[0017] Additionally, the terms "first" and "second" are for descriptive purposes only and should not be understood as indicating or suggesting the relative importance or quantity of the indicated technical features. Thus, a feature qualified as "first" or "second" may explicitly or implicitly include one or more of the feature.

[0018] In the description of this application, unless otherwise clearly and specifically limited, "several" and "plurality" mean two or more than two. In this application, unless otherwise clearly defined and limited, the terms "attached," "coupled," "connected," "fixed," etc. should be understood broadly, and may refer to, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, or internal communication between two elements.

[0019] Those skilled in the art will understand the specific meanings of the above terms in this application depending on the specific circumstances.

[0020] In this application, unless otherwise clearly defined and limited, a first feature being "above" or "below" a second feature may mean that the first feature and the second feature are in direct contact with each other, or may mean that the first feature and the second feature are not in direct contact with each other but are in contact with each other via another feature therebetween.

[0021] Furthermore, a first feature being "above," "above," and "above" a second feature includes the first feature being directly above or diagonally above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. A first feature being "below," "below," and "below" a second feature includes the first feature being directly below or diagonally below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0022] In view of the technical problems existing in the background art, a chip mounting jig is provided as shown in Figures 1 to 3, which includes a jig body 1, in which chip grooves 2 are provided that are uniformly distributed in an array for accommodating chips, and inwardly recessed wire grooves 3 are provided at the positions of the chip grooves 2, and the wire grooves 3 extend to the outside of the chip grooves 2.

[0023] In this embodiment, the chip groove 2 is recessed to a certain depth along the end face of the jig body 1, the depth of this recess being based on the thickness of the chip, and the chip grooves 2 are arranged on the jig body 1 so as to be distributed in an array. At the same time, the four corners of the chip groove 2 are designed to have rounded corners, thereby preventing the four corners of the chip from being damaged during processing.

[0024] To facilitate removal of the chips after machining, wire grooves 3 are designed at the positions of the chip grooves 2, and each chip groove 2 is designed with a wire groove 3, the length of the wire groove 3 extending to the outside of the chip groove 2. Alternatively, the wire grooves 3 between the chip grooves 2 on the same line can be connected.

[0025] 4 and 5, the chip mounting jig includes a stopper piece 4 attached to the jig body 1, and the stopper piece 4 is provided with one or more solder paste grooves 5 that fit into the chip grooves 2. The stopper piece 4 is used to apply solder paste to specific positions on the chip to form a solder paste belt, and is therefore added to improve the accuracy and quality of the solder paste application.

[0026] In the following embodiment, there are two solder paste grooves 5 corresponding to the position of the chip groove 2, and the two solder paste grooves 5 are arranged adjacent to each other and are offset from each other, i.e., the solder paste grooves 5 are arranged front to back with a certain distance between adjacent solder paste grooves 5. A pressing belt 6 is formed on the upper surface of the stopper piece 4, and during use, the pressing belt 6 is arranged across the chip groove 2, thereby applying pressure to the chip on the chip groove 2 and further fixing the chip in the chip groove 2.

[0027] The stopper piece 4 is magnetically attracted and fixed to the jig body 1 by magnetic attraction. A magnetic attraction structure can be designed on the stopper piece 4 and the jig body 1, and the stopper piece 4 can be quickly attached to the jig body 1 by magnetic attraction, improving work efficiency.

[0028] As shown in Figures 6 to 8, the chip mounting jig includes a stopper jig 7, which is provided with one or more needle grooves 8 that fit into the chip groove 2 and into which straight or square needles are placed.

[0029] In practice, the stopper jig 7 restricts the straight or square needle, and the needle groove 8 has a through structure. In use, the square or straight needle moves into the designated needle groove 8 through the action of surface mount technology (SMT), and the square or straight needle passes through the needle groove 8 to engage with the chip coated with solder paste below. As shown in FIG. 9, the chip product is produced in the above jig.

[0030] The following provides an actual operating process using the above-mentioned chip mounting jig, which includes a jig body 1, a stopper piece 4, and a stopper jig 7. The jig body 1, the stopper piece 4, and the stopper jig 7 have positioning holes drilled in their four corners, pins are provided in the four corners of the stopper jig 7, pin holes corresponding to the four corners of the stopper piece 4 are provided, positioning posts are provided in the four corners of the jig body 1, and the pins of the stopper jig 7 pass through the pin holes in the stopper piece 4 and engage with the positioning posts of the jig body 1 to be fixed.

[0031] A magnetic member having magnetic properties is attached to the jig body 1, and the stopper piece 4 can be engaged with the jig body 1 by magnetic fixation, and the jig body has four concave hand grooves to facilitate movement.

[0032] During use, the chip is placed in chip groove 2 on jig body 1, stopper piece 4 is magnetically attached to jig body 1, solder paste is applied to the chip pad surface through solder paste groove 5 in stopper piece 4 to form a solder paste belt, and pressure belt 6 formed between solder paste grooves 5 presses against the chip (since the solder paste belt for this chip includes two solder paste belts, two solder paste grooves 5 are required). Stopper jig 7 is then placed on stopper piece 4, and a straight or square needle is placed in needle groove 8 using surface mount technology (SMT) to adhere to the solder paste belt and complete the mounting. The completed chip is then removed from the jig. Needle groove 8 is designed to open gradually, making it easy to attach the straight or square needle.

[0033] The above operation process is different from the traditional mounting process, which allows for more accurate application of solder paste, more accurate mounting position, and improved overall quality of the processed chips.

[0034] The above does not limit the technical scope of the present invention, and any modifications, equivalent substitutions and alterations made to the above embodiments based on the technical essence of the present invention belong to the scope of the technical solutions of the present invention.
