Description

technical field [0001] The invention belongs to the field of quality inspection, and relates to a product reliability analysis device, in particular to a universal conversion anti-frost system connector and a heat flow meter at the gas outlet of a heat flow meter. Background technique [0002] In order to ensure the reliability and service life of semiconductor components, high-speed high-low temperature impact tests are required after semiconductor components are produced. The commonly used test equipment is high-low temperature test chambers and thermal shock test chambers. When conducting high and low temperature tests, the samples are placed in a closed test box, heated by an electric heater, or refrigerated by a refrigeration compressor unit to test the performance of the sample. When performing a thermal shock test, it is necessary to switch the sample back and forth between a high temperature environment and a low temperature environment to test the performance of t...

Problems solved by technology

[0003] When the output airflow of the thermal shock testing machine is output to the closed experimental environment through the output pipeline, the external environment of the output pipeline transfers heat to the output airflow, resulting in low temperature stability of the output airflow and poor temperature control accuracy; and Since the air flow in the output pipe is lower than the environment outside the output pipe, frosting is prone to occur on the outer wall of the output pipe, which further reduces the temperature stability of the output air flow, so it is necessary to find a way and method to improve
