Description

Technical Field

[0001] This invention relates to the field of substrate fixture technology, and in particular to a cleaning fixture for chip mounting substrates and its usage method. Background Technology

[0002] In the integrated circuit manufacturing process, the cleaning process of the chip mounting substrate is crucial, as its cleanliness directly affects the reliability of chip mounting and the overall performance of electronic products. With the continuous increase in chip integration and the shrinking of chip size, the requirements for the surface cleanliness of the mounting substrate are becoming increasingly stringent. As a core tool that carries the substrate and assists in the cleaning operation, the performance of the cleaning fixture plays a decisive role. Currently, most traditional cleaning fixtures constrain the substrate by clamping and fixing it. When fixing the substrate, the contact area with the substrate is relatively large, which can easily leave indentations or stains on the substrate surface, affecting the cleaning effect and substrate quality. Therefore, a cleaning fixture is needed to facilitate the stability of the chip mounting substrate during the cleaning process.

[0003] For example, application number 202322055960.5 proposes a cleaning fixture for chip mounting substrates, comprising a housing; a support plate fixedly connected to the housing, with multiple corresponding clamping grooves fixedly connected to the support plate and the inner wall of the housing; an airbag fixedly connected to the clamping groove, with a clamping slider fixedly connected to the airbag and slidably connected to the clamping groove; and an extrusion plate slidably connected to the housing, forming an extrusion cavity with the extrusion plate, the bottom of the housing, and the inner wall of the housing, and a hollow cavity opened in the extrusion plate. This invention moves the extrusion plate towards the bottom of the housing, causing each substrate to slide downwards synchronously under its own weight until the through hole connects with one end of the U-shaped hole. Air from the extrusion cavity enters each airbag, causing the airbag to expand and push each clamping slider. Thus, each clamping slider can limit and clamp each substrate, facilitating thorough cleaning of the substrates subsequently.

[0004] However, currently, mainstream chip mounting substrate cleaning fixtures generally adopt an edge constraint fixing mechanism. The substrate edges are clamped and positioned by the clamping plate structure to ensure stability during the cleaning process. However, the shielding area formed after the clamping plate contacts the substrate will significantly hinder the full wetting and effective flow of the cleaning fluid, resulting in a cleaning blind spot on the substrate surface. In common processes such as ultrasonic cleaning and spray cleaning, this shielding prevents the cleaning fluid from directly acting on the clamped area, making it difficult to completely remove residual flux, solder balls and other contaminants. Summary of the Invention

[0005] This invention relates to a cleaning fixture for chip mounting substrates and its usage method. The fixture has a clamping plate. By adjusting the motor driving rod, gear and other components, the clamping plate can be changed from a rectangle to a parallelogram, thereby forcing the substrate to tilt. This allows the dead corners generated when the substrate is in contact to be fully exposed, so that the cleaning fluid and cleaning equipment can fully cover all parts of the substrate, effectively removing impurities and stains.

[0008] Preferably, the fixed inner frame is fixed to the bottom of the inner wall of the mounting groove; the two sets of inner adjustment grooves are connected by a circular groove; a driving gear is rotatably connected in the circular groove between the two sets of inner adjustment grooves; a synchronous insertion hole is provided in the middle of the driving gear; a driving rod is inserted into the synchronous insertion hole.

[0009] Preferably, the two sets of passive racks are respectively connected to the driving gears through toothed connections; the two sets of synchronous slides are respectively slidably connected to the corresponding inner adjustment grooves; the two sets of sliding base blocks are configured as T-shaped block structures, and the two sets of sliding base blocks are respectively provided with through holes for cooperating with the corresponding outer tie rods, and the two sets of sliding base blocks are respectively provided with springs.

[0010] Preferably, two sets of rectangular plates are fixedly connected to the inner sides of the two sets of reverse adjustment slides respectively; adjustment grooves are respectively opened on the rectangular plates of the two sets of reverse adjustment slides; a hand-operated top frame is fixedly connected to the top of the two sets of reverse adjustment slides respectively; three sets of side mounting grooves are respectively opened on the two sets of reverse adjustment slides; shaft holes are respectively connected to the six sets of side mounting grooves; the ends of the three sets of bottom support rods are respectively rotatably connected to the corresponding side mounting grooves.

[0011] Preferably, each of the two sets of top adjusting blocks is provided with a threaded rod; the two sets of top adjusting blocks are slidably connected in corresponding adjusting grooves; the two sets of top adjusting blocks are distributed vertically relative to each other; locking blocks are threadedly connected to the threaded rods of the two sets of top adjusting blocks; and two sets of mating holes are provided on the connecting vertical rod.

