Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology for packaging carriers, and in particular to a surface treatment device for FCOB packaging carriers. Background Technology

[0002] The field of FCOB (Flip Chip on Board) packaging substrate surface treatment technology mainly involves the processes and apparatus for surface treatment of substrates used in FCOB packaging during semiconductor packaging. This technology primarily covers various surface treatment methods, including gold plating, silver plating, tin plating, and oxide film treatment, to improve the conductivity, solderability, corrosion resistance, and other properties of the substrate. By optimizing surface treatment, the electrical performance and mechanical reliability of semiconductor devices can be effectively improved, meeting the requirements of high-speed, high-density circuits. Therefore, it is widely used in high-precision packaging fields such as microelectronics packaging and LED packaging.

[0003] CN213938460U discloses a PCB surface treatment device with a hot rod stirring mechanism, including a housing. A lead screw is rotatably mounted between the top and side walls of the inner cavity of the housing. A first servo motor is fixed to the top of the left wall of the housing. The power shaft of the first servo motor passes through the left wall of the housing and is fixedly connected to one end of the lead screw. A lead screw nut is mounted on the lead screw. A guide rail is fixed to the top wall of the inner cavity of the housing. A guide groove matching the guide rail is opened at the top of the lead screw nut. A hot rod stirring mechanism is fixed to the bottom of the lead screw nut through a connecting rod. A paint pump is mounted at the bottom of the hot rod stirring mechanism. The inlet pipe of the paint pump is connected to the bottom of the hot rod stirring mechanism. The outlet pipe of the paint pump is connected to a spray pipe. The spray pipe is fixed below the hot rod stirring mechanism by a mounting rod. Several nozzles are mounted at the bottom of the spray pipe. A clamping assembly is rotatably mounted in the middle of the inner cavity of the housing through a rotating shaft. A flipping assembly is mounted on the right wall of the housing corresponding to the position of the rotating shaft. While this surface treatment apparatus ensures the waterproof paint doesn't stick and harden through its heated agitation mechanism, guaranteeing a good coating effect, it suffers from drawbacks. This apparatus uses a motor-controlled clamping plate to hold the FCOB packaging carrier, and motor control systems typically involve high energy consumption, especially in continuous production environments. Furthermore, the motor and related electrical control systems require regular maintenance, including replacing worn parts and system adjustments, which not only increases operating costs but can also lead to production interruptions. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned in the background section.

[0005] The present invention adopts the following technical solution: an FCOB packaging carrier surface treatment device, comprising a housing, an electric push rod fixedly installed on the top surface of the housing, a connecting box installed at the output end of the electric push rod, a nozzle connected to the bottom end of the connecting box, a long rod extending through the side of the housing, a push block fixedly installed at one end of the long rod, a side block fixedly installed at the other end of the long rod, a tension spring fixedly installed between the side block and the housing, and a worktable fixedly installed on the inner wall of the housing.

[0006] Preferably, there are two sets of long rods, and the long rods are slidably connected to the box body.

[0007] Preferably, a door is rotatably connected to the surface of the enclosure, and a door handle is fixedly installed on the surface of the door.

[0008] Preferably, the bottom surface of the box is fixedly equipped with support legs, and the support legs are evenly distributed at the four corners of the bottom surface of the box.

[0009] Preferably, the inner wall of the workbench is provided with a protective mechanism, the protective mechanism including a horizontal groove, the horizontal groove being formed in the inner wall of the workbench, a horizontal bar being fixedly installed on the inner side of the housing, a vertical plate being slidably connected to the surface of the horizontal bar, a protective block being fixedly installed at the top of the vertical plate, a rubber plate being fixedly installed on the side of the vertical plate, a double-acting screw being rotatably connected to the inner wall of the workbench, a sliding rod being fixedly installed on the inner wall of the workbench, and two limiting plates being sleeved on the surface of the sliding rod and the double-acting screw.

[0010] Preferably, the limiting plate has internal threads that mesh with a bidirectional lead screw.

