Description

Technical Field

[0001] This utility model belongs to the field of semiconductor device packaging and testing, and specifically relates to a fixture for fixing and mounting optical devices. Background Technology

[0002] Optical devices made of semiconductors have important applications in optical sensing technologies such as laser communication, data center optical networks, high-performance computing, and lidar. To improve device performance, microstructures are usually designed on both sides, and these microstructures directly determine the optical performance of the device (such as coupling efficiency and wavelength stability).

[0003] However, these microstructures are extremely vulnerable to damage during transportation, and due to their structural characteristics, they cannot be transported using blue film attachment methods, making it difficult for existing loading tools to meet the requirements for safe transportation.

[0004] Therefore, there is an urgent need for a special fixture that can effectively fix optical devices, protect microstructures, and is easy to operate. Summary of the Invention

[0008] The bottom shell has a number of elliptical holes, which are evenly distributed in a matrix.

[0009] Each of the elliptical holes has a square hole on each of its left and right sides;

[0010] The inner surface of the top cover is provided with an oxide protective layer, which is then placed over the bottom shell to fix the optical components.

[0011] The oxide protective layer of the bottom shell is formed into a black oxide film with a thickness of 5-8 μm through an anodic oxidation process.

[0012] The inner surface of the top cover has an oxide protective layer formed by anodizing, resulting in a black oxide film with a thickness of 8-12 μm.

[0013] The size of the elliptical hole is adapted to the optical device, and when the optical device is placed in the elliptical hole, it only contacts the sidewall of the elliptical hole through its four edges.

[0014] The major axis of the elliptical aperture is 0.1-0.3 mm larger than the length of the optical device, and the minor axis is 0.1-0.3 mm larger than the width of the optical device.

[0015] The square hole has a side length of 2-4 mm and a distance of 0.5-1.5 mm from the edge of the elliptical hole.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] A fixed mounting fixture for an optical device, such as Figure 1 As shown, it includes a bottom shell 2 and a top cover 1; the surface of the bottom shell 2 is provided with an oxide protective layer;

[0026] The bottom shell 2 has a plurality of elliptical holes 3, which are evenly distributed in a matrix.

[0027] Each of the elliptical holes 3 has a square hole 4 on each of its left and right sides;

[0028] The inner surface of the upper cover 1 is provided with an oxide protective layer, which is then covered by the bottom shell 2 to fix the optical device.

[0029] The major axis of the elliptical hole 3 is equal to the length of the optical device chip 5 plus 0.3 to 0.5 mm, and the minor axis is equal to the width of the optical device plus 0.2 to 0.4 mm. It can also be prepared according to the size ratio of the optical device chip 5 as needed.

[0030] The oxide protective layer of the bottom shell 2 is formed into a black oxide film with a thickness of 5-8 μm by anodizing.

[0031] The inner surface of the upper cover 1 is covered with an oxide protective layer formed by anodizing, resulting in a black oxide film with a thickness of 8-12 μm.

[0032] The black oxide layer has a hardness of ≥300HV, which can prevent the jig itself from wearing out and causing debris to fall off inside the fixed mounting jig, thus preventing damage to the optical chip 5.

[0033] The size of the elliptical hole 3 is adapted to the optical device, and when the optical device is placed in the elliptical hole 3, it only contacts the side wall of the elliptical hole 3 through its four edges.

[0034] The square hole 4 has a side length of 2-4 mm, and the distance between it and the edge of the elliptical hole 3 is 0.5-1.5 mm.

[0035] The square hole 4 is a countersunk hole on the surface of the bottom shell 2. It is used as a holding position for the end of the optical device chip 5. It can be conveniently fixed with a clamp (high-precision tweezers) or a vacuum pen to remove the optical device chip 5 from the elliptical hole 3.

[0036] The thickness of the bottom shell 2 and the top cover 1 is 1-3mm, and both the bottom shell 2 and the top cover 1 are made of aluminum alloy.

[0037] The length of the square hole 4 is greater than the width of the elliptical cavity, and the hole depth is 2-3 mm.

[0038] The inner wall of the elliptical hole 3 is integrally molded with silicone elastic cotton with a Shore hardness of 50-60 (embedded in the aluminum alloy base shell 2 through a molding process). The surface of the elastic cotton is treated with fluoride (low coefficient of friction ≤0.1), which can further absorb the vibration during transportation and at the same time prevent the edges of the device from being scratched by hard metal.

[0039] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
