[0041] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the attached drawings in the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0042] The following combines the attached Figures 1 to 8The following embodiments are used to further describe the implementation manners of the present utility model in detail. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0043] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the laser die bonding, chip mounting and detection fixture provided by the embodiment of the present utility model specifically includes a chassis 1 and a strip 2.

[0044] The chassis 1 is provided with a first mounting position 11 and a second mounting position 12, and both the first mounting position 11 and the second mounting position 12 are used to fix the strip 2. In a preferred example, in order to improve the chip mounting efficiency, as Figure 4 shown, both the first mounting position 11 and the second mounting position 12 are multiple.

[0045] The strip 2 is provided with a strip body 21, a baffle 22, a fixed manganese sheet 23 and a strong magnetic part 24; the fixed manganese sheet 23 is arranged at the top of the strip body 21 and is used to mount the product socket 3; the strong magnetic part 24 is arranged at the bottom of the strip body 21 and is used to adsorb and fix the product socket 3; the baffle 22 is arranged at the bottom of the strip body 21.

[0046] As Figure 8 shown, the product socket 3 includes a sector column 31 and a 7° inclined groove 32, which are respectively used for die bonding, chip mounting and inspection of an optical communication laser and a gas sensing laser.

[0047] When the strip 2 is arranged at the first mounting position 11, as Figure 1 and Figure 5 shown, the strip 2 is in a horizontal state relative to the chassis 1, so that the side surface (horizontal plane) of the sector column 31 of the product socket 3 is horizontally upwardly arranged for die bonding, chip mounting and inspection of an optical communication laser.

[0048] When the strip 2 is arranged at the second mounting position 12, as Figure 3 、 Figure 5 and Figure 6 shown, the strip 2 is in a vertical state relative to the chassis 1, so that the 7° inclined groove 32 of the product socket 3 is horizontally upwardly arranged for die bonding, chip mounting and inspection of a gas sensing laser.

[0049] Among them, in an optional embodiment, the top of the strip body 21 is provided with a first hole position, and the fixed manganese sheet 23 is provided with a second hole position; the first hole position and the second hole position are correspondingly arranged, and the first hole position and the second hole position are used to be adapted to the mounting position of the product socket 3.

[0050] Preferably, in order to further improve the chip mounting efficiency, both the first hole position and the second hole position are multiple, and the specific number of the hole positions is not limited and can be correspondingly set according to actual needs.

[0051] It should be noted that in the first case, as Figure 1 shown, when the laser for gas sensing is die-bonded and pasted, the strip 2 is located at the first mounting position 11, and the strip 2 is in a horizontal shape at the first mounting position 11.

[0052] As Figure 7 shown, the chassis 1 is provided with a stop portion 13. As Figure 5 shown, the strip body 21 is provided with a protrusion 211. As Figure 1 shown, the stop portion 13 and the protrusion 211 are arranged in abutment.

[0053] In actual operation, the corresponding operations are as follows:

[0054] 1. Place the product socket 3 on the corresponding hole positions of the strip 2. The strip body 21 and the fixed manganese sheet 23 are used to position the direction of the socket, and the socket is tightly attracted by the strong magnetic part 24.

[0055] 2. Horizontally place the strip 2 at the first mounting position 11 on the chassis 1. After the socket is fixed, the side of the socket sector column 31 faces horizontally upward. As Figure 2 shown, the edge of the chassis 1 just abuts against the back of the socket sector column 31 ( Figure 8 the arc surface of the sector column 31 in ), so that the sockets on the strip 2 are on the same horizontal plane, ensuring that the die-bonding and pasting can be carried out smoothly.

[0056] In the second case, as Figure 3 and Figure 4 shown, when the laser for the optical communication industry is die-bonded and pasted, in the case where the strip 2 is located at the second mounting position 12, as Figure 4 shown, the strong magnetic part 24 is arranged at the bottom of the strip body 21.

[0057] Among them, as Figure 7 shown, the second mounting position 12 is a strip-shaped groove, and the bottom of the strip-shaped groove is provided with a slope of 7°, so that when the strip 2 is placed in the strip-shaped groove, the 7° inclined groove 32 surface of the product socket 3 is horizontal.

[0058] In actual operation, the corresponding operations are as follows:

[0059] 1. Place the product socket 3 on the corresponding hole positions of the strip 2. The strip body 21 and the fixed manganese sheet 23 are used to position the direction of the socket, and the socket is tightly attracted by the strong magnetic part 24. Among them, the manganese sheet of the strip 2 is non-magnetic, which is convenient for the socket to be placed into the hole positions of the strip 2.

[0060] 2. Vertically place the strip 2 on the chassis 1. Since the vertical slot of the strip 2 on the chassis 1 is inclined at 7°, after the socket is fixed, the 7° inclined groove 32 of the socket faces horizontally upward and is on the same horizontal plane, so that the die-bonding and pasting can be carried out smoothly.

[0061] It should be noted that if the product bonding surfaces are not on the same plane, it will affect the bonding accuracy.

[0062] In addition, in the above two cases, when measuring the bonding position accuracy and chip thrust during the die bonding and chip bonding process, the strip 2 in the vertical or horizontal placement is removed, and the strip 2 with the socket fixed can be directly used for accuracy measurement and chip thrust detection without transferring the product to other fixed jigs for sampling measurement.

[0063] Furthermore, in an alternative embodiment, to ensure the firmness of the connection, as Figure 1 shown, the fixture further includes a first fastener and a second fastener.

[0064] Specifically, the first fastener is disposed at the top of the strip body for connecting and fastening the fixing manganese sheet 23 and the strip body, and the second fastener is disposed at the bottom of the strip body for connecting and fastening the baffle 22 and the strip body.

[0065] In summary, the die bonding, chip bonding and detection fixture for a laser proposed in the embodiment of the present invention can be compatibly applied to the fixing of different bonding surfaces of die bonding and chip bonding of the socket of lasers in the optical communication industry and lasers for gas sensing. When die bonding and chip bonding two types of lasers, only one set of fixtures is needed. At the same time, it can also be used for fixing the measurement of the bonding position accuracy and chip thrust during the die bonding and chip bonding process of the product, improving the efficiency of bonding and detection.

[0066] In the description of this specification, the description with reference to terms such as "specific examples" or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the embodiments of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
