[0002] PCB sheets are lightweight, flexible, bendable, foldable, and can realize multi-layer wiring. They are widely used in various electronic devices, such as mobile phones, tablet computers, wearable devices, etc. When electroplating PCB sheets, in order to ensure the stability and accuracy of the PCB sheets during the electroplating process, it is necessary to open holes for clamping on the side. These holes can provide a stable support point so that the PCB sheets will not slide or deform during the electroplating process.

[0003] The utility model with announcement number CN209144296U discloses a fixture for PCB thin plate electroplating production, including a fixed hanger, a movable hanger and an electroplating Feiba conductive beam.

[0004] In the process of implementing this application, it was found that the technology has the following problems: in the above patent document, when the PCB sheet is electroplated and clamped, one side of the PCB sheet to be produced is clamped into the slot of the fixing hanger, and a plurality of first screws are used to pass through and lock it, so as to clamp the side of the PCB sheet; the installation place of the first screw in the document is composed of a plurality of through holes, so that the first screw can pass through, and the passed first screw will also pass through the hole for clamping on the PCB sheet, and when facing PCB sheets of different sizes, the number of holes opened on the side is different, and the distance between two adjacent holes is also different; however, the hole spacing at the place where the first screw passes through in the document is the same, which cannot adapt to the electroplating clamping of PCB sheets of different sizes, and the flexibility is poor.

[0005] For this reason, a fixture for PCB thin plate electroplating production is proposed. Utility Model Content
