Description

Technical Field

[0001] This utility model relates to the field of printed circuit board manufacturing technology, specifically a thin-film microelectrode based on printed circuit board manufacturing process. Background Technology

[0002] With the increasing demand for high-performance, miniaturized sensors in fields such as biomedical detection, environmental monitoring, and safety monitoring, thin-film microelectrodes based on printed circuit board manufacturing processes have become an important direction for sensor miniaturization due to their advantages of high precision and mass production capability. In the fabrication process of these microelectrodes, the electroplating process is the key step that determines their performance, and the design rationality of the electroplating tank, as the core equipment of the electroplating process, directly affects the production quality, efficiency, and energy consumption of the microelectrodes.

[0003] Traditional electroplating tanks are typically large, single-space structures, with their design capacity determined by the needs of the largest production batch. However, in actual production, due to the diversity and volatility of order demands, the scale of production batches varies greatly, often resulting in small-batch production. When small-batch production is carried out, most of the space in a traditional large electroplating tank is idle. However, in order to ensure the normal operation of the electroplating process, the plating solution in the entire electroplating tank still needs to be heated, stirred, and circulated. This leads to a large amount of energy waste and increases the energy consumption cost of production. Therefore, we propose a thin-film microelectrode based on printed circuit board manufacturing process. Utility Model Content

According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-5 As shown, this utility model provides a technical solution: a thin-film microelectrode based on printed circuit board manufacturing process, including an electroplating tank 1, with multiple sets of snap-fit ​​grooves 3 inside the electroplating tank 1, and a partition plate 4 slidably connected inside each snap-fit ​​groove 3. Both sides of the partition plate 4 are provided with sealing structures. The electroplating tank 1 is connected to a fume hood 2 through a lifting structure. Multiple mounting plates 9 are fixedly installed on the inner side wall of the fume hood 2, and multiple clamping structures are provided on the side of each mounting plate 9.

[0018] In an optional embodiment: the sealing structure includes a plurality of sealing plates 5, which are fixedly installed on the side of the partition plate 4. A sealing airbag 6 is provided in the middle of the plurality of sealing plates 5. The sealing airbag 6 is fixedly installed on the side of the partition plate 4. An air inlet pipe 7 is fixedly installed on the side of the sealing airbag 6. A sealing plug is provided at one end of the air inlet pipe 7. A sealing gasket 8 is fixedly installed at the bottom of the partition plate 4.

[0019] It should be noted that the sealing plate 5 can provide the first layer of sealing. When the sealing airbag 6 inflates, it contacts the inner wall of the snap-fit ​​groove 3 and fills the uneven areas inside the snap-fit ​​groove 3 with the flexibility of the sealing airbag 6, thus achieving the effect of a second layer of sealing.

[0020] In an optional embodiment: both the sealing airbag 6 and the sealing gasket 8 are made of chemically resistant fluororubber, the inner layer of the sealing airbag 6 is provided with a tear-resistant reinforcing layer, and the outer surface of the sealing airbag 6 is smoothed.

[0021] It should be noted that, especially in strong acid and high temperature environments, fluororubber can withstand most chemical media. The reinforcing layer, such as polytetrafluoroethylene fiber, improves tear resistance, and the surface is smoothed to reduce electroplating solution residue and crystal adhesion.

[0022] In an optional embodiment: the lifting structure includes two lifting cylinders 17, which are located at the side ends of the electroplating tank 1 respectively. Fixing plates 16 are fixedly installed at both ends of the two lifting cylinders 17 respectively, and the two fixing plates 16 are fixedly installed on the outer side walls of the electroplating tank 1 and the fume hood 2 respectively.

[0023] It should be noted that by activating the lifting cylinder 17, the telescopic end of the lifting cylinder 17 moves up or down, which can move the fume hood 2 up and down, thereby moving the clamped circuit board up or down, and thus completing the electroplating of the circuit board.

[0024] In an optional embodiment: each clamping structure includes a clamping plate 11, which is fixedly installed on the side of the mounting plate 9. A clamping plate 2 12 is provided on one side of the clamping plate 11. Two T-shaped rods 13 are slidably connected to the side of the clamping plate 2 12. The two T-shaped rods 13 pass through the side wall of the clamping plate 2 12 and are fixedly installed on the side of the mounting plate 9. A compression spring 14 is sleeved on the outer surface of the T-shaped rod 13. The two ends of the compression spring 14 are respectively fixedly installed on the opposite side of the T-shaped rod 13 and the clamping plate 2 12.

[0025] It should be noted that after the clamping plate 12 is pulled outward, the compression spring 14 is compressed, and a distance will be generated between the clamping plate 11 and the clamping plate 12. The printed circuit board is placed between the two, and then the clamping plate 12 is pressed against the side wall of the circuit board by the elastic action of the compression spring 14, thereby clamping the circuit board.

[0026] In an optional embodiment: a handle 15 is fixedly installed on the side end of the clamping plate 2 12. The handle 15 is located in the middle of the two T-shaped bars 13 and is cylindrical.

[0027] It should be noted that the clamping plate 12 can be pulled outward by the lever 15, so that the distance between the clamping plate 11 and the clamping plate 12 is separated, which makes it easier to place the printed circuit board between the two, thereby completing the clamping.

[0028] In an optional embodiment: the side end of the fume hood 2 is provided with a plurality of through slots 10, and the longitudinal section of the plurality of through slots 10 is U-shaped.

[0029] It should be noted that when the smoke hood 2 is pressed down, it will not compress the air intake pipe 7.

[0030] In an optional embodiment: an exhaust pipe 18 is fixedly installed on the upper end of the flue hood 2, and one end of the exhaust pipe 18 is connected to the spray tower.

[0031] It should be noted that a negative pressure fan is installed at one end of the exhaust pipe 18 or inside the spray tower to draw acid mist and harmful gases generated by electroplating to the spray tower for treatment, ensuring that the exhaust gas meets emission standards.

[0032] In practical use, the working principle of this utility model is as follows: Multiple sets of positive and negative electrode posts are installed in the electroplating tank 1, located between different partition plates 4. Depending on the production needs of different batches, when there is a large demand, all partition plates 4 can be removed. When there is a small demand, the partition plates 4 can be inserted into the snap-fit ​​groove 3 to divide the electroplating tank 1 into multiple independent spaces. Electroplating can be performed in one of these spaces, or electroplating can be performed separately according to different process requirements. When the partition plate 4 is inserted into the snap-fit ​​groove 3, the sealing plate 5 can provide the first layer of sealing. Then, gas is delivered into the sealing airbag 6 through the air inlet pipe 7. When the sealing airbag 6 inflates, it contacts the inner wall of the snap-fit ​​groove 3 and fills the uneven areas inside the snap-fit ​​groove 3 with the flexibility of the sealing airbag 6, achieving a second layer of sealing. During electroplating, the printed circuit board is clamped and fixed by the clamping structure. Then, the fume hood 2 is lowered by the lifting structure to allow the printed circuit board to enter the electroplating tank 1. After electroplating is completed, it is lifted again.

[0033] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
