Abstract
Description
Technical Field
[0001] This application relates to the field of printed circuit board manufacturing technology, and in particular to a baking fixture and baking equipment for circuit boards. Background Technology
[0002] As the electronics industry rapidly evolves towards high-density integration, miniaturization, and multifunctionality, the reliability verification requirements for electronic components in printed circuit board (PCB) assembly processes are becoming increasingly stringent. Especially in consumer electronics such as smartphones, motherboards must undergo multiple rigorous verification processes, including process yield analysis, reliability testing, and stress testing. Among these, the baking process, as a key step in eliminating internal stress on the motherboard, detecting soldering defects, and evaluating the temperature resistance of materials, is widely used in both laboratory and mass production stages.
[0003] In existing technologies, baking fixtures need to be customized according to the motherboard size, layout, and testing requirements. With the acceleration of product iteration and the parallel mass production of multiple models, the types of baking fixtures corresponding to different motherboard specifications have exploded, leading to the following prominent problems: 1. Strong fixture specificity: A single fixture can only be adapted to a specific model or testing scenario, and cannot be reused across products, resulting in a waste of equipment resources; 2. Insufficient compatibility: Traditional fixtures have fixed structures and are difficult to adapt to motherboard size adjustments or new testing requirements, resulting in a prolonged cycle of repeated development; 3. High cost: The cost of customized fixture development and storage management increases linearly with the number of fixtures, restricting the company's goal of reducing costs and increasing efficiency.
[0004] Existing baking fixture technologies generally adopt a rigid design mode of "one plate, one fixture", which lacks strong compatibility and universal solutions, and has become a bottleneck restricting manufacturing enterprises from quickly responding to market demands and improving experimental efficiency.

[0020] Explanation of main component symbols
[0021]
[0022] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation
[0023] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the features in the embodiments of this application can be combined with each other.
[0024] The following description sets forth numerous specific details to provide a thorough understanding of the embodiments of this utility model. The described embodiments are only a portion, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of the embodiments of this utility model.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of this invention pertain. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.
[0026] Please see Figure 1 This application provides a baking fixture 100, which includes a first base plate 10 and a plurality of first support members 20. The first base plate 10 has a first surface 11, and the plurality of first support members 20 are fixed at intervals to the first surface 11. A placement area 10b is formed between adjacent first support members 20. The placement area 10b is used to place a circuit board 200, and the adjacent first support members 20 are used to confine the circuit board 200 within the placement area 10b.
[0027] Generally, the circuit board 200 is roughly in the shape of a flat cuboid, having two surfaces with a large surface area and four side surfaces connecting the two surfaces, the four side surfaces having a relatively small surface area. During placement, the circuit board 200 is placed with one side facing the placement area 10b (i.e., vertical placement). If the circuit board 200 is tilted, at least two adjacent first support members 20 provide left-right abutment against the two larger surfaces of the circuit board 200, thereby confining the circuit board 200 within the placement area 10b. This allows the circuit board 200 to be fixed to the first base plate 10 at an angle relative to the first surface 11, and it is not prone to positional movement. Of course, in some embodiments, the circuit board 200 may also be placed vertically within the placement area 10b and not in contact with the first support members 20.
[0028] In some implementation methods, please refer to the following: Figure 2 Some of the first support members 20 are arranged at intervals along the first direction X, and some of the first support members 20 are arranged at intervals along the second direction Y. The first direction X and the second direction Y intersect, making the arrangement of the first support members 20 more orderly and forming more placement areas 10b on the first surface 11 that can accommodate the circuit boards 200. Compared to placing the circuit boards 200 with a larger area facing the first base plate 10, placing the circuit boards 200 vertically in the placement area 10b allows the baking fixture 100 to accommodate more circuit boards 200 side by side at once, thereby improving drying efficiency. In this embodiment, the first direction X and the second direction Y are perpendicular to each other. In other embodiments, the first direction X may also be inclined to the second direction Y.
[0029] In some embodiments, the first support member 20 may be in the shape of a circular column, a square column, or the like. This application does not impose any special restrictions on the shape of the first support member 20.
[0030] In some embodiments, the first base plate 10 further has a second surface 12 opposite to the first surface 11. The first base plate 10 is provided with a first through groove 10a penetrating the first surface 11 and the second surface 12. The first through groove 10a is spaced apart from the first support member 20 and is distributed within or around the placement area 10b. The first through groove 10a penetrates the two opposing surfaces of the first base plate 10. On the one hand, this helps the first base plate 10 dissipate heat, reducing the possibility of deformation due to uneven heating. On the other hand, it facilitates the passage of drying media such as hot air, infrared rays, or microwaves in the baking equipment through the first base plate 10 and into contact with the circuit board 200 to be dried, allowing the drying media to contact the circuit board 200 to be dried more quickly and comprehensively, thereby improving drying efficiency.
