Description

Technical Field

[0001] The present invention relates to the technical field of chip detection, and particularly relates to a honeycomb chip aging detection platform. Background Art

[0002] After the chips are manufactured, they need to undergo strict aging tests. With the breakthrough of the performance of optical chips and the rapid increase in the market's demand for the number of chips, the operation efficiency of existing aging detection equipment can no longer meet the requirements.

[0003] Existing aging detection platforms adopt a drawer structure. The drawer is removed from the detection box for loading. The chips are fixed on the aging fixtures inside the drawer, and then the drawer is inserted into the detection box and the chips are powered on for detection. Each drawer can only be set with a single group of chips. The number of drawers that can be set in the entire detection box is very limited, and the utilization rate of the internal space is low, resulting in low chip detection production capacity. Moreover, the detection mechanism is complex, leading to great transformation pressure during the process of expanding production. If more equipment is directly invested to expand production capacity, a series of tasks such as increasing the area of the dust-free workshop will also be faced, and the cost pressure is too high.

[0004] Therefore, it is very necessary to develop an aging detection platform that can effectively improve the utilization rate of the space in the detection box, improve the detection efficiency, and simplify the detection mechanism. Summary of the Invention

[0005] The purpose of the present invention is to provide a honeycomb chip aging detection platform to solve the technical problems existing in the prior art, that is, the aging detection platform adopts a drawer structure, the number of drawers that can be set in the detection box is very limited, the utilization rate of the internal space is low, resulting in low chip detection production capacity, and the detection mechanism is complex, leading to great transformation pressure during the process of expanding production.

[0006] To achieve the above purpose, the technical solution of the present invention is:

[0007] A honeycomb chip aging detection platform includes a plurality of detection modules. The detection modules are in a cylindrical structure, and the cross-section of the detection module is a regular n-sided polygon, where n is a natural number greater than or equal to 3. The sides of the plurality of detection modules are connected to each other in a fitting manner to form a honeycomb structure. Each detection module is provided with n multi-functional PCB boards and n aging fixtures that are electrically connected to the multi-functional PCB boards one by one. A plurality of detection chips are placed on the aging fixtures.

[0008] By adopting the above solution, a plurality of detection modules are connected to each other in a fitting manner to form a honeycomb structure. Each detection module can be provided with multiple aging fixtures and multi-functional PCB boards. The honeycomb structure can make full use of the equipment space, thereby greatly improving the aging detection efficiency. The detection modules can be freely combined according to the actual production capacity requirements. The modular design is convenient for customers to increase production capacity and expand the equipment capacity.

[0009] Based on the above technical solutions, the present invention can be further improved as follows:

[0010] Further, the detection module includes:

[0011] A cylinder with open ends at both ends. The cylinder is composed of n side plates connected end to end, and each inner side of the side plates is provided with one of the multifunctional PCB boards;

[0012] A cover plate, detachably fixed at one open end of the cylinder. The inner side of the cover plate is provided with n aging fixtures corresponding to the n multifunctional PCB boards one by one. When the cover plate covers the opening of the cylinder, the aging fixtures are electrically connected to the multifunctional PCB boards;

[0013] A heat dissipation unit, arranged at the other open end of the cylinder.

[0014] By adopting the above scheme, the cover plate can be disassembled for loading and unloading the chips. After the loading is completed, the cover plate is covered on the cylinder. At this time, the multifunctional PCB board and the aging fixture are electrically connected. By controlling the power supply of the multifunctional PCB board, the test can be started. The heat dissipation unit is arranged at the inner end face of the cylinder, which can realize the heat dissipation inside the cylinder to control the aging detection temperature.

[0015] Further, a partition unit is arranged inside the cylinder. The partition unit divides the interior of the cylinder into independent detection spaces corresponding to the n multifunctional PCB boards one by one.

[0016] Further, the partition unit includes a cylinder body located at the center of the cylinder. The cylinder body extends along the axial direction of the cylinder, and there are n partitions between the outer circumferential surface of the cylinder body and the inner corners of the cylinder. The end of each partition close to the cover plate is also provided with an upper sealing plate. The upper sealing plate, the partition and the side plate cooperate to form n detection spaces. Each detection space is provided with one of the multifunctional PCB boards, and the probes of the multifunctional PCB board pass through the upper sealing plate and are connected to the aging fixture.

[0017] By adopting the above scheme, a cylinder body and a partition structure are arranged inside the cylinder to form multiple detection spaces, and each multifunctional PCB board is made independent to avoid mutual influence.

