With the development of the semiconductor component industry, the performance testing of various electronic components in various complex environments has become prominent. High and low temperature testing machines are specialized equipment for simulating and testing the performance of electronic components in various environments.

In terms of reliability testing for automotive grade chips, Shanghai Putaike High and Low Temperature Testing Machine has unique advantages that are different from traditional high and low temperature impact testing chambers: fast temperature change rate, fast temperature rise/fall of 18 ℃ per second, real-time monitoring of the actual temperature of the tested component, and the temperature of the impact airflow can be adjusted at any time. It can perform high and low temperature impact on a single IC among many components on the PCB circuit board separately, without affecting other peripheral components

It mainly consists of refrigeration system, circulation system, control system, box, etc. The refrigeration system adopts steam compression refrigeration, and the compressor and main refrigeration components are all from internationally renowned brands. The circulation system consists of a circulation pump, electric heating pipes, expansion vessels, exhaust valves, one-way valves, thermal resistors, pipelines, etc. The control system adopts PID control technology, high-definition touch screen display, and is equipped with multiple protection functions to ensure the safe operation of the equipment. By cooling and heating the unit itself, the heat carrying fluid is transported to the outside world to meet the requirements of the process conditions. Suitable for external applications that require rapid heating and cooling, for temperature control and material testing of glass reactors, metal reactors, bioreactors, etc. It is particularly suitable for controlling processes that require heat and release during the reaction process.

The refrigeration system adopts a single compressor refrigeration and a two-stage cascade refrigeration method. And it is equipped with multiple protection functions to ensure the safe operation of the equipment. Through the refrigeration of the unit itself, the liquid low-temperature refrigerant is sent to the end evaporator for cooling, creating a low-temperature environment that meets the requirements of the process conditions.
