Description

Technical Field

[0001] The utility model relates to the technical field of copper deposition, in particular to a plate mount for improving copper deposition efficiency. Background Art

[0002] The quality of the copper plating process is directly related to the quality of the produced circuit boards. Copper plating is an autocatalytic reaction of chemical copper plating induced by the activation of palladium nuclei. The newly generated chemical copper and the reaction by-product hydrogen can act as catalysts to catalyze the reaction, so that the copper plating reaction continues. After this step, a layer of chemical copper can be deposited on the board surface or hole wall. The board rack is a commonly used tool in the preparation of circuit boards.

[0003] Currently, Chinese patent CN220457667U discloses a PCB copper sinking hanging basket. The copper sinking hanging basket comprises a board inserting frame and a target crossbar fixing bracket. Bottom crossbar brackets are provided on the front and rear sides of the bottom of the board inserting frame. The bottom crossbar brackets are inclined linearly from both ends to the middle, thereby forming PCB placement areas on the board inserting frame and on both sides of the middle of the bottom crossbar. However, in actual use, the existing upper board rack has a single-tooth locking plate rib, which means that only two rows of boards can be inserted into one rack for production. This design reduces production output, has low flexibility, and is difficult to adjust according to production needs. In addition, when the production load is insufficient, the solution reaction is inactive, which leads to problems such as poor backlighting during copper sinking. Utility Model Content

Compared with the traditional screw locking plate ribs, the serrated slot locking plate ribs can make the bottom extension strip less prone to damage, have a long service life, and are simple to operate.

[0011] Preferably, the tooth pitch between two adjacent serrations on the upper surface of the bottom insertion row is 2CM.

[0012] Preferably, the distance between two adjacent racks on the upper surface of the bottom insertion row is 5CM.

[0013] Preferably, the structure of the active socket strip is the same as that of the bottom socket strip, and two active socket strips are provided. By increasing the number of socket strips, the production load can be effectively increased, thereby improving the activity of the solution reaction and avoiding the problem of poor backlight of the copper plating.

[0014] Preferably, the auxiliary positioning assembly includes a U-shaped guide rail and a positioning slider. The U-shaped guide rail is fixed to the outside of the connecting frame. The U-shaped guide rail is symmetrically arranged about the center line of the connecting frame. The U-shaped guide rail is slidably connected to the positioning slider.

The positioning slider slides up and down on the U-shaped guide rail, and the position of the movable strip can be flexibly adjusted according to actual conditions.

[0015] Preferably, the auxiliary positioning component also includes a positioning screw and a positioning hole. The inner side of the positioning slider is connected to the positioning screw, which is threadedly connected to the positioning hole. The positioning hole is opened on the inner side of the U-shaped guide rail. The positioning screw passes through the positioning slider and is locked in the positioning hole. The movable socket can be fixed on the U-shaped guide rail, and vice versa, it can be adjusted movably.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This upper plate rack, which improves copper deposition efficiency, is equipped with a bottom plug-in strip and two movable plug-in strips, so that one rack can insert three rows, effectively increasing the load, thereby improving production and potion activity. It also greatly improves service life and simplifies operation by replacing the original screw-locking plate strips on the plug-in strips with sawtooth-shaped slot-locking plate strips. The device also allows height adjustment through auxiliary positioning components. The device has a multi-layer adjustable design, effectively improving copper deposition efficiency, thereby achieving a more efficient, stable and controllable copper deposition process, thereby improving production efficiency and product quality.

[0018] The upper plate rack for improving copper deposition efficiency is provided with symmetrical U-shaped guide rails on both sides of the upper plate rack body, which can enable the movable plug-in strip to move in a directional manner with high flexibility. By providing a number of equally spaced positioning holes on the U-shaped guide rails, it is convenient to adjust the height according to actual conditions to adapt to different process conditions and copper deposition requirements, thereby optimizing the copper deposition effect.
