Introduction to temperature and deviation of integrated circuit thermal shock test box

The integrated circuit thermal shock test box is widely used in various industries such as scientific research, aviation, military, electrician, electronics, toys, plastics, hardware, batteries, mobile phones, optoelectronics, LED, and other industrial parts. The company provides excellent environmental testing equipment in accordance with GB, GJB, IEC, MIL, DIN and other standards for scientific research, electrician, electronics, military, aviation, communications, automobiles, notebook computers and other enterprises with excellent talents, technology and funds. .

Introduction to temperature and deviation of integrated circuit thermal shock test box

How to confirm the temperature grade and deviation of the integrated circuit thermal shock test box has always been one of the problems that customers have to deal with, because after knowing the temperature level of the high and low temperature test chamber, it can make the final test which type of test equipment is purchased. Judgment.

The integrated circuit thermal shock test box uses the blast principle to ensure the uniformity inside the box, so the wind speed in the working space should be adjustable. However, the equipment is mainly not used for windproof test, so only the standard value is used: 3.7m/s.

The high temperature temperature rating of the integrated circuit thermal shock test box is: 30, 40, 55, 70, 85, 100, 125, 155, 180 ° C. (The high temperature temperature deviation is not more than ± 2 ° C)

The low temperature temperature rating of the integrated circuit thermal shock test box is: 0, -10, -25, -40, -60, -70 °C, -80 °C. (The temperature deviation of low temperature is not more than ±3 °C.)

The temperature uniformity of the test chamber at high temperature and low temperature should be no more than 2.0 °C.

The temperature fluctuation of the test chamber is not more than ±0.5 °C at high temperature and not more than ±1.0 °C at low temperature.

The difference between the temperature of the inner wall of the studio and the temperature of the working space

The difference between the temperature of the working chamber wall and the working space temperature shall not be greater than 3% of the temperature of the test chamber at high temperatures and not more than 8% at low temperatures.

Test chamber heating and cooling rate

Under full load conditions, the uniform temperature rise rate per 5 min is: no more than 1 ° C / min, 1 ± 0.2 ° C / min, 3 ± 0.6 ° C / min, 5 ± 1 ° C / min.

Do not use the humidity: Under high temperature conditions, the absolute humidity in the working space should be no more than 20gm3 (corresponding to 35°C, the relative humidity is 50%).
