Description

Technical Field

[0001] The utility model relates to the technical field of PCB hanging baskets, in particular to a PCB immersion gold fixing basket. Background Art

[0002] When the PCB passes through the gold-plating wire, it is required to have good contact with the liquid medicine to achieve a good gold effect on the surface. For this reason, the common practice in the industry is to insert the PCB to be gold-plated into the spacing net of the hanging basket. According to the production process, the hanging basket is lifted by the machine and placed in each liquid medicine tank in turn. The liquid medicine in the liquid medicine tank can penetrate into the spacing net, so that the surface of the PCB board and the liquid medicine can fully react.

[0003] In the related art, the spacing net formed by the hanging basket does not have an ideal limiting effect on the PCB board, which causes the PCB board to shake and overlap easily, especially for thin boards (thickness less than 0.7mm). Utility Model Content
