• Precision Environmental Control Systems
  • Temperature Control: Capable of maintaining a temperature range from -50°C to +150°C, with an astounding accuracy of ±0.3°C. This is achieved through a combination of advanced compressor-based refrigeration and high-power resistive heating elements. The control system utilizes a sophisticated PID (Proportional-Integral-Derivative) algorithm, in conjunction with multiple platinum resistance temperature detectors (RTDs) strategically positioned throughout the chamber. This setup ensures not only precise temperature control but also minimal temperature gradients, allowing for uniform aging of all samples. The user-friendly touchscreen interface enables the programming of complex temperature profiles, such as simulating the thermal cycling that occurs during power-on and power-off cycles of an electronic device, or replicating the temperature changes in a harsh industrial environment.
  • Humidity Control: The humidity control system can achieve relative humidity levels ranging from 10% to 95% RH, with an accuracy of ±2% RH. It employs a hybrid approach, incorporating ultrasonic humidifiers for moisture addition and desiccant dehumidifiers for moisture removal. The chamber is equipped with high-precision capacitive humidity sensors that continuously monitor the internal humidity, and the control system makes instantaneous adjustments to maintain the desired levels. This is crucial for testing the effects of moisture on electronic components, such as the corrosion of metal contacts, the swelling of plastic housings, or the degradation of electrical insulation. The system can be programmed to create dynamic humidity profiles, including rapid changes and long-term stability tests, mimicking real-world scenarios like the transition from a dry indoor environment to a humid outdoor one.

The vibration table can produce a wide range of frequencies, from 10 Hz to 2000 Hz, with adjustable amplitudes from 0.5 mm to 50 mm. The shock generator can deliver precise shock pulses with magnitudes ranging from 20 g to 1000 g (where g is the acceleration due to gravity) and durations from a few milliseconds to several seconds. These capabilities are essential for testing the resilience of electronic components and assemblies to the vibrations and shocks experienced during transportation, operation in vibrating machinery, or accidental drops. The control system allows for the programming of custom vibration and shock sequences, including random vibration patterns and multi-axis shock simulations.
  • Electrical Stress Application: The chamber also offers the ability to apply electrical stress to the tested electronics. It can provide adjustable voltage and current levels, enabling the simulation of overvoltage, undervoltage, power surges, and electrostatic discharge events. The electrical stress can be applied continuously or in a pulsed manner, and the control system monitors the electrical parameters in real-time, ensuring compliance with the specified stress levels. This is vital for assessing the robustness of electronic components, such as capacitors, transistors, and integrated circuits, against electrical abnormalities that may occur during their operational life.

The ramp rate can be adjusted, typically ranging from 2°C per minute to 20°C per minute, allowing for the simulation of different thermal profiles, such as the rapid heating and cooling that occurs during a device's startup and shutdown sequences or the slower temperature changes in a long-term storage environment.
• Humidity Cycling Rate: The humidity can be cycled within 15 minutes to 2 hours, enabling the simulation of rapid changes in moisture conditions. For example, it can change the humidity level from 20% RH to 90% RH and back, replicating the transitions that may occur when an electronic device is moved between different environments, such as from a dry office to a humid outdoor location or vice versa.
• Vibration and Shock Parameters: The vibration system can generate frequencies from 5 Hz to 1500 Hz, with amplitudes adjustable from 1 mm to 20 mm. The shock generator can deliver shock pulses with magnitudes ranging from 30 g to 500 g and durations from 5 milliseconds to 100 milliseconds. These parameters are carefully selected to cover a wide range of real-world mechanical stress scenarios that electronics may encounter.