[0011] Preferably, the limiting plate is slidably connected to the slide rod, and the surface of the bidirectional lead screw is provided with a left-hand thread near one end and a right-hand thread near the other end.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. This utility model utilizes a mechanical linkage mechanism of tension springs and side blocks to quickly place and fix FCOB packaging carriers onto the worktable. This rapid positioning and fixing mechanism reduces manual operation time and labor intensity while improving processing efficiency. Furthermore, the entire fixing process does not require complex manual adjustments; the user simply places the carrier on the worktable, and the relevant mechanical structure automatically completes the clamping work. This simplified operation process makes the equipment more user-friendly, especially suitable for production environments that need to process a large number of carriers. Moreover, this design can adapt to FCOB packaging carriers of different sizes and thicknesses, which increases the equipment's versatility, allowing the same equipment to be used on multiple product lines and reducing the company's investment costs in equipment.

[0014] 2. This utility model uses a protective block to enclose the spray head. This function is automatically implemented when the equipment is idle, reducing the possibility of the spray head being damaged by dust, contaminants, or mechanical damage. This not only extends the service life of the spray head but also maintains the quality and precision of the spraying process. Furthermore, the design of the bidirectional screw allows for precise adjustment of the limit plate. The vertical plate and rubber plate can be precisely controlled through a simple rotation operation. This adjustment method is not only easy to operate but also allows for very precise adjustment according to the size and position of the FCOB packaging carrier. Thus, when placing the FCOB packaging carrier, the operator does not need to perform complex settings or make large-scale movements of the push block and rubber plate, because the positions of the relevant components have been pre-adjusted by the bidirectional screw. This reduces the operator's physical labor, shortens the equipment adjustment time, and improves the overall operating efficiency. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] Please see Figure 1-4 This utility model provides a technical solution: a surface treatment device for FCOB packaging carrier plates, including a housing 1. Supports are fixedly installed on the bottom surface of the housing 1, and the supports are evenly distributed at the four corners of the bottom surface of the housing 1. The supports are connected to the housing 1 by bolts or welding to ensure the stability and reliability of the equipment during operation. The supports can be made of stainless steel or high-strength plastic. Stainless steel has excellent corrosion resistance, while high-strength plastic has the advantages of light weight and low cost. A door 2 is rotatably connected to the surface of the housing 1, and a door handle is fixedly installed on the surface of the door 2. The door handle is made of durable metal material, ensuring long-term durability and ease of operation. An electric push rod 3 is fixedly installed on the top surface of the housing 1. A connecting box 4 is installed at the output end of the electric push rod 3. The connecting box 4 is connected to a waterproof paint source. Through the control of the electric push rod 3, the spray nozzle 5 can be precisely raised and lowered, improving spraying efficiency and accuracy. The bottom of the connecting box 4 is connected to a nozzle 5. After the waterproof paint enters the connecting box 4, it can be sprayed out through the nozzle 5 for waterproof coating of the FCOB packaging carrier.

[0025] Please see Figure 1-4 Two sets of long rods 6 are installed through the side of the housing 1. The long rods 6 are slidably connected to the housing 1 using either guide rails or bearings to achieve a smooth and adjustable sliding effect. A push block 7 is fixedly installed at one end of each long rod 6, and a side block 8 is fixedly installed at the other end. A tension spring 9 is fixedly installed between the side block 8 and the housing 1. The tension spring 9 is a high-elasticity steel spring with good elasticity and restoring force. When the FCOB packaging carrier is placed on the worktable 10, the tension of the tension spring 9 pulls the side block 8, which in turn moves the long rods 6 and the push block 7. The push block 7 presses against the FCOB packaging carrier, quickly fixing it onto the worktable 10. This mechanical linkage mechanism reduces manual operation time and labor intensity while improving processing efficiency. The worktable 10 is fixedly installed on the inner wall of the housing 1.

