[0002] Circuit board processing fixtures are tools used to fix and support circuit boards during the processing process. They can be used in different links such as welding, assembly, and testing. These fixtures can improve processing accuracy and efficiency and ensure the quality of the final product.

[0003] Chinese patent CN219718616U discloses a fixture for processing circuit boards, comprising: a base plate, a flat plate, longitudinal and transverse grooves, a threaded channel, and a fixture block. The top surface of the flat plate is provided with longitudinal and transverse grooves. The flat plate is detachably connected to the base plate via fixing bolts. The flat plates can be combined with each other. The bottom surface of the longitudinal and transverse grooves is provided with a threaded channel. The fixture block can be threadedly connected to the inner diameter surface of the threaded channel and can move along the threaded channel. Grooves are provided on the flat plate, crisscrossing each other. The bottom of the grooves is provided with a threaded channel. The fixture block can be threaded into the threaded channel and pushed vertically and horizontally along the threaded channel, thereby reducing the spacing between the fixture blocks and clamping the four edges of the circuit board, thereby stabilizing the circuit board clamping. By fixing the flat plates together, the area of ​​the fixture flat plates can be changed to accommodate the clamping and fixation of circuit boards of various specifications.
