1. Product Name and Purpose

2. Product Features

• Robust and Insulated Chamber Structure
  • The chamber is constructed with heavy-duty, heat-resistant materials that can withstand the intense thermal stresses. The walls are made of high-strength steel alloy, combined with advanced thermal insulation layers to minimize heat transfer between the hot and cold zones. The door is engineered with a reliable sealing mechanism and a viewing window, allowing operators to monitor the testing process without compromising the chamber's integrity. The interior is designed with adjustable racks and fixtures, enabling the accommodation of variously sized and shaped components and ensuring uniform exposure to the thermal shock conditions.
• Precision Temperature Control System
  • Temperature Range and Cycling: Capable of achieving a wide temperature range, typically from -60°C to +150°C. The system can execute rapid temperature cycling between the hot and cold zones, with a transition time as short as a few seconds. This is essential for mimicking the abrupt temperature changes that components may experience in real-world applications, such as when a device is powered on or off, or when exposed to external heat sources. The temperature control is accurate to within ±0.3°C, providing reliable and repeatable test results.
• Intuitive Control Panel and Data Acquisition Interface
  • The control panel is designed for user-friendliness, allowing operators to easily set and adjust test parameters such as temperature levels, dwell times in each zone, and the number of thermal shock cycles. It provides real-time displays of the current temperature in both zones, the status of the testing process, and any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system that records all relevant test data. This includes temperature histories, cycle times, and any observable changes in the physical, electrical, or mechanical properties of the components. The data can be stored in a built-in memory or exported to external storage devices for further analysis. The system can also generate detailed test reports in various formats.
• Safety Features and Alarms
  • To ensure the safety of operators and the protection of the test samples and the chamber itself, a range of safety features is incorporated. These include over-temperature and over-current protection systems, emergency stop buttons, and alarms for abnormal temperature fluctuations, equipment malfunctions, or any other safety-related issues. The chamber is also equipped with proper ventilation and exhaust systems to handle any potentially harmful gases or vapors that may be generated during the testing process.

3. Specific Parameters

• Temperature Range and Accuracy
  • The -60°C to +150°C temperature range with ±0.3°C accuracy offers a comprehensive testing spectrum. Different components have different temperature tolerances and performance characteristics. For example, electronic components may experience changes in electrical conductivity or mechanical stress at extreme temperatures. The accurate temperature control ensures that the test conditions are precisely maintained, allowing for a detailed assessment of component behavior.
• Thermal Shock Cycle Parameters
  • The chamber can be programmed to perform a specific number of thermal shock cycles, typically ranging from 10 to 500, depending on the requirements of the IEC-60068-2-14, Test Na² standard and the nature of the components. The dwell time in each temperature zone can also be adjusted, from a few minutes to several hours. This flexibility enables manufacturers to simulate a wide variety of real-world scenarios and evaluate the long-term durability of components under different thermal shock conditions.
• Testing Volume and Payload Capacity
  • The chamber offers a customizable testing volume, usually ranging from 2 m³ to 10 m³, to accommodate a significant number of components. The payload capacity is designed to handle heavy and bulky components, with a maximum capacity of up to several tons. This allows for the testing of both individual components and small assemblies.
• Data Sampling Frequency and Resolution
  • The data acquisition system samples data at a frequency of up to 600 Hz. The temperature data has a resolution of 0.1°C. This high-resolution and frequent sampling enable the detection of even the slightest temperature changes and trends, providing valuable insights into the behavior of the components during thermal shock testing.

4. Product Functions

• Accurate Simulation of IEC-60068-2-14, Test Na² Test Conditions
  • The chamber replicates the exact thermal shock conditions specified in the IEC-60068-2-14, Test Na² standard. This is crucial as components must meet these requirements to ensure their compliance and reliability. By subjecting the components to these precise simulations, manufacturers can be confident that their products will perform as expected in real-world applications.
• Product Design Optimization and Quality Control
  • Through a series of tests on different component prototypes, the data obtained from the chamber can be used to optimize product designs. Engineers can analyze the performance of various materials, geometries, and manufacturing techniques under thermal shock stress. The chamber also serves as a vital tool for quality control, ensuring that each production batch of components meets the required standards. For example, if a particular connector shows signs of loosening after a certain number of thermal shock cycles, the design or manufacturing process can be adjusted to correct the issue.
• Research and Development Support
  • In the field of component research and development, the Custom Thermal Shock Chambers offer valuable insights. Researchers can use them to study the fundamental properties of new materials and their interactions with thermal shock. They can explore innovative designs and technologies that result in more resilient components. For instance, materials scientists can test the performance of novel composites or advanced heat sinks under IEC-60068-2-14, Test Na² test conditions, using the chamber to evaluate their potential for future applications.
• Compliance Testing and Certification
  • The equipment is essential for conducting compliance testing to meet the IEC-60068-2-14, Test Na² standard. The electronics and manufacturing industries have strict regulations regarding component performance, and the test results obtained from the chamber can be used to certify that the components meet these standards.
