The integrated circuit thermal shock test box is a widely used piece of equipment across various industries, including scientific research, aerospace, defense, electrical engineering, electronics, toys, plastics, hardware, batteries, mobile phones, optoelectronics, and LEDs. Our company specializes in providing high-quality environmental testing equipment that meets international standards such as GB, GJB, IEC, MIL, and DIN. We serve a wide range of enterprises, from scientific institutions to automotive and communication companies, offering reliable solutions backed by strong technical expertise and financial support.
Understanding the temperature ratings and deviations of an integrated circuit thermal shock test box is crucial for customers when selecting the right testing equipment. Once they know the temperature levels the chamber can reach, they can make an informed decision on which model best suits their testing needs.
These test boxes operate using a blast principle to ensure even temperature distribution within the chamber, allowing for adjustable airflow in the working area. However, since they are not designed for wind resistance testing, the standard wind speed is typically set at 3.7 m/s.
In terms of temperature specifications, the high-temperature rating of the test box includes ranges such as 30°C, 40°C, 55°C, 70°C, 85°C, 100°C, 125°C, 155°C, and 180°C, with a maximum deviation of ±2°C. For low-temperature testing, the available temperatures are 0°C, -10°C, -25°C, -40°C, -60°C, -70°C, and -80°C, with a deviation of no more than ±3°C.
The temperature uniformity inside the chamber should not exceed 2.0°C at both high and low temperatures, while the temperature fluctuation is limited to ±0.5°C at high temperatures and ±1.0°C at low temperatures.
Additionally, the temperature difference between the inner walls of the chamber and the working space must be within 3% at high temperatures and no more than 8% at low temperatures.
The heating and cooling rate under full load conditions is also an important factor. The temperature rise rate per 5 minutes is typically no more than 1°C/min, 1±0.2°C/min, 3±0.6°C/min, or 5±1°C/min, depending on the model.
Humidity control is not required during high-temperature testing. In such conditions, the absolute humidity in the working space should not exceed 20 g/m³ (equivalent to 35°C with 50% relative humidity).
