permanent bond in metals. This solder flows well and it is very easy to use.Ħ0/40 solder features good properties such as exceptional thermal conductivity and electrical conductivity. Also, 60/40 solder melting point is 190 degree Celsius. However, it is still referred to as non-eutectic solder. The melting point of 60/40 solder is very close to eutectic temperature. This solder is one of the alloy in the soft solder family. It is also referred to as alloy Sn60Pb40. The mixture of nickel in alloy or the use of conformal coatings can help in preventing tin whiskers from forming.Ħ0/40 solder is a metal alloy that comprises 60% tin and 40% lead. Also, copper enhances mechanical strength and conductivity. The integration of Silver helps in reducing oxidization. For instance, tin-silver-copper alloy features a very low melting point of 217 degrees Celsius. Manufactures had to develop solders that feature unique properties to prevent these problems. Furthermore lead-free solders don’t flow well and they tend to form less strong joints. Therefore, lead free solders have more stress on components during PCB assembly. However, the melting points of lead-free solders are higher than leaded ones. Other metals used include nickel and silver. Lead free solders offer more strength to alloy. Tin serves as the base material of this solder. Lead free solders comprise different metals. The EU restricted the use of hazardous substance by issuing the Restriction of Hazardous Substances directive in response to the concerns about the use of lead. It can contaminate ground and soil water. Lead is a dangerous substance as it is poisonous to humans and their environment. Lead alloy solders feature properties which make people refer to them as soft solders.įurthermore, the use of lead in this alloy has the formation of tin whiskers. Also, it is easy to work with leaded solder. Therefore, this makes then bond materials well. Also, leaded solder feature very low melting point which is usually about 180 degree Celsius. 60% tin and 40% lead or 63% tin and 37% lead are the most common composition. These types of solders comprise lead and other metals. These are lead alloy solders and lead free solders. There are two major types of solders based on the use of lead. Some solders are specially designed for specific applications or industries. Typically, solder features a low melting point which is always around 200 degrees Celsius.Īlso, solders are available in different form factors. Therefore, this made lead-free solder more commonly used in recent times. For many years, tin and alloy have been used to make solder.Īs time went on, there were concerns about the environmental and health hazards of lead. Therefore, solder used in this field must have great conductive properties. In electronics production, engineers make use of solder to fix components to circuit boards. For solder to create a strong bond, its melting point should be below the pieces it is joining.Īfter the melting phase, the solder cools down and the parts bond permanently. Solder is generated by melting the solder. Traditionally, solder comprises tin and lead with more percentage of tin. It is a metal alloy that combines different materials like tin and lead. Solder is a material used in creating a strong bond between metal parts. What is the difference between these two types of solder and what benefits do they offer? What is Solder made of? In this article, we will be comparing the most common solder compositions which are 60/40 Vs 63/37 solder. In most cases, tin accounts for more percentage than lead. These parameters include reflow characteristics, melting point, and creep behavior among others. There are several parameters that determine the composition of solder. Also, these two materials are usually melted using hot iron. The combination of thin and lead is what produces solder. Solder is a metal alloy that comprises lead and tin.
