Solders are made with a variety of alloys with varying melting temperatures, which typically range from 47 degrees Celsius to 1064 degrees Celsius. Low temperature soldering material is preferred for certain applications that require decreased operational costs. Likewise, it may help reduce materials, labor requirements, and energy, too. Low temperature solder material can eliminate the need to have two SMT steps. Likewise, it can be a wave soldering step to add value while ensuring lower total cost of ownership. Here are ways to choose the best low temperature soldering material:
• Take note of the main key considerations – Factors like the temperature range of your components, the required thermal properties, and the device’s final operating temperature are crucial when choosing a low temperature soldering material. You also need to consider CTE mismatch and unique properties like lead-free.
• Explore different types of soldering material – Reputable manufacturers typically offer soldering material in different varieties for various applications like low temperature processing and fine feature printing. Make sure that the product has low drossing rates and low oxides, excellent solderability, high purity, and good wetting. Some soldering materials are lead-free, while others contain tin-lead.
• Consider the joining application – Low temperature solders may be used in many different joining applications. In cryogenics, for instance, pure indium metal alloy is used in the low temperature soldering material because it can maintain its malleability, even when liquefied gasses experience extreme temperatures. The metal is known for its excellent thermal conductivity and the malleability and softness lets it compensate for a CTE mismatch between various joined surfaces, including any rough surface.
• A low melting alloy is recommended for thermometers used in food preparation, and in devices used in fire detection. Some electrical fuses may rely on low temperature soldering material to increase their safety.
