Description

Technical Field

[0001] This utility model belongs to the technical field of HDI board blind hole electroplating device, and particularly relates to an HDI board blind hole electroplating device. Background Technology

[0002] High-density interconnect (HDI) manufacturing is one of the fastest-growing areas in the printed circuit board (PCB) industry. HDI boards are a type of PCB with high wiring density, achieved through micro-blind via technology. HDI boards are divided into inner and outer layers, with internal connections between these layers achieved through drilling and metallization. Therefore, the higher the application of HDI technology, the higher the manufacturing level of the laminate. Ordinary HDI boards undergo a single lamination process, while high-end HDI boards employ two, three, or even more lamination processes, as well as electroplating for hole filling, hole stacking, and laser direct drilling.

[0003] Chinese patent CN214960366U discloses an HDI circuit board blind via electroplating device, including a fixed platform with slide rails fixed on both sides. A fixed frame is located above the fixed platform and connected to the slide rails via support rods. A lifting plate is connected to the bottom of the fixed frame via a pneumatic telescopic rod. A movable plate is slidably mounted on the bottom of the lifting plate, and clamps are evenly fixed on the bottom of the movable plate. An electroplating tank is fixed on the left side of the fixed platform, and a circulation pump is fixed below the electroplating tank. The slide rails facilitate the transport and electroplating of the HDI circuit board, making it more convenient to use. During electroplating, the drive motor is started, causing the movable plate to move continuously in small amplitudes. At the same time, the circulation pump allows the electroplating solution in the electroplating tank to flow slowly from left to right. This, combined with the shaking of the circuit board, allows the electroplating solution to fully enter the blind vias on the workpiece, thus improving contact with the electroplating solution and significantly improving electroplating quality and efficiency.

[0004] However, the above patent has the following shortcomings: after the circuit board is electroplated, the excess electroplating solution on it is discharged freely, which wastes time and leads to low efficiency. Therefore, it needs to be improved. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-3 The present invention provides a technical solution: an HDI board blind hole electroplating device, including a machine base 1, a frame 2 vertically installed on the top of the machine base 1, and a horizontal movement component provided on the frame 2, a circular body 7 provided on the top of the machine base 1, and a rotating component provided on the circular body 7, and a support component provided on the outside of the circular body 7, and an electroplating tank 15 and a spin-drying tank 16 installed on the top of the machine base 1.

[0028] The rotating assembly includes a second motor 14, a rotating disk 11, a rotating column 8, and a mounting bracket 9. The second motor 14 is vertically mounted on the bottom of the circular body 7, and the rotating disk 11 is mounted on the output end of the second motor 14. The rotating column 8 is vertically mounted on the bottom of the rotating disk 11, and multiple mounting brackets 9 are horizontally mounted on the outer side of the rotating column 8. Multiple clamps 10 are mounted on each mounting bracket 9.

[0029] Specifically, when it is necessary to spin-dry the material held on the clamp 10, the rotating column 8 is moved and inserted into the spin-drying tank 16, and then the second motor 14 is started to drive the rotating disk 11 to rotate. The rotating disk 11 drives the rotating column 8 to rotate, and the rotating column 8 drives the mounting frame 9 and the clamp 10 to move, thereby spinning off the electroplating liquid on the material. The speed of the second motor 14 is relatively slow in the electroplating tank 15, and the speed of the second motor 14 is relatively fast in the spin-drying tank 16, which improves production efficiency.

[0030] Furthermore, the support assembly includes an L-shaped body 12, and multiple L-shaped bodies 12 are vertically mounted on the outer side of the rotating disk 11, with the bent portion of the L-shaped body 12 slidably connected to the top of the circular body 7.

[0031] Specifically, during the rotation of the rotating disk 11, the L-shaped body 12 installed on the outer side of the rotating disk 11 is bent and slides on the top of the circular body 7, thereby improving the stability of the rotation of the rotating disk 11.

[0032] Furthermore, casters 13 are installed at the bending parts of the circular body 7, and the casters 13 are located at the top of the circular body 7 and rotate.

[0033] Specifically, the universal wheel 13 is installed by bending the L-shaped body 12, which can reduce the friction between the L-shaped body 12 and the circular body 7.

[0034] Furthermore, the lateral motion assembly includes a lead screw 3, a threaded block 4, and a first motor 5. The lead screw 3 is laterally rotatably mounted inside the frame 2, and the threaded block 4 is threadedly engaged on the outside of the lead screw 3. The first motor 5 is mounted on the outside of the frame 2, and the first motor 5 is used to drive the lead screw 3 to rotate.

[0035] Specifically, when it is necessary to move the material on the fixture 10 laterally, the first motor 5 is started to drive the lead screw 3 to rotate. During the rotation of the lead screw 3, the threaded block 4 is moved laterally, thereby driving the material on the rotating column 8 to be inserted into the electroplating tank 15 and the spin dryer 16 for processing.

[0036] Furthermore, an electric push rod 6 is vertically mounted at the bottom of the threaded block 4, and a circular body 7 is mounted at the output end of the electric push rod 6;

[0037] Specifically, when it is necessary to insert the rotating column 8 into the electroplating tank 15 or the spin-drying tank 16, the electric push rod 6 is activated to drive the circular body 7, the rotating disk 11 and the rotating column 8 into the electroplating tank 15 or the spin-drying tank 16, thereby adjusting the vertical position of the material.

[0038] The working principle and usage process of this utility model are as follows: When it is necessary to move the material on the clamp 10 laterally, the first motor 5 is started to drive the lead screw 3 to rotate. During the rotation of the lead screw 3, the threaded block 4 is moved laterally. Then, the electric push rod 6 is started to drive the circular body 7, the rotating disk 11 and the rotating column 8 to be inserted into the electroplating tank 15 or the spin-drying tank 16. The second motor 14 is started to drive the rotating disk 11 to rotate. The rotating disk 11 drives the rotating column 8 to rotate. The rotating column 8 drives the mounting frame 9 and the clamp 10 to move, thereby spin-drying the electroplating liquid on the material.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
