Radio frequency chip RF chip mainly provides the transmission and reception of radio electromagnetic wave signals for mobile terminal devices such as mobile phones. It is a core module necessary for cellular network connection, Wi-Fi, Bluetooth, GPS and other wireless communication functions. The global radio frequency market is at a high speed In the era of development, chip and system manufacturers need corresponding test systems to ensure RF chip performance and compliance. Recently, a domestic RF power amplifier manufacturing company purchased the American ThermoStream ATS-710 high and low temperature shock tester through the recommendation of The testing machine provides the RF chip with a fast and accurate external temperature environment of -80 to +225 °C to meet the performance requirements of the test chip.
America's inTEST heat flow meter provides high and low temperature testing solutions for RF chips
inTEST ThermoStream heat flow meter is a special instrument that provides low or high temperature environment for radio frequency chips for reliability testing. It is widely used in chip testing because it can rapidly the temperature in a short time, and can simulate and observe the behavior of chips in harsh environments. Whether the performance can be maintained at a normal level. Generally, the stability of the frequency of the chip in the transmit mode is tested in the range of -40 °C to 80 °C. During the working process of the test system, the system will pass a specific test according to the set temperature. The calculation result is obtained and the heater is controlled to achieve the purpose of adjusting the temperature.
inTEST ATS-710 Features
Temperature range: -80 to +225 °C
Temperature rate: -55 to +125°C about 10 s;
+125 to -55°C approx. 10 s
Temperature display accuracy: ±1℃ (Calibrated by NIST, National Institute of Standards and Technology)
Automatic heating and cooling: The freezer is specially designed, the refrigerant does not contain Freon, is safe, non-toxic, non-flammable, and effectively protects the environment;
No need for liquid nitrogen LN2 or liquid carbon dioxide LCO2
Cooling to prevent frost: Dry air flow circulates to purge the test surface to prevent moisture condensation (gas flow rate 0.5 to 3 scfm)
Automatic standby: In idle or heating mode, automatically reduce energy consumption Heating defrost:
Quickly remove accumulated water vapor inside the freezer
Compared with traditional high and low temperature experimental chambers and temperature and humidity test chambers, the main advantages of inTEST ThermoStream heat flow meter are:
1. Faster temperature rate
2. Temperature control accuracy: ±1℃
3. Real-time monitoring of the actual temperature of the component under test, and the impact airflow temperature can be adjusted at any time
4. A single IC (module) among the many components on the PCB circuit board can be subjected to high and low temperature shocks independently without affecting other surrounding components.
5. Perform temperature cycling/shock on the IC on the load board of the test machine platform; traditional high and low temperature chambers cannot be used for this type of testing.
6. Provide accurate and fast ambient temperature for the entire integrated circuit board.