[0018] Further, the partition is provided with notches for fixing the multifunctional PCB board. The multifunctional PCB board is inserted into the notches of a pair of adjacent partitions for fixing, and there is a gap between the multifunctional PCB board and the corresponding side plate to form a heat dissipation channel.

[0019] By adopting the above solution, the multi-functional PCB board is inserted and fixed in the card slot of the partition board, and at the same time, the card slot between the multi-functional PCB board and the side board can form a heat dissipation channel exclusive to the aging jig.

[0020] Further, an opening matching the cylinder body is formed on the upper sealing plate. The center of the inner side surface of the cover plate is fixed with a push rod arranged along the axial direction of the cylinder body. A piston for sealing cooperation with the cylinder body is arranged at the end of the push rod. A gas hole is formed in the center of the cover plate, and a gas joint located on the outer side surface of the cover plate is installed at the gas hole. A gas channel communicating with the gas joint is formed inside the push rod and inside the piston. A lower sealing plate for sealing the cylinder body is arranged at one end of the cylinder body far away from the cover plate.

[0021] By adopting the above solution, the piston of the cover plate is inserted into the cylinder body. Therefore, a sealed space is formed between the piston and the lower sealing plate. By injecting or extracting air through the gas joint, the negative pressure and positive pressure of the sealed space can be realized. In the negative pressure state, the piston is pressed towards the lower sealing plate side, so as to ensure the stable connection between the aging jig on the inner side surface of the cover plate and the multi-functional PCB board. In the positive pressure state, the piston is pushed out under the action of pressure, so as to realize the separation of the cover plate for loading and unloading operations.

[0022] Further, the cylinder body, the partition board and the column body are integrally formed.

[0023] Further, the heat dissipation unit is an exhaust fan.

[0024] Further, the adjacent detection modules are fixed by a snap structure.

[0025] Further, n is an even number. The snap structure includes a card slot arranged on the outer surface of half of the side plates of the detection module and a snap arranged on the outer surface of the other half of the side plates of the detection module. The card slot includes a pair of first brackets with an L-shaped cross section. The pair of first brackets are symmetrically arranged along the axial direction of the column body on the side plate surface. One end of the first bracket is fixed to the side plate, and the opening of the first bracket faces inwards. The snap includes a pair of second brackets with an L-shaped cross section. The pair of second brackets are symmetrically arranged along the axial direction of the column body on the side plate surface. One end face of the second bracket is fixed to the side plate, and the opening of the second bracket faces outwards. The first bracket and the second bracket cooperate to fix the adjacent detection modules.

[0026] Further, the cross section of the detection module is a regular hexagon.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. The aging detection platform of the present invention adopts a honeycomb structure formed by fitting several detection modules one by one. A plurality of aging fixtures and multi-functional PCB boards are arranged in each detection module. The honeycomb structure can greatly improve the equipment space utilization rate and the aging detection efficiency. The detection modules are modularly arranged and can be freely combined according to the actual production capacity requirements, which is convenient for customers to increase production capacity and expand the equipment capacity.

[0029] 2. The detection module of the present invention adopts a cylindrical structure. The multi-functional PCB board is arranged on the inner surface of the side plate of the cylinder, and the aging fixture is arranged on the cover plate of the cylinder. When the cover plate is closed, the aging fixture is automatically electrically connected to the multi-functional PCB board, which greatly simplifies the structure of the aging detection equipment and effectively reduces the cost.

[0030] 3. The present invention uses a gas joint to control the tightening and detachment of the cover plate. The piston of the cover plate is inserted into the cylinder inside the column body, and a sealed space is formed between the piston and the lower sealing plate. By injecting or extracting air through the gas joint, the negative pressure and positive pressure of the sealed space can be realized. In the negative pressure state, the piston is pressed against the lower sealing plate side, so as to ensure the stable connection between the aging fixture on the inner side of the cover plate and the multi-functional PCB board. In the positive pressure state, the piston is pushed out under the action of pressure, so as to realize the detachment of the cover plate for loading and unloading operations. The operation is fast and the work is stable, avoiding the poor contact phenomenon during the detection state. BRIEF DESCRIPTION OF THE DRAWINGS

The heat dissipation unit is arranged on the inner end surface of the cylinder 4, which can realize the heat dissipation inside the cylinder 4 to control the aging detection temperature.

[0068] A partition 7 unit is arranged inside the cylinder 4. The partition 7 unit divides the inside of the cylinder 4 into independent detection spaces corresponding to the six multi-functional PCB boards 2 one by one.
