Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, and in particular to an environmental simulation testing mechanism for chip testing. Background Technology

[0002] A chip is an integrated circuit composed of a large number of transistors. Different chips have different integration scales, ranging from hundreds of millions to tens or hundreds of transistors. Environmental simulation testing is an activity conducted to maintain functional reliability under all expected usage, transportation, or storage environments. Chip environmental adaptability testing aims to verify the reliability and stability of chips under different environmental conditions. Traditional chip testing equipment has limited functionality and cannot simultaneously simulate complex environmental conditions, and the test chamber lacks sufficient sealing. To address these issues, we have launched an environmental simulation testing mechanism for chip testing. Summary of the Invention

[0003] This utility model discloses an environmental simulation testing mechanism for chip testing, which aims to solve the technical problems of traditional chip testing equipment having limited functions, being unable to simultaneously simulate complex environmental conditions, and having insufficient sealing of the testing chamber.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An environmental simulation testing mechanism for chip testing includes a base, a platform connected to the top of the base via a vibration assembly, an environmental detection box connected to the top of the platform via a clamping assembly, a cover plate connected to the top of the environmental detection box via an auxiliary assembly, a detection chamber formed inside the environmental detection box near the top, a placement plate fixedly installed inside the detection chamber near the bottom, a first guide ring and a second guide ring fixedly installed alternately on the bottom wall inside the detection chamber, symmetrically formed fixing slots inside the environmental detection box and below the detection chamber, a cooler and a heater respectively fixedly installed inside the two fixing slots, the bottom ends of the first guide ring and the second guide ring respectively connected to the cooler and the heater via connecting rods, a temperature and humidity sensor fixedly installed inside the detection chamber near the top, a connecting pipe fixedly installed through the cover plate, the bottom end of the connecting pipe extending into the detection chamber and fixedly installed with an atomizing nozzle.

[0006] In use, auxiliary components facilitate fixing the cover plate to the top of the environmental testing box, vibration components facilitate collision detection of the chip inside the testing chamber, and clamping components facilitate fixing the environmental testing box to the top of the platform. The chip is placed on top of the placement plate through the environmental testing box. Coolers and heaters facilitate cyclic startup, and corresponding connecting rods and guide rings one and two heat and cold cycles are applied to the placement plate, thereby subjecting the chip to hot and cold cycles. Furthermore, the other end of the connecting pipe connects to an external water tank, facilitating the spraying of water mist into the testing chamber through the atomizing nozzle for humidity testing. This integrated testing solution solves the technical problems of traditional chip testing equipment, such as limited functionality, inability to simultaneously simulate complex environmental conditions, and insufficient sealing of the testing chamber.

[0007] In a preferred embodiment, the vibration assembly includes fixed blocks. Fixed blocks are symmetrically fixedly installed at the top center of the base. A rotating block is fixedly installed at the bottom of the platform, located between the two fixed blocks. The rotating block is connected to the two fixed blocks via a rotating shaft. An installation groove is provided on one side of the top of the base. A first electric telescopic rod is connected to the top of the installation groove via a rotating frame. The output end of the first electric telescopic rod is connected to the rotating frame and the bottom of the platform.

[0008] By setting up a vibration component, the up-and-down movement of the output end of the No. 1 electric telescopic rod causes the platform to sway left and right around the rotating shaft, which in turn causes the chip to sway and collide inside the detection chamber, which is beneficial for collision detection of the chip.

[0009] In a preferred embodiment, the clamping assembly includes a movable slot located at the center of the top of the platform. A motor is connected to one side of the platform via a mounting bracket. A bidirectional lead screw is rotatably connected inside the movable slot. One end of the bidirectional lead screw extends to the outside of the platform and is fixedly connected to the motor. A movable plate is symmetrically threaded onto the outside of the bidirectional lead screw and inside the movable slot. Support plates are symmetrically fixedly installed on both sides of the bottom of the environmental detection box. Each support plate has a insertion slot on the side near the movable plate. An insertion plate is fixedly installed on the side of the movable plate that is close to the corresponding insertion slot. The insertion plate extends into the corresponding insertion slot.

