Description

Technical Field

[0001] The present application relates to the technical field of infrared refrigeration detectors, and in particular to a bottom filling tool and a tooling pick-and-place assembly. Background Art

[0002] Infrared focal plane detectors (FPDs) offer advantages such as high sensitivity, good environmental adaptability, strong anti-interference capabilities, light weight, and low power consumption. They are widely used in aerospace infrared remote sensing, defense, meteorology, environmental protection, medicine, and scientific instrumentation. In the field of monochromatic detection, indium antimonide (InSb) FPDs offer outstanding performance in terms of production cost, pixel uniformity, and consistency.

[0003] During the manufacturing process of an InSb focal plane detector chip, the InSb photosensitive array and the silicon readout circuit must be interconnected. To ensure the reliability and stability of this interconnection, a layer of low-temperature adhesive is placed on the bottom of the chip. This adhesive securely bonds the InSb photosensitive array to the silicon readout circuit while also providing vibration dampening, moisture resistance, and anti-static properties.

[0004] The process of filling with low-temperature adhesive is called underfill, and it can improve the performance and reliability of infrared focal plane detectors. A dispenser is commonly used for underfill. During dispensing, the chip is typically placed on an underfill fixture using tweezers and then removed using tweezers after filling. This tweezers-based handling method carries the risk of chip chipping and dropping. Utility Model Content

[0039] See also Figure 1 In a first aspect of the embodiments of the present application, a bottom filling tool is provided, including: a tool body 10.

[0040] The tooling body 10 is provided with a filling structure. The filling structure includes an outer trough 11 and an inner trough 12. The first portion of the inner trough 12 is disposed within the outer trough 11, and the second portion extends outside the outer trough 11. A step 13 is formed between the outer trough 11 and the inner trough 12. Step 13 is used to place the chip.

[0041] The inner tank 12 is used for the film taker 20 to extend into the outer tank 11. In this embodiment, the film taker 20 can be as follows Figure 2 As shown, specifically, the film taker 20 can extend through the inner tank body 12 to the bottom of the outer tank body 11 .

[0042] With the filling structure provided by this solution, when placing a chip, the chip can be placed directly into the step 13. When removing the chip, the chip remover 20 extends through the second portion of the inner tank 12 into the first portion of the inner tank 12, that is, extends under the chip, and then the chip can be lifted up by the chip remover 20. In this way, whether the chip is picked up with tweezers or lifted up by the chip remover 20, the chip can be removed, and compared with the method of directly removing the chip from the outer tank 11 with tweezers, damage to the chip can be reduced.

[0043] In a more specific embodiment, notched grooves 14 are provided at the groove edge and / or end corner regions of the outer groove body 11 .

[0044] The notch groove 14 can facilitate chip placement and can be used for glue dispensing.

[0045] Optionally, the filling structure includes multiple filling structures; the multiple filling structures are distributed in an array, so that the bottom filling tool can dispense glue for multiple chips at the same time, thereby improving work efficiency.

[0046] As an embodiment, the filling structures are arranged in two symmetrical rows; the second portion of the inner tank body 12 is located outside the first portion of the inner tank body 12. The inner side of the inner tank body 12 refers to the side close to the other filling structure, which makes it easier to load and unload the film remover 20.

[0047] In application, the tool body 10 is provided with a number 15 corresponding to each filling structure. In addition, multiple rows of filling structures can also be numbered.

[0048] In a more specific embodiment, the first portion of the inner tank body 12 passes through the outer tank body 11 , so that the chip remover 20 extending into the first portion of the inner tank body 12 can be completely located directly below the chip.

[0049] In one embodiment, the inner groove body 12 is a strip-shaped groove; the filling structure includes a plurality of inner groove bodies 12 arranged in parallel.

[0050] The plurality of inner grooves 12 can increase the contact area between the chip remover 20 and the chip, thereby further reducing damage to the chip during chip removal.

[0051] See also Figure 1 and Figure 2 In a second aspect, the present application provides a tooling pick-and-place assembly, comprising: a film picker 20 and any of the above-mentioned bottom filling tooling.

[0052] In a more specific embodiment, the film extractor 20 includes a handheld end 21 and an insertion end 22; the handheld end 21 and the insertion end 22 are connected to each other to form an L-shaped structure; the insertion end 22 is used to extend from the second part of the inner tank body 12 to the first part of the inner tank body 12.

[0053] When placing the chip, the chip can be placed on the insertion end 22, and then the insertion end 22 is placed in the second part of the inner groove 12, so that the chip falls into the outer groove 11, and then the handheld end 21 drives the insertion end 22 to descend, so that the chip remover 20 is separated from the chip.

[0054] When taking out the chip, the insertion end 22 is placed in the first part of the inner groove 12, and then the handheld end 21 is used to drive the chip remover 20 to slide, so that the insertion end 22 slides to the second part of the inner groove 12, that is, directly below the chip. Then, the insertion end 22 is driven to rise, and the chip can be lifted out, completing the chip removal.

[0055] As a further improvement, the film retrieval device 20 includes multiple insertion ends 22; the filling structure includes multiple parallel inner grooves 12; the multiple insertion ends 22 are arranged in parallel and spaced apart; during the film retrieval process, the insertion ends 22 correspond one-to-one to the multiple inner grooves 12.

[0056] The multiple protruding ends 22 can increase the contact area with the chip and improve the stability of the chip taking and placing process.

[0057] The above are only preferred embodiments of the present application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the aforementioned examples or make equivalent replacements for some of the technical features therein.
