How to determine the furnace temperature curve of medium-temperature lead-free solder paste?

insmtIn the process, the setting of the furnace temperature curve for lead-free solder paste is a very important step, as it directly affects the soldering quality of lead-free solder paste. Therefore, masterMedium-temperature lead-free solder pasteThe furnace temperature parameters are very important. We should determine the appropriate furnace temperature curve of lead-free solder paste based on its process characteristics. How exactly should this be done? Now, JJY solder Paste Manufacturer will explain it to you:

Under normal circumstances, the oven temperature for medium-temperature lead-free solder paste is180-230Between degrees Celsius, but the specific temperature setting should be based on the composition and viscosity of the material.PCBIt is determined by factors such as the design of the plate and the welding process. Generally speaking, the higher the furnace temperature, the better the welding quality. However, if the furnace temperature is too high, it can also cause cracks and gaps at the welding points, which will reduce the welding quality. Therefore, in practical applications, we need to adjust the parameters according to specific circumstances to achieve the best welding effect.

In addition to the furnace temperature, the baking time is also one of the factors affecting the quality of solder joints. Generally speaking, the baking time for medium-temperature lead-free solder paste is60-120Within seconds, if the time is too short, the strength of the welding point will be insufficient; if it is too long, the welding point will become brittle, making it difficult to meet the actual requirements. Therefore, when soldering medium-temperature lead-free solder paste, we need to set the parameters reasonably according to the actual situation to achieve the best soldering effect.

Overall, the furnace temperature parameters of medium-temperature lead-free solder paste are a very important factor. They directly affect the soldering process and the quality and thermal stability of lead-free solder paste.

In conclusion, the furnace temperature parameters and baking time of medium-temperature lead-free solder paste are interrelated, and multiple factors need to be comprehensively considered to achieve the best soldering effect. In practical application, we need to adjust the parameters according to different situations and closely monitor the welding quality to improve production efficiency and product quality.
