1.Low Air Pressure Environment Due to the gravity of the earth, the air has a certain weight to form atmospheric pressure. The atmospheric pressure at a certain height is the heaviest of the entire air column on the unit area perpendicular to the ground above the point. With the increase of height, the air …
1.Overview High and Low Temperature Humidity Test Chamber is a kind of equipment that can be used for the reliability test of lithium batteries, small electronic products, electronic components and materials, or for the climate test of other products. The temperature adjustment range of high and low temperature damp heat laboratory is generally +60 ℃ …
High and low temperature damp heat test chamber is the most sold product in the test equipment at present. In the market, the temperature and humidity of this kind of test chamber are constant. Most of them adopt thermal control, that is, the heat of the heater offsets the cold volume of the evaporator to …
The reliability of electronic products is affected by many factors. In addition to human operation, the environment in which the products are located is also an important reason for their work failure. Among them, temperature, humidity and vibration are the three main environmental factors that have the greatest impact on the product equipment. This paper …
3.3 Test Requirements and Methods (1) During the temperature test, the temperature change speed between each temperature step shall not exceed 20 ℃ /h. During the test, the relevant test can be carried out only after the tested instrument reaches the temperature stable state as far as possible. (2) During the high and low temperature …
At present, electronic instruments are used in military, civil and high-tech fields. However, the low temperature environment exists in most of its service environments. Therefore, the adaptability of electronic instruments at low temperature is directly related to their quality. Based on this, this paper analyzes the low temperature environmental effects and low temperature test technology …
