Description

Technical Field

[0001] This application relates to the field of electroplating line technology, and more specifically, to a pretreatment system for improving bubble-type pore breakage in STS electroplating lines. Background Technology

[0002] In STS (Selector Switch) plating lines, insufficient pretreatment cleaning, poor hydrophilicity in the holes, or residual air bubbles prevent the copper plating solution from penetrating the holes after the board enters the copper bath, resulting in hole breakage. This leads to a low defect rate of bubble-type hole breakage in STS plating lines, with a batch defect rate of approximately 1.3% and a pc defect rate of approximately 0.01-0.90%. This has caused a large number of scraps and increased the cost of electrical testing and retesting. It is also easy for this to be missed downstream, leading to customer complaints. There is an urgent need to thoroughly improve this type of hole breakage.

[0003] The current pretreatment process for the STS electroplating line is as follows: degreasing tank → hot water rinse → water rinse *3 → pickling → water rinse *2 → pre-copper acid → copper tank. All chemical tanks and water rinse tanks are immersion type, resulting in insufficient cleaning ability of the pretreatment process for the electroplating line, causing bubble-type pores to break in the electroplating line.

[0004] Therefore, this application aims to provide an improved pretreatment system for bubble-type pore breakage in STS electroplating lines to better solve the above-mentioned technical problems. Summary of the Invention

[0028] See Figures 1-3 As shown in this embodiment, the pretreatment system for improving bubble-type pore breakage in STS electroplating lines is characterized by comprising a degreasing tank 1, a hot water washing tank 2, a three-stage water washing tank 3, an acid pickling tank 4, a two-stage water washing tank 5, and a copper pre-acid pickling tank 64 arranged sequentially. The degreasing tank 1 and the copper pre-acid pickling tank 64 are respectively equipped with vibration components 7 to enhance chemical exchange within the pores. The three-stage water washing tank 3 is equipped with a spray component 8 to enhance the cleaning intensity.

[0029] This embodiment has a simple structure and reasonable design. During pretreatment, the degreasing tank 1 is used to remove oil stains, the hot water washing tank 2 is used to further clean and preheat the workpiece, the three-stage water washing tank 3 is used for multiple cleanings to ensure cleanliness, the pickling tank 4 is used to remove surface oxides, the two-stage water washing tank 5 is used for further cleaning, and the copper pre-pickling tank 64 is the last pickling treatment before electroplating. At the same time, the vibration component 7 set in the degreasing tank 1 and the copper pre-pickling tank 64 enhances the exchange of chemicals in the hole and improves the cleaning effect. In addition, the spray component 8 set in the three-stage water washing tank 3 enhances the cleaning intensity to achieve a better cleaning effect, thereby effectively improving the problem of bubble-type hole breakage in the STS electroplating line.

[0030] In some embodiments, the vibration assembly 7 is provided with a fixed base 71, a vibration motor 72 and a vibration plate 73. The fixed base 71 is disposed in the degreasing tank 1 / the copper pre-pickling tank 64, the vibration motor 72 is mounted on the fixed base 71, and the vibration plate 73 is connected to the fixed base 71 and extends into the degreasing tank 1 / the copper pre-pickling tank 64.

[0031] Specifically, the vibration motor 72 is configured as a roll-type and plate-type VCP vibration motor 72.

[0032] This embodiment specifically illustrates the structural configuration of the vibration component 7, which enables the vibration to be stably transmitted to the solution in the degreasing tank 1 or the copper pre-pickling tank 64, thereby effectively promoting the exchange of chemicals in the holes and improving the processing efficiency and effect. At the same time, by adopting the roll / plate type VCP vibration motor 72, which has a specific vibration mode and frequency, it is more suitable for the chemical exchange requirements in the pretreatment of the electroplating line, and can more effectively remove air bubbles and residues in the holes. Specifically, the power of the vibration motor 72 can be set to 2.2Kw to achieve a better cleaning effect.

[0033] In some embodiments, the spray assembly 8 is located at the first water washing position of the three-stage water washing tank 3.

[0034] In this embodiment, the spray assembly 8 is set at the first water washing position of the three-stage water washing tank 3, which can ensure that most of the residues have been removed by high-intensity spray cleaning before the workpiece enters the subsequent processing tank, providing a better foundation for subsequent processing and thus achieving a better cleaning effect.

[0035] In some embodiments, the spray assembly 8 is provided with a water tank 81, a conveying pipe 82 and a spray pipe 83. The water tank 81 is connected to the spray pipe 83 through the conveying pipe 82. A high-pressure pump body 84 is provided on the conveying pipe 82. The spray pipe 83 is located in the three-stage washing tank 3 and is provided with a plurality of spray nozzles 85.

[0036] Specifically, the spray pipe 83 is vertically fixed in the three-stage washing tank 3, and the multiple spray nozzles 85 are evenly distributed at intervals along the length of the spray pipe 83.

[0037] Specifically, the spray nozzle 85 is configured as a conical nozzle.

[0038] Specifically, the water tank 81 is equipped with a filter bucket 86.

[0039] In this embodiment, by setting a high-pressure pump body 84, it is possible to ensure that the cleaning fluid enters the spray pipe 83 and is sprayed in a high-pressure and high-flow manner. The spray pipe 83 is vertically fixed in the three-stage water washing tank 3, and the multiple conical nozzles of the spray pipe 83 are evenly distributed along their length. This arrangement can ensure that the cleaning fluid can evenly cover all parts of the workpiece, improving the cleaning effect. The filter barrel 86 is set in the water tank 81 to filter out impurities and particles in the cleaning fluid, ensuring the quality and cleanliness of the cleaning fluid, thereby further improving the cleaning effect. In addition, it can also avoid clogging of the pipes and extend the service life of the spray assembly 8.

[0040] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
