Constant Climatic Test Chamber For Temperature Humdity Test Of Circuit Board

1. Product Name and Purpose

2. Product Features

Precise Climatic Control

• Wide Temperature Range
  • The chamber is capable of achieving a broad temperature range, typically from - 55°C to + 150°C. This wide range is essential as circuit boards can be exposed to extremely cold temperatures in applications such as aerospace or military equipment operating in polar regions, or high heat in industrial environments with poor ventilation or in high - power electronic devices. The temperature control is highly precise, with an accuracy of ±0.1°C. This precision allows for accurate replication of specific temperature conditions that circuit boards may experience in real - world scenarios, ensuring reliable test results.
• Accurate Humidity Regulation
  • Humidity levels within the chamber can be precisely regulated from 10% to 98% relative humidity. High humidity can cause corrosion, moisture absorption, and electrical leakage in circuit boards, while low humidity can lead to electrostatic discharge issues. The humidity control accuracy of ±2% relative humidity ensures that the test environment closely mimics the real - world humidity conditions that circuit boards may encounter, enabling manufacturers to evaluate the boards' performance under different moisture levels.

Stable and Uniform Environment

• Uniform Climatic Distribution
  • The interior of the constant climatic test chamber is designed to provide a uniform distribution of temperature and humidity throughout the test volume. Advanced air circulation systems and strategically placed sensors work in tandem to ensure that the temperature variation within the chamber is typically within ±0.5°C, and the humidity variation is within ±3% relative humidity. This uniformity is crucial for accurate testing, as it ensures that all parts of the circuit board are exposed to the same environmental conditions, eliminating any potential biases in the test results.
• Long - Term Stability
  • The chamber is capable of maintaining stable climatic conditions over extended periods. This is essential for conducting long - term reliability tests on circuit boards, which may require continuous exposure to specific temperature and humidity conditions for hundreds or even thousands of hours. The chamber's stability ensures that the test conditions remain constant throughout the test, providing consistent and comparable results that are essential for making informed decisions about product design and quality improvement.

Multiple Test Modes and Customization

• Programmable Test Profiles
  • Operators have the flexibility to create programmable test profiles that simulate the complex and variable environmental conditions that circuit boards encounter in real - world applications. These profiles can include cyclic changes in temperature and humidity to mimic seasonal variations, sudden changes to simulate extreme weather events, or custom - tailored profiles based on the specific requirements of a particular circuit board or application. For example, a test profile can be designed to simulate the rapid temperature changes that a circuit board may experience during the startup and shutdown of an electronic device.
  • The ability to create customized test profiles allows manufacturers to test circuit boards under conditions that are closely related to their actual operating environments. This provides more accurate and meaningful test results, enabling them to better understand how the boards will perform in different scenarios and make targeted improvements to enhance reliability.
• Optional Test Accessories
  • The constant climatic test chamber can be equipped with a variety of optional test accessories to meet specific testing requirements. These accessories can include power supplies, data acquisition systems, vibration tables, and dust generators. For example, a power supply can be used to apply electrical loads to the circuit board during the test, simulating its actual operating conditions. A data acquisition system can be used to monitor and record parameters such as voltage, current, and resistance in real - time, providing valuable insights into the board's performance. A vibration table can be added to simulate the mechanical vibrations that circuit boards may experience during transportation or operation, while a dust generator can be used to test the board's resistance to dust and particulate matter.

User - Friendly Operation and Monitoring

• Intuitive Control Interface
  • The chamber is equipped with an intuitive control interface that simplifies the operation process. The interface allows operators to easily set and adjust test parameters, such as temperature, humidity, test duration, and test profiles. It also provides a clear display of the current test status, including the actual temperature and humidity values, elapsed test time, and any error messages. The user - friendly design ensures that even operators with limited technical expertise can efficiently conduct tests on circuit boards.
• Remote Monitoring and Control
  • Many models of the constant climatic test chamber offer remote monitoring and control capabilities. This feature is highly beneficial for manufacturers and quality control professionals, as it allows them to monitor the test progress and adjust the test parameters from a remote location, such as an office or a control center. This is especially useful for long - term tests or when multiple tests are being conducted simultaneously. Remote monitoring and control enable timely intervention in case of any issues, ensuring the smooth and efficient operation of the testing process.
