The decrease in atmospheric pressure will inevitably have an impact on the electrical and electronic products used in high-altitude areas. About 50% of the Earth's surface area in China is 1000m above sea level, and about 25% is 2000m above sea level. The larger the pressure gradient, the faster the pressure changes, and the greater the chance of component damage. View >>

The temperature range of electronic components is important, as exceeding this range can lead to performance degradation, failure, or damage. Usually, the temperature range for civilian grade use is 0-70 ℃, industrial grade use is -40-85 ℃, and military grade use is -55-128 ℃. Temperature changes have a significant impact on the conductivity, limiting voltage, and current of semiconductors. Modern chips typically contain millions or even tens of millions of transistors and other components, and the accumulation of each small deviation may have a significant impact on the external characteristics of semiconductors. If the temperature is too low, the chip may not be able to open the internal semiconductor switch at the rated working voltage, resulting in abnormal operation. View >>
