Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging and testing, in particular to a high-temperature resistant packaging and testing device for semiconductor chips. Background Art
[0002] Semiconductor chip packaging and testing is an essential process step for chips to become qualified products. With the rapid advancement of the semiconductor chip industry, there are many cases where trial packaging and testing of new product performance are required, and the speed must be very high. Existing semiconductor chip high-temperature resistant packaging and testing equipment is too high when performing heat testing on the chip. If the tester directly picks up the chip, he will be burned. After the test, the tester needs to wait for the internal temperature of the device to drop before removing the chip, which reduces work efficiency and is inconvenient to use.
[0003] According to patent publication number CN211653067U, a protective semiconductor chip high-temperature resistant packaging test device is disclosed. When the test is completed, the cooling pump is started to cool the coolant in the cooling box, and then inputs it into the heat exchange tube through the second connecting pipe to exchange heat with the high temperature inside the heating box. The coolant after heat exchange returns to the cooling box through the first connecting pipe, and then enters the heat exchange tube for heat exchange after being cooled by the cooling pump, cooling the inside of the heating box. The temperature inside the heating box is effectively and rapidly cooled, so that the tester can quickly remove the chip.
[0004] However, the above patent lowers the temperature of the heating box in order to take out the chip. When the chip needs to be tested later, the temperature inside the heating box still needs to be reheated to the required temperature. The above patent has high energy consumption and cannot enable the test device to perform continuous testing, and the test efficiency is low. For this reason, we propose a semiconductor chip high-temperature resistant packaging test device. Utility Model Content
[0005] The main purpose of the utility model is to provide a semiconductor chip high temperature resistant packaging and testing device, which can effectively solve the problems in the background technology.

[0008] In order to limit the mounting block, as a semiconductor chip high temperature resistant packaging test device of the present invention, a limiting groove is provided on the upper surface of the test table, and the mounting block is slidably connected to the interior of the limiting groove.
[0009] In order to make the test box more stable, as a semiconductor chip high temperature resistant packaging test device of the present invention, the upper surface of the test table is fixedly connected to the test box by bolts, and a heating chamber is opened inside the test box.
[0010] In order to heat the test box, as a semiconductor chip high-temperature resistant packaging test device of the present invention, a heating wire is installed inside the heating chamber, and the heating wire is electrically connected to the temperature controller through a wire, and the temperature controller is fixedly installed on the upper surface of the test bench.
[0011] In order to make the servo motor more securely installed, as a semiconductor chip high-temperature resistant packaging test device of the present invention, a motor bracket is fixedly connected to one side of the test bench, and a servo motor is fixedly connected to the upper surface of the motor bracket.
[0012] In order to facilitate opening the door, as a semiconductor chip high-temperature resistant packaging test device of the present invention, the front of the test bench is hinged with a door through a hinge, and a handle is fixedly connected to one side of the front of the door.
[0013] In order to make the device more stable, as a semiconductor chip high-temperature resistant packaging test device of the present invention, the four corners of the lower surface of the test table are fixedly connected with support legs, and the number of the support legs is four.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The semiconductor chip high-temperature resistant packaging test device is arranged by coordinating a test table, a threaded rod, a mounting block, a placement rack, a clamping block, a placement frame and a test box. When it is needed, a staff member can first place the test chip inside the placement frame, and then the staff member can start the servo motor, which drives the threaded rod to move, so that the first group of placement frames with test chips enter the test box. After the test is completed, the servo motor is started again, and the threaded rod controls the placement rack to move during rotation, so that the first group of test chips can be removed from the test box, and the second group of chips to be tested enters the test box for temperature testing. After the first group of test chips are pushed out of the test box, they cool down faster, making it easier for the staff member to remove the chips, and the test box does not need to be cooled down, so other chips can be tested. This not only saves energy, but also increases the utilization rate of the test box, and can continuously perform chip temperature measurement, thereby improving test efficiency.
