[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0030] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "set" should be understood in a broad sense, for example, they can be fixedly connected or set, or detachably connected or set, or integrally connected or set. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The models of electrical appliances provided in the present utility model are only for reference, and different models of electrical appliances with the same functions can be replaced according to actual usage.
[0031] See also Figure 1-4 The utility model provides a technical solution: a manual sampling jig for chip products on substrates, comprising a jig body 1, magazine slot positioning piles 11 are fixed on both sides of one end of the jig body 1, a through hole is opened in the inner cavity of the jig body 1 and a transparent plate 12 is installed in the through hole, and fixing bars 15 are fixed on both sides of the inner cavity of the jig body 1;
[0032] Both sides of the bottom of the fixture body 1 are hinged with connecting blocks 13, and a pressure strip 14 is provided on the lower side of the fixture body 1. The tail end of the connecting block 13 is hinged with the corresponding position of the pressure strip 14;
[0033] In actual use, the pressure strip 14 is flipped to an open state in a direction away from the jig body 1, so that the substrate can be placed in, and the magazine slot positioning pile 11 is inserted into the machine magazine. At this time, the jig body 1 and the machine magazine slot are kept horizontal, and the substrate can be dragged from the machine magazine into the jig body 1 by tweezers to protect the product from being accidentally touched when it is taken out. After the substrate is dragged in, the chip will be supported by the two fixing strips 15, and then the pressure strip 14 is flipped to a closed state in a direction in contact with the jig body 1, completing the process of taking the chip product with wire bonding on the substrate out of the machine, flipping the jig body 1 as a whole, so that the back of the substrate can be seen, completing the process of flipping the sampling jig to check the back of the substrate, and then inserting the magazine slot positioning pile 11 into the machine magazine. At this time, the jig body 1 and the machine magazine slot are kept horizontal, and the pressure strip 14 is flipped to an open state in a direction away from the jig body 1, so that the substrate is released from the fixation in the jig body 1, and the substrate can be pushed into the machine magazine from the jig body 1 by tweezers.
[0034] Furthermore, mounting grooves are provided on both sides of one side wall of the fixture body 1, and support blocks 17 are fixed in the inner cavity of the mounting grooves, so that when the fixture body 1 is turned over so that the back side faces upward, the support blocks 17 can provide stable support to ensure that the fixture body 1 can be in a horizontal state for easy viewing.
[0035] Furthermore, a notch 16 is provided at one end of the fixture body 1. The notch 16 allows the tweezers to operate from the notch 16 when the substrate is pushed into the machine magazine, thus avoiding space obstacles.
[0036] It is worth mentioning that an end of the fixing strip 15 corresponding to the magazine slot positioning pile 11 is provided with an inclined surface, and the setting of the inclined surface ensures that there is no obstruction when the substrate is pushed into the fixture body 1.
[0037] It should be noted that fixed pressing plates 18 are embedded on the four sides of the back of the fixture body 1 . The provision of the fixed pressing plates 18 enables the installed transparent plate 12 to be limited in position, thereby ensuring the stability of the transparent plate 12 .
[0038] like Figure 1 and 2 As shown; a first magnet block is embedded on both sides of one side wall of the pressure strip 14, and a second magnet block is fixedly embedded on the outer wall of the fixture body 1 corresponding to the first magnet block, so that when the pressure strip 14 is turned over and closed on the fixture body 1, the first magnet block and the second magnet block are used for adsorption, so as to achieve the pressing of the substrate and ensure the stability of the substrate.
[0039] The implementation principle of the manual sampling jig for chip products on substrates of the present application is as follows: in actual use, the pressure strip 14 is flipped away from the jig body 1 to an open state, so that the substrate can be placed, and the magazine slot positioning pile 11 is inserted into the machine magazine. At this time, the jig body 1 and the machine magazine slot are kept horizontal, and the substrate can be dragged from the machine magazine into the jig body 1 by tweezers, so that the substrate moves along the inclined surface of the fixing strip 15 to ensure that the product movement is not blocked, and at the same time protect the product from being accidentally touched when it is taken out. After the substrate is dragged in, the chip will be carried by the two fixing strips 15, and then the pressure strip 14 is flipped to the direction in contact with the jig body 1. Flip it to the closed state, use the first magnet block and the second magnet block to adsorb, so as to achieve pressing the substrate to ensure the stability of the substrate, complete the process of taking the chip product with wire bonding on the substrate out of the machine, flip the fixture body 1 as a whole, so that the back of the substrate can be seen, and complete the process of flipping the sampling fixture to check the back of the substrate, and then insert the magazine slot positioning pile 11 into the machine magazine. At this time, the fixture body 1 and the machine magazine slot are kept horizontal, and the pressure strip 14 is flipped open in the direction away from the fixture body 1, so that the substrate is released from the fixture body 1. Push the substrate into the machine magazine from the fixture body 1 with tweezers.