[0026] Example 2

[0027] Please see Figure 3-4The inner wall of the workbench 10 is equipped with a protective mechanism, which includes a horizontal groove 11. A horizontal bar 12 is fixedly installed on the inner side of the housing 1. A vertical plate 13 is slidably connected to the surface of the horizontal bar 12. A protective block 14 is fixedly installed at the top of the vertical plate 13, and a rubber plate 15 is fixedly installed on the side of the vertical plate 13. When there is no FCOB packaging carrier plate on the workbench 10, the push block 7 can push the vertical plate 13 to move due to the tension of the tension spring 9. The vertical plate 13 slides on the surface of the horizontal bar 12, simultaneously driving the protective block 14 to move. The protective block 14 can cover the nozzle 5, thus protecting the nozzle 5 when not in operation. A double-acting screw 16 is rotatably connected to the inner wall of the workbench 10. The surface of the double-acting screw 16 has a left-hand thread near one end and a right-hand thread near the other end, which can realize the opposite or opposite movement of the limiting plate 18 to adjust its position. A slide rod 17 is fixedly installed on the inner wall of the workbench 10. Two limiting plates 18 are fitted on the surfaces of the slide rod 17 and the double-acting lead screw 16. The limiting plates 18 have internal threads that mesh with the double-acting lead screw 16, and the limiting plates 18 are slidably connected to the slide rod 17. This design allows the limiting plates 18 to be precisely adjusted, and the positions of the vertical plate 13 and the rubber plate 15 can be precisely controlled by a simple rotation operation. Thus, when placing the FCOB packaging carrier, the operator does not need to perform complex settings or make large movements of the push block 7 and the rubber plate 15, reducing the operator's physical labor, shortening the equipment adjustment time, and improving the overall operating efficiency.

[0028] Working Principle: A waterproof paint source is connected to the connecting box 4. After the waterproof paint enters the connecting box 4, it can be sprayed out through the nozzle 5. Then, the FCOB packaging carrier is placed on the worktable 10. At this time, the FCOB packaging carrier can be waterproofed by spraying through the nozzle 5. Simultaneously, after the FCOB packaging carrier is placed on the worktable 10, the tension of the tension spring 9 pulls the side block 8 to move. The side block 8 then drives the long rod 6 to move, and the long rod 6 then drives the push block 7 to move. The push block 7 can then press the FCOB packaging carrier, thus fixing the FCOB packaging carrier on the worktable 10. This utility model, through the mechanical linkage mechanism of the tension spring 9 and the side block 8, can quickly place and fix the FCOB packaging carrier on the worktable 10. The rapid positioning and fixing mechanism reduces manual operation time and labor intensity while improving processing efficiency. The entire fixing process requires no complex manual adjustments; the user simply places the carrier plate on the worktable 10, and the relevant mechanical structure automatically completes the clamping work. This simplified operation makes the equipment more user-friendly, especially suitable for production environments that need to process large numbers of carrier plates. Furthermore, this design can adapt to FCOB packaging carrier plates of different sizes and thicknesses, increasing the equipment's versatility and allowing the same equipment to be used on multiple product lines, reducing the company's investment costs. When no FCOB packaging carrier plate is placed on the worktable 10, the push block 7 can push the vertical plate 13 to move due to the tension of the tension spring 9. The vertical plate 13 is then positioned on the horizontal bar 12. The surface slides, and the vertical plate 13 drives the protective block 14 to move. The protective block 14 can then wrap around the nozzle 5. In this way, when not in operation, the protective block 14 can wrap and protect the nozzle 5, thereby reducing the probability of foreign objects entering the nozzle 5. At the same time, when the FCOB packaging carrier is placed for processing, the operator can also turn the bidirectional lead screw 16. Since the threads on the surface of the bidirectional lead screw 16 are opposite, it can drive the limiting plate 18 to move in opposite directions or towards each other. This can adjust the position of the limiting plate 18, which in turn drives the vertical plate 13 to move. The vertical plate 13 can then drive the rubber plate 15 to move, thus controlling the approximate position of the rubber plate 15. In this way, when the FCOB packaging carrier is placed, it is not necessary to push the pusher block 7 significantly. The nozzle 5 is encased by a new type of protective block 14, a function that automatically operates when the equipment is idle. This reduces the possibility of the nozzle 5 being damaged by dust, contaminants, or mechanical damage, extending its service life and maintaining the quality and precision of the spraying process. Furthermore, the design of the bidirectional lead screw 16 allows for precise adjustment of the limiting plate 18, enabling accurate control of the vertical plate 13 and rubber plate 15 through simple rotation. This adjustment method is not only easy to operate but also allows for highly precise adjustment based on the size and position of the FCOB packaging carrier. Thus, when placing the FCOB packaging carrier, the operator does not need to perform complex settings or make significant movements of the push block 7 and rubber plate 15, as the positions of the relevant components have already been pre-adjusted by the bidirectional lead screw 16.This reduces the physical workload of operators, shortens equipment setup time, and improves overall operational efficiency.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