[0012] Preferably, the two sets of horizontal mounting frames are respectively arranged between the corresponding two sets of connecting vertical rods; the two sets of horizontal mounting frames are respectively provided with constraint insertion holes at equal intervals; the ends of the four sets of constraint insertion holes are respectively provided with expansion grooves; the four sets of expansion grooves are respectively connected to rectangular through holes.

[0013] Preferably, each of the four sets of telescopic grooves has a docking block slidably connected inside; each of the four sets of docking blocks has a spring; each of the four sets of docking blocks has a handle fixed to its upper and lower sides; each of the two sets of plate frames has a cylindrical insert rod for cooperating with the constraint insertion hole; and the torsion groove is opened below the corresponding plate slot.

[0014] Preferably, the method of use includes the following steps: 1. Insert the substrate vertically into the mounting slot of the card holder. At this time, the bottom support ball block in the bottom torsion groove of the card holder can rotate flexibly to adapt to the shape of the bottom of the substrate and provide stable support. Then, push the docking block so that it extends out of the telescopic groove and engages with the docking hole of the connecting vertical rod. At the same time, the cylindrical insert on the card holder is inserted into the constraint hole of the horizontal mounting frame. Through the cooperation of the docking block and the constraint hole, the connection between the horizontal mounting frame, the card holder and the connecting vertical rod is ensured to be stable, and the substrate is clamped and fixed in all directions. 2. After initial cleaning of the substrate, start the adjustment motor. The motor shaft drives the hexagonal prism rod to rotate, which in turn drives the gear to rotate. Since the two sets of passive racks and the gear are engaged by the locking teeth, when the gear rotates, the two sets of passive racks slide in opposite directions along the inner adjustment groove, driving the fixed synchronous slide to move. During the movement of the synchronous slide, the sliding base block is driven to slide through the outer restraint rod, realizing the initial adjustment of the lateral position of the reverse adjustment slide plate. This causes the locking plate to change from a rectangle to a parallelogram, and at the same time forces the substrate to tilt. During the tilting process, the dead corner position generated during contact is exposed to facilitate the subsequent cleaning process.

[0015] Beneficial effects In this invention, by adjusting the motor drive rod and gears, the clamping plate can be changed from a rectangle to a parallelogram, thereby forcing the substrate to tilt. This allows the dead corners generated when the substrate contacts to be fully exposed, enabling the cleaning fluid and cleaning equipment to fully cover all parts of the substrate, effectively removing impurities and stains. Compared with traditional fixed clamping methods, this significantly improves cleaning efficiency and cleanliness, ensuring the high-quality requirements of chip mounting substrates.

[0016] In addition, the sliding fit between the top adjustment block and the adjustment slide, as well as the fastening design of the locking block, can quickly and accurately adjust the clamping position for chip mounting substrates of different sizes. At the same time, the gear in the adjustment section drives the passive rack to realize the lateral position adjustment of the synchronous slide and the reverse adjustment slide, so that the fixture can be widely adapted to various specifications of substrates, greatly expanding the scope of application and reducing the cost for enterprises to change different fixtures due to differences in substrate size.

[0017] In addition, the external assembly provides stable support for the entire device through the cooperation of the base support frame and the mounting groove. The fixed inner frame of the adjustment section further enhances the stability of the internal structure. On this basis, the various components, such as the toothed connection between the passive rack and the driving gear, and the cooperation between the docking block and the docking hole, form a multi-dimensional stable connection system. This ensures that the device structure remains stable during the substrate clamping and cleaning process, effectively avoiding substrate damage or poor cleaning effect caused by shaking, and significantly improving the reliability of use.

