How to set the reflow temperature? When setting the reflow temperature, we often refer to the type of solder paste we choose. The melting point of each different solder paste is also different, and its optimal process requirements are also very different.

In order to ensure the orderly production and the qualified rate of products, how to set the furnace temperature has become a technical and empirical problem. Generally, our solder paste suppliers will provide us with a process description of solder paste, detailing the requirements of solder paste in preheating, constant temperature, reflux, cooling and maximum temperature. In China, most reflow soldering has an error of 5-20 degrees Celsius, so at this time, it is necessary to use a furnace temperature tester to carry out the most accurate detection of our furnace, and compare the measured data with the process requirements and temperature curves provided by solder paste suppliers to make the process close to the standard.

Pay special attention to this point. At present, there are many furnace temperature testers in China. It is recommended to use Weicon and KIC furnace temperature testers.
