specific Embodiment 1

[0032] ①Preparation stage

[0033] Before the test, clean the test bench with absolute ethanol and wipe the probes to check whether the external circuit is in good condition.

[0034] ② start up

[0035] Then turn on the machine to warm up, fix the test bench, adjust the probes, and connect the test lines.

[0036] ③ Place the sample

[0037] Place the sample on the test bench, and rotate the up and down adjustment knob to adjust the probe probe and press the electrode on the surface of the sample, and close the sealing cover.

[0038] ④ Setting conditions

[0039] After closing the sealing cover, turn on the power of the device, open the air inlet valve, and close the air outlet (air extraction) valve. Set the temperature to 40°C (set the heating temperature to 40°C → set the holding time → run), set the humidity to 80% RH (turn on the humidity generator to start generating steam → meet the experimental requirements → the controller sends a signal → the humidity generator...

Abstract

The invention is used for constructing a required test environment and specially relates to an integrated environmental simulation device. The device is composed of seven parts, namely a test chamber,a humidity control module, a temperature control module, a gas mixing module, a pressure control module, a power controller and a test board; the humidity control module and the gas mixing module arearranged on the outer side of the test chamber; the temperature control module and the test board are arranged in the chamber; the pressure control module is arranged on the outer side of the chamber. The device is capable of achieving the aim of a complex environment reliability test for an electronic material and device by regulating and controlling single-parameter conditions or multi-parameter conditions of the electronic material and device. Besides, the device is small and practical and is simple in operation. A real application environment of various electronic materials and devices can be simulated through parameter setting, so that the test and evaluation for electrical properties of the electronic materials and devices can be realized under a simulated condition.

Description

technical field [0001] The invention belongs to the field of testing equipment for electronic materials and devices, and is used to build a required testing environment, in particular to a comprehensive environment simulation equipment. Background technique [0002] At present, the environment in which electronic devices are located is becoming more and more complex. They often work in complex environments with extreme temperature, extreme humidity, air pressure changes and the presence of mixed gases. These external factors will affect the performance of electronic devices. For this reason, it is necessary to evaluate the performance of electronic materials or devices in various external application environments. At present, the temperature, humidity, air pressure, mixed gas and other tests of electronic devices are carried out separately, and the interaction and synergy between various test factors cannot be considered comprehensively, which also makes the final test resul...