[0041] This invention discloses a method for using a cleaning fixture for chip mounting substrates, comprising the following steps: 1. Insert the substrate vertically into the mounting slot 506 of the clamping frame 505. At this time, the bottom support ball block 508 in the bottom torsion groove 507 of the lower clamping frame 505 can rotate flexibly to adapt to the bottom shape of the substrate and provide stable support. Then, push the docking block 504 so that it extends out of the telescopic groove 503 and is inserted into the docking hole 405 of the connecting vertical rod 404. At the same time, the cylindrical insert on the clamping frame 505 is inserted into the constraint hole 502 of the horizontal mounting frame 501. Through the cooperation of the docking block 504 and the constraint hole 502, the connection between the horizontal mounting frame 501, the clamping frame 505 and the connecting vertical rod 404 is ensured to be stable, and the substrate is clamped and fixed in all directions. 2. After the substrate is initially cleaned, the adjustment motor 103 is started. The motor shaft drives the hexagonal rod-shaped drive rod 104 to rotate, which in turn drives the drive gear 203 to rotate. Since the two sets of passive racks 205 are engaged with the drive gear 203 through the snap ring, when the drive gear 203 rotates, the two sets of passive racks 205 slide in opposite directions along the inner adjustment groove 202, which drives the fixed synchronous slide 206 to move. During the movement of the synchronous slide 206, the sliding base block 208 is driven to slide through the outer binding rod 207, thereby realizing the initial adjustment of the lateral position of the reverse adjustment slide plate 301, so that the snap plate part 5 is changed from a rectangle to a parallelogram state, and at the same time, the substrate is forced to tilt. During the tilting process, the dead corner position generated during contact is exposed to facilitate the subsequent cleaning process.

[0042] The specific usage and function of this embodiment: In this invention, the adjusting motor 103 in the outer part 1 is installed at the middle position of the bottom of the mounting groove 101. The mounting groove 101 is stably supported by the bottom support frame 102. The fixed inner frame 201 is fixed to the bottom of the inner wall of the mounting groove 101. The driving rod 104 passes through the synchronous insertion hole 204 and is connected to the motor shaft of the adjusting motor 103, so that the driving gear 203 can rotate in the circular groove between the inner adjusting grooves 202 under the drive of the adjusting motor 103. According to the size of the substrate, the position of the top adjusting block 401 in the adjusting slide 302 is manually adjusted. The top adjusting block 401 cooperates with the locking block 403 through the threaded rod. After adjusting to the appropriate position, tighten the locking block 403 to fix the top adjustment block 401 in the adjustment groove 302. At this time, the connecting vertical rod 404 is rotatably connected to the top adjustment block 401 through the mating torsion groove 402, which can help constrain the horizontally distributed frame 501. At the same time, the position of the reverse adjustment slide 301 can be manually fine-tuned by pulling the top frame 303. The bottom support rod 305 rotates in the side mounting groove 304 to ensure stable support for the bottom of the substrate. Insert the substrate vertically into the plate mounting slot 506 of the plate holder 505. At this time, the bottom support ball block 508 in the bottom torsion groove 507 of the lower plate holder 505 can rotate flexibly to adapt to the shape of the bottom of the substrate. Providing stable support, the docking block 504 is then pushed, extending from the telescopic groove 503 and engaging with the docking hole 405 of the connecting vertical rod 404. Simultaneously, the cylindrical insert on the clamping plate frame 505 is inserted into the constraint hole 502 of the horizontal mounting frame 501. Through the cooperation of the docking block 504 and the constraint hole 502, a stable connection is ensured between the horizontal mounting frame 501, the clamping plate frame 505, and the connecting vertical rod 404, completing the all-round clamping and fixing of the substrate for subsequent cleaning and other processing. After the substrate is initially cleaned using external equipment, the adjusting motor 103 is started, and the motor shaft drives the hexagonal prism rod-shaped drive rod 104 to rotate. The movement drives the gear 203 to rotate. Since the two sets of passive racks 205 mesh with the driving gear 203 through the snap ring, when the driving gear 203 rotates, the two sets of passive racks 205 slide in opposite directions along the inner adjustment groove 202, causing the fixed synchronous slide 206 to move. During the movement of the synchronous slide 206, the sliding base block 208 is driven to slide through the outer restraint rod 207, realizing the initial adjustment of the lateral position of the reverse adjustment slide plate 301, thereby changing the snap ring part 5 from a rectangle to a parallelogram state, and forcing the substrate to tilt, so that the dead corner position generated during the tilting process is exposed to the outside, so as to facilitate the subsequent cleaning process.

9. A method of using a cleaning fixture for a chip mounting substrate, implemented according to claim 8, characterized in that: Includes the following steps: 1) Insert the substrate vertically into the mounting slot (506) of the mounting plate holder (505). At this time, the bottom support ball block (508) in the bottom torsion groove (507) of the lower mounting plate holder (505) can rotate flexibly to adapt to the bottom shape of the substrate and provide stable support. Then, push the docking block (504) so ​​that it extends out of the telescopic groove (503) and is inserted into the docking hole (405) of the connecting vertical rod (404). At the same time, the cylindrical insert on the mounting plate holder (505) is inserted into the constraint hole (502) of the horizontal mounting frame (501).
