Detailed Description

The technical solution of the present invention is further described and illustrated by the following specific embodiments.

As shown in fig. 1 and 2, an electroplating fixture includes a first steel plate 10, and a plurality of clamping devices are disposed on two sides of the first steel plate 10 for clamping an electroplating plate. Each clamping device comprises a first clamping plate 1, a second clamping plate 2 and a third clamping plate 3, wherein the third clamping plate 3 is positioned between the first clamping plate 1 and the second clamping plate 2, a first opening 4 is formed between the first clamping plate 1 and the third clamping plate 3, and a second opening 5 is formed between the second clamping plate 2 and the third clamping plate 3. The first clamping plate 1 is provided with a first threaded hole 6, and a first clamping screw 7 is installed in the first threaded hole 6. The second splint 2 is provided with a second threaded hole 8, and a second clamping screw 9 is installed in the second threaded hole 8.

The width of the first steel plate 10 is 35-36 mm, the width of the first opening 4 and the second opening 5 is 2mm, and the thickness of the third clamping plate 3 is 10 mm. The number of clamping devices is set according to the actual situation. The two sides of the electroplating clamp are provided with the clamping devices, so that the utilization efficiency of the electroplating clamp can be improved, and the floor area of the electroplating clamp is reduced. The first opening 4 and the second opening 5 are arranged in the single-side clamping device simultaneously, the number of the electroplating clamps for clamping the PCB is increased, the occupied area of the electroplating clamps is reduced, the production efficiency is improved, and the application range is enlarged.

As shown in fig. 3, in the embodiment, two PCB boards can be placed into the first opening 4 and the second opening 5 at the same time for electroplating, so that the number of the PCB boards clamped by the electroplating fixture is increased, and the production efficiency is improved. As shown in fig. 4, by adjusting the length of the clamping screw screwed into the opening, a circuit board can be placed into the first opening 4 and the second opening 5 for electroplating, which is particularly suitable for electroplating CEM-1 white boards, two CEM-1 white boards are placed into the first opening 4 and the second opening 5, and the third clamping plate 3 is spaced between the first opening 4 and the second opening 5, so that the electroplating solution can be soaked uniformly, even if the electroplating solution is acidic, and under the influence of temperature and electroplating time, the phenomenon that the surface of the CEM-1 white board is partially yellow after being electroplated can be avoided, and the production efficiency and the production quality of the CEM-1 white board electroplating can be improved.
