High and low temperature impact airflow instrument is a kind of high and low temperature airflow cycle impact equipment used for the cold and hot test of electronic components/modules. The insulation and heat insulation hood (or other heat insulation hood) covers the measured object (IC) to isolate it from the surrounding environment, prevent ambient air from entering, and create a closed, repeatable heat transfer environment. The heat insulation hood is usually placed on the test fixture, and the airflow impact is centered on the sample to be tested. The thermal insulation hood is very important for the test. Any deviation will affect the test results.

In the actual test, different sizes of thermal insulation hoods can test different sizes of chips, and different sizes of thermal insulation hoods (or other thermal insulation hoods) can be selected according to the size of the chips to be tested and other specific test requirements. If there are many components on a PCB, but only one IC needs to be impacted at high and low temperatures independently without affecting other components around, the adaptability of the thermal insulation hood to the chip will be highlighted.

The size of thermal insulation hood (or other thermal insulation hood) ranges from 2.5 "to 7". Conventional products can be adapted to various product sizes of customers. Chengdu Intercooling Low Temperature Co., Ltd. is always available in stock, and the thermal insulation hood can be customized according to the customer's on-site product size.

According to the test requirements of a customer for integrated chips, Chengdu Intercooling Cryogenics Co., Ltd. customized according to the customer's on-site product size, and successfully made a square steel cover with clips, with quick clips around it. Compared with the general thermal insulation glass wind shield, it is not easy to damage, has a longer service life, and further reduces the micro leakage of gas. The cold and hot shock testing machine can provide effective and uniform purging air flow to the surface of the components required by the customer vertically through the square steel cover with clamps. The 4~18 SCFM (1.9 L/s~8.5 L/s) wind speed can be selected by the customer according to different requirements; And the above operations will not affect other non test components Ensure one-way analysis of customers. The square steel hood with clamps is placed on the laboratory desktop, and one side is connected with a muffler exhaust pipe to reduce noise and exhaust gas.
