Custom Temperature Humidity And Vibration Combined Environmental Test System For Communication Devices

1. Product Name and Purpose

2. Product Features

Temperature and Humidity Test Chamber

• Wide Temperature and Humidity Range
  • The temperature control in this system can achieve an extensive range, typically from - 40°C to + 85°C. This wide spectrum allows for the simulation of various climate conditions, from the freezing cold of polar regions to the sweltering heat of deserts. The humidity control can maintain relative humidity levels from 10% to 95%. This enables the testing of how communication devices respond to different moisture levels, which is critical for preventing issues like corrosion of electronic components, short - circuits, and degradation of signal quality.
  • The temperature and humidity control is highly precise, with an accuracy of ±0.5°C for temperature and ±3% for humidity. This level of precision ensures that the test conditions closely mimic the actual environmental conditions that communication devices may encounter, providing reliable and consistent test results.
• Rapid Temperature and Humidity Transitions
  • The system is capable of rapid temperature and humidity transitions, essential for simulating sudden changes in the environment. For example, when a communication device is moved from an air - conditioned indoor environment to a hot and humid outdoor area. The system can achieve temperature transition rates of up to 5°C/min and humidity transition rates of up to 5%/min. This allows for the testing of how devices respond to these abrupt changes, helping to identify potential failures due to thermal stress or moisture absorption.
• Uniformity within the Chamber
  • The test chamber is designed to provide excellent temperature and humidity uniformity. The temperature variation within the chamber is typically within ±1°C, and the humidity variation is within ±5% relative humidity. This ensures that all devices being tested are exposed to the same environmental conditions, eliminating any potential biases in the test results.

Vibration Test Section

• Multi - Axis Vibration Capability
  • The vibration test section of the system can generate vibrations in multiple axes, including vertical, horizontal, and lateral directions. Communication devices are often subjected to complex vibration patterns during normal use, such as being dropped, shaken, or carried in a moving vehicle. Testing in multiple axes helps to uncover potential failure modes that may not be detected with single - axis testing.
  • The vibration frequencies can be precisely controlled, ranging from a low 1 Hz to a high 2000 Hz. This wide frequency range allows for the simulation of different types of vibrations, from the low - frequency vibrations during transportation to the high - frequency vibrations caused by sudden impacts. The vibration amplitudes are adjustable, enabling the reproduction of various levels of intensity, from minor vibrations to severe shocks.
• Customizable Vibration Profiles
  • Operators can create custom vibration profiles based on specific test requirements. These profiles can include continuous vibrations, intermittent shocks, or complex vibration sequences that mimic real - world scenarios. For example, a profile can be designed to simulate the vibrations a smartphone might experience during a long - distance journey in a vibrating vehicle, with occasional bumps and jolts.

Customization Options

• Device - Specific Fixtures
  • The system comes with a range of device - specific fixtures that can be customized to securely hold different types of communication devices during testing. These fixtures are designed to ensure proper positioning and orientation of the devices, allowing for accurate and consistent testing. For example, there are fixtures specifically designed for smartphones, tablets, and small - sized wearable communication devices, as well as larger fixtures for base stations and routers.
• Test Sequence Customization
  • Manufacturers can customize the test sequence to meet their specific needs. They can define the order and duration of temperature, humidity, and vibration tests, as well as the specific parameters for each test. This flexibility allows for a more targeted and comprehensive evaluation of communication devices under different environmental stress combinations.

Integrated Control and Monitoring

• User - Friendly Interface
  • The entire test system is controlled through a user - friendly interface that simplifies the operation process. The interface allows operators to easily set and adjust the test parameters for temperature, humidity, and vibration. It provides a clear display of the current test status, including temperature, humidity, vibration frequencies, amplitudes, and elapsed test time.
• Comprehensive Data Acquisition and Analysis
  • Equipped with a comprehensive data acquisition system, the test system records all relevant data during the test. This includes temperature and humidity profiles, vibration measurements, and any observed device failures or performance changes. The data can be stored in a secure database and analyzed using advanced software tools. The system can generate detailed test reports, including graphs, charts, and statistical analysis, to help engineers and researchers understand the test results and make informed decisions.
• Remote Monitoring and Control
  • Many models of this combined test system offer remote monitoring and control capabilities. This feature enables operators to monitor the test progress and adjust the test parameters from a remote location, such as an office or a different facility. It is particularly useful for large - scale testing operations or when immediate access to the testing system is not possible.
