[0002] Reflow soldering technology is not unfamiliar in the field of electronic manufacturing. The components on various boards used in our computers are all soldered to the circuit boards through this process. There is a heating circuit inside this device, which heats air or nitrogen to a high enough temperature and then blows it onto the circuit board with components already attached, so that the solder on both sides of the components melts and bonds with the main board. The advantages of this process are that the temperature is easy to control, oxidation can be avoided during the soldering process, and the manufacturing cost is easier to control.

[0003] When processing existing circuit boards, they need to be transported. Currently, most of the existing transportation devices are circuit board turnover carts. Most of the circuit board turnover carts on the market store circuit boards through the grooves between movable plates. However, when dealing with different models of circuit boards, the distance between the movable plates needs to be adjusted, and after adjustment, the movable plates need to be locked. Currently, the locking devices of circuit board turnover carts need to be located on both sides of the top of the movable plates, and the opening process is cumbersome and requires two or more people to operate simultaneously, which is rather troublesome to use.

[0004] Therefore, how to provide a sheet material carrier for a reflow soldering furnace used in the processing of controller circuit boards to solve the problems existing in the prior art is of great significance for its application. Summary of the Utility Model
