Abstract
Description

[0002] Wave soldering is a process that allows the soldering surface of the plug-in board to directly contact with high-temperature liquid tin to achieve the purpose of soldering. During the operation, the high-temperature liquid tin maintains an inclined surface, and a special device is used to make the liquid tin form a wave-like phenomenon, so it is called "wave soldering".
[0003] In the process of implementing the solution, the inventors found that the following problems in the prior art have not been well solved: the traditional wave soldering fixture also contains a spring pressure sheet, which is the same as the presser foot and is also limited on the frame of the fixture by screws. The spring pressure sheet is a continuous arc shape, and its end away from the screw has downward pressure. The metal sheet can adjust the downward pressure position of its end by rotating its position, so as to achieve downward pressure limiting at different places. The difference between it and the presser foot is that the downward pressure end can reach a farther distance, but due to the limited length of the metal sheet, the reachable length is limited, so that the downward pressure limiting distance is also relatively limited, and the scope of application is small.
