Description

Technical Field

[0001] The utility model relates to a power-up device for a semiconductor device, belonging to the technical field of semiconductor packaging. Background Art

[0002] Silicon photonics coupling technology is the process of connecting and integrating different optical components (such as lasers, optical fibers, etc.) with silicon photonics chips. Figure 1 As shown in FIG, it includes an optical fiber array 100, a silicon photonic chip 101, a lens 102, and a laser assembly 103. The coupling method requires coupling the entire optical fiber array 100 and the silicon photonic chip 101, fixing the laser assembly 103 and the silicon photonic assembly on the substrate 104, and positioning them according to the parameters of the lens. At the same time, the power supply position of the laser assembly 103 is bonded with gold wire or connected with a probe, and finally coupling the lens 102 located between the silicon photonic chip 101 and the laser assembly 103. With the development of device miniaturization, the lens 102 is removed from its structure, as shown in FIG. Figure 2 As shown, this structure has high requirements for the coupling process, and conventional coupling methods cannot be used.

[0003] A feasible coupling process is to couple the optical fiber array 100 with the silicon photonic chip 101, then glue and fix the laser component 103 to the substrate 104, and connect the positive and negative electrodes to the power supply. Then, clamp the coupled silicon photonic component and the laser component 103 to couple them, and after the coupling is completed, glue and fix them with transparent glue. This method is very easy to move and lose value during the coupling curing process because the coupled silicon photonic component is relatively large and the optical fiber array 100 will have a downward force. The coupling yield is relatively low and it is difficult to achieve mass production.

[0004] Another coupling process involves coupling the fiber array 100 to the silicon photonic chip 101, then securing the coupled silicon photonic components to a fixture. The laser component 103 is then clamped and coupled to the silicon photonic chip 101, and then bonded with a transparent adhesive. This process requires the laser component 103 to be powered while being moved and coupled. Once the coupling is complete, the power supply can be removed. Utility Model Content

[0022] The present invention will be further described below with reference to the following embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading this description, various equivalent modifications to this description by those skilled in the art fall within the scope defined by the claims attached to this application.

[0023] Please combine Figures 3 to 5 As shown, the power supply device for the laser assembly of this embodiment mainly comprises two parts: a base 1 and a swing arm 2. The base 1 serves as the foundation of the entire device, and a resilient clamping mechanism is provided at its front end. This resilient clamping mechanism is designed to laterally clamp the laser assembly 3, ensuring its stability during the coupling process.

[0024] The elastic clamping mechanism includes a fixed notch 1a fixed to the base 1 and a matching transverse telescopic member. The transverse telescopic member includes a fixed block 4, a clamping block 5, a guide rod 6, and a clamping spring 7. The fixed block 4 is fixedly connected to the base 1, the guide rod 6 is arranged horizontally and connected to the fixed block 4, and the clamping block 5 and the clamping spring 7 are sleeved on the guide rod 6. The clamping spring 7 is located between the clamping block 5 and the fixed block 4. Under the action of the clamping spring 7, the clamping block 5 can be tightly matched with the fixed notch 1a, thereby achieving a stable clamping of the laser assembly 3. It should be noted that the clamping block 5 should be designed accordingly according to the shape of the laser assembly 3 to be coupled to ensure stable clamping. The fixed block 4 is connected to the base 1 by screws. When different laser assemblies 3 need to be electrically coupled, this can be achieved by replacing different transverse telescopic members.

[0025] In addition, the depth of the fixing notch 1a should not be too deep, which ensures that part of the structure of the laser assembly 3 can still protrude from the end side of the base 1 in the clamped state, which is convenient for subsequent operations.

[0026] A swing arm 2 is connected to the base 1, and a power probe 8 is mounted on the swing arm 2. Power is applied to the laser assembly 3 via the power probe 8. Specifically, the base 1 is also provided with an articulated seat 9. A hinge shaft 2a is provided at the end of the swing arm 2 and connected to the articulated seat 9. The swing arm 2 can be rotated to move the head end of the swing arm 2 closer to or further away from the base 1. The power probe 8 is mounted on the head end of the swing arm 2, so that the power probe 8 can be electrically contacted with the top surface of the laser assembly 3 to achieve power, or the power probe 8 can be removed.

[0027] As a preferred embodiment, a spring is provided on the hinge shaft 2a of the swing arm 2. The specific structure of the spring on the rotating shaft is conventional in the mechanical field and is not illustrated in the figure. This spring causes the swing arm 2 to tend to approach the base 1. The spring design not only ensures the stability of the swing arm 2 when it approaches the base 1, but also enhances the contact pressure between the power-on probe 8 and the laser assembly 3, thereby improving reliability during the power-on process.

[0028] To meet the powering requirements of different laser assembly models 3, in this embodiment, the power probe 8 is not directly fixedly connected to the swing arm 2. Specifically, the head end of the swing arm 2 is also equipped with two telescopic rods 10, each with an adjustment hole 2b. The telescopic rods 10 can be adjusted along the adjustment hole 2b and locked with a first lateral adjustment screw 11. The power probe 8 is fixed to the front end of the telescopic rod 10 and is adjusted and locked with a mounting hole and a second adjustment screw 12 on the telescopic rod 10. This design allows the telescopic rod 10 to move forward and backward and rotate, and the power probe 8 can also move up and down, allowing the position of the power probe 8 to be flexibly adjusted according to actual needs.
