Description

Technical Field

[0001] The utility model relates to the technical field of selective wave soldering, in particular to a tin surge clamping channel of selective wave soldering equipment. Background Art

[0002] Selective wave soldering is a special wave soldering method. It uses a tiny nozzle to form a columnar wave or a small rectangular wave with a diameter of several millimeters to achieve point-by-point soldering for a single point or a local area. The main soldering methods of selective wave soldering include drag soldering and dip soldering. Generally, drag soldering is preferred because the nozzle that sprays molten solder during drag soldering can preheat the adjacent pins to a certain extent, and the nozzle moves horizontally at a uniform speed, which can avoid the occurrence of solder joint tip defects and ensure the quality of solder joints. Its speed is usually set to 2-5mm / s, which is more efficient than dip soldering. When wave soldering electronic components on PCB boards, the height of the tin surge needs to be adjusted, so that the soldering quality of the PCB board can be improved when the PCB board is soldered. Therefore, a tin surge clamping groove of a selective wave soldering device is proposed. Utility Model Content

[0005] As a further improvement of the technical solution, a feed port is fixedly installed on the side of the threaded connection shell, the feed port is connected to the interior of the threaded connection shell, and the feed port is arranged at an angle.

[0006] As a further improvement of the technical solution, a nozzle is threadedly connected to the threaded shell, and the nozzle is arranged in a cone shape near the top side, and the side surface of the nozzle plugging metal block is adapted to the cone inside the nozzle near the top side.