[0031] In some embodiments, the first base plate 10 is provided with a plurality of first through slots 10a, some of which are arranged at intervals along a first direction X, and some of which are arranged at intervals along a second direction Y. Increasing the number of first through slots 10a and the orderly arrangement of the first through slots 10a helps to improve drying efficiency.
[0032] In this embodiment, the first through groove 10a is generally a straight strip-shaped hole, and the extending direction of the first through groove 10a is parallel or perpendicular to the arrangement direction of the first support member 20. This is just an example, and this application does not impose any special restrictions on the shape of the first through groove 10a.
[0033] In some implementation methods, please refer to the following: Figure 3 The baking fixture 100 also includes a second base plate 30 and multiple connectors 40. The connectors 40 are fixed to the first surface 11, and the multiple connectors 40 are used to connect the first base plate 10 and the second base plate 30. The multiple connectors 40 are located between the first base plate 10 and the second base plate 30. Through the connectors 40, a second base plate 30 can be added to the original first base plate 10. The second base plate 30 can also be used to place the circuit boards 200 to be dried. For example, the circuit boards 200 can be placed flat on the second base plate 30, increasing the number of circuit boards 200 that can be dried at one time and improving the drying efficiency.
[0034] In some embodiments, the first base plate 10 is provided with a plurality of mounting holes 10c, which penetrate the first surface 11 and are used for inserting and fixing the connector 40. The number of mounting holes 10c may be the same as the number of connectors 40, or the number of mounting holes 10c may be greater than the number of connectors 40, so as to allow for changing the position of connectors 40 or adding connectors 40.
[0035] In some embodiments, multiple connectors 40 are distributed around the perimeter of the support member. The distribution of connectors 40 around the first support member 20 can reduce the likelihood of connectors 40 interfering with the placement of the circuit board 200 on the first base plate 10. In this embodiment, mounting holes 10c are distributed around the perimeter of the first base plate 10 and surround the first support member 20 and the first through slot 10a; connectors 40 are inserted into and fixed in the corresponding mounting holes 10c.
[0036] In some embodiments, the connector 40 may be in the shape of a circular column, a square column, or a square plate. This application does not impose any special restrictions on the shape of the connector 40, as long as it can support and fix the first base plate 10 and the second base plate 30.
[0037] In some embodiments, the second base plate 30 has a third surface 31, and the baking fixture 100 further includes a plurality of second supports 50, which are spaced apart and fixed to the third surface 31. The plurality of second supports 50 further increases the space and number of circuit boards 200 that the baking fixture 100 can be used to place.
[0038] In some embodiments, the second base plate 30 further has a fourth surface 32 opposite to the third surface 31. The second base plate 30 is provided with a second through groove 30a, which penetrates the third surface 31 and the fourth surface 32. The second through groove 30a also allows drying media such as hot air, infrared rays, or microwaves in the baking equipment to directly pass through the second through groove 30a and come into contact with the circuit board 200 to be dried, so that the drying media can contact the circuit board 200 to be dried more quickly and more comprehensively, thereby improving drying efficiency.
[0039] In this embodiment, the shape and position of the second through groove 30a correspond to the first through groove 10a, which can increase the flow of the drying medium between the first bottom plate 10 and the second bottom plate 30 and improve the drying efficiency.
[0040] In some embodiments, the second base plate 30 is provided with a plurality of second through slots 30a, some of which are arranged at intervals along the first direction X, and some of which are arranged at intervals along the second direction Y.
[0041] In some embodiments, the first base plate 10 and the second base plate 30 can be made of high-temperature resistant plastic steel, whose main component is polyvinyl chloride. High-temperature resistant plastic steel has a low cost. This is just an example. This application does not impose special restrictions on the materials of the first base plate 10 and the second base plate 30. Appropriate materials can be selected according to actual design requirements.
[0042] In some implementations, new base plates and new connectors 40 may be added to the first base plate 10 and the second base plate 30 as needed to further increase the capacity of the baking fixture 100 to accommodate the circuit board 200.
[0043] This application also provides a baking apparatus, which includes the aforementioned baking fixture 100 and a heating source. The baking apparatus includes, but is not limited to, an electric heating drying oven, a high-temperature oven, an infrared oven, and a microwave oven.
[0044] The baking fixture 100 provided in this application allows for the vertical placement of circuit boards 200, increasing the space available for accommodating circuit boards 200 and the number of circuit boards 200 that can be accommodated. Furthermore, the baking fixture 100 is highly versatile and compatible, capable of accommodating circuit boards 200 of various shapes and specifications, eliminating the need to replace the corresponding baking fixture 100 with different circuit board models and specifications, thus saving on the purchase cost of the baking fixture 100.
[0045] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
