[0002] Reflow soldering equipment is equipped with a heating circuit inside, which heats the air or nitrogen to a sufficiently high temperature and blows it toward the circuit board with components already attached, so that the solder on both sides of the components melts and then bonds to the main board. It has the characteristics of easy temperature control and good soldering effect.
[0003] In order to ensure the temperature in actual use, it is usually necessary to use a furnace temperature tester to enter the interior for temperature testing. In the future, in order to avoid damage to the furnace temperature tester, it is usually necessary to use a carrier to load it and drive the furnace temperature tester to move. The guide rails for sliding the carrier inside different reflow soldering equipment have different spacing settings. Usually, a dedicated temperature measuring carrier is required, which is costly. When a retractable temperature measuring carrier is used, it is difficult to adjust the spacing on both sides, resulting in the thermometer being not centered when entering the equipment for temperature measurement, resulting in differences in test data. For this reason, a temperature measuring carrier for reflow soldering is provided to solve the above problems. Utility Model Content