[0010] By setting up a clamping assembly, the environmental monitoring box is placed on the top of the platform. The motor drives the bidirectional lead screw to rotate, which in turn moves the two moving plates toward the corresponding support plates, so that the plug-in plate extends into the corresponding plug-in slot, making it easy to fix the environmental monitoring box on the top of the platform and facilitating the use of the vibration assembly.

[0011] In a preferred embodiment, the auxiliary component includes a mounting plate. Mounting plates are fixedly mounted on the bottom periphery of the environmental monitoring box. A second electric telescopic rod is fixedly mounted on the top of each mounting plate. Connecting plates are fixedly mounted on the periphery of the cover plate and near the corresponding second electric telescopic rod. The output end of the second electric telescopic rod is fixedly connected to the corresponding connecting plate. A sliding rod is fixedly mounted on the side of the cover plate near the environmental monitoring box. A sliding groove is formed on the side of the environmental monitoring box near the sliding rod. The sliding rod extends into the sliding groove and is slidably connected to it. A sealing element is fixedly mounted on the side of the cover plate near the environmental monitoring box. A sealing groove is formed on the side of the environmental monitoring box near the sealing element. The sealing element extends into the sealing groove.

[0012] By setting auxiliary components, the No. 2 electric telescopic rod can easily drive the connecting plate and then the cover plate to move up and down, thereby opening or sealing the environmental monitoring box. The sliding rod and sliding groove can enhance the stability of the cover plate's up and down movement, and the sealing groove and sealing element can enhance the sealing performance of the connection between the environmental monitoring box and the cover plate.

[0013] In a preferred embodiment, a limiting plate is fixedly installed on the bottom of the platform away from the first electric telescopic rod, and a limiting groove is formed inside the base and on the side close to the limiting plate. The bottom end of the limiting plate extends into the limiting groove and a limiting block is fixedly installed thereon. Both the limiting plate and the limiting block are slidably connected to the limiting groove.

[0014] Setting limit slots, limit plates, and limit blocks helps to enhance the stability of the platform when it sways left and right.

[0015] In a preferred embodiment, the environmental monitoring box has a connecting groove on its back side and near both fixing slots. A cooling fan is fixedly installed inside each connecting groove by bolts. A heat dissipation groove is provided through the bottom of each fixing slot.

[0016] The installation of cooling fans and heat dissipation slots helps to dissipate the heat generated by the coolers and heaters inside the two fixed slots.

[0017] In a preferred embodiment, a control panel is fixedly mounted on the surface of the base. The first electric telescopic rod, the motor, the second electric telescopic rod, the cooler, the heater, the cooling fan, and the temperature and humidity sensor are all electrically connected to the control panel. An observation window is provided in the middle of the top of the cover plate.

[0018] The control panel makes it easier to control the No. 1 electric telescopic pole, the motor, the No. 2 electric telescopic pole, the cooler, the heater, the cooling fan, and the temperature and humidity sensor. The observation window makes it easier to observe the chip inside the detection chamber.

[0019] The environmental simulation testing apparatus for chip testing provided by this utility model has the following advantages:

[0020] Firstly, during use, auxiliary components facilitate fixing the cover plate to the top of the environmental testing box, vibration components facilitate collision detection of the chip inside the testing chamber, and clamping components facilitate fixing the environmental testing box to the top of the platform. The chip is placed on top of the placement plate through the environmental testing box, and the cooler and heater facilitate cyclic start-up. The placement plate is heated or cooled through corresponding connecting rods and guide rings one and two, thereby subjecting the chip to hot and cold cycles. Furthermore, the other end of the connecting pipe is connected to an external water tank, facilitating the spraying of water mist into the testing chamber through the atomizing nozzle, which is convenient for humidity testing inside the testing chamber. This integrated testing solves the technical problems of traditional chip testing equipment having limited functions, being unable to simultaneously simulate complex environmental conditions, and having insufficient sealing of the testing chamber.
