The rapid temperature change test chamber is a cycling chamber designed to facilitate the observation of thermal shock tests.
Due to the increasing number of issues that affect the reliability of electronic devices, printed circuit boards and their reliability, there is a need for a more suitable method to evaluate them. The rapid temperature change test chamber states that the rate of change in temperature of the test sample should be less than 15 degrees Celsius per minute. This is the main difference between the heat shock test and this method. The rapid temperature change test produces repeatable results and determines compliance with standards such as JEDEC (JESD 22A104B span>).
Features:
- Temperature change rate of 5 ~ 15 ℃ / min.
- A dry ventilation system protects the sample surface from drying out during rapid temperature changes.
- Modular manufacturing process.
- An intelligent 32-bit control system with a beautiful screen. USB and Ethernet interfaces
- 4-Ih. Programmable power supply To ensure safety, ON/OFF output control.
- Patented wireless technology improves test accuracy.
- Thermal protectors and sensors protect the sample at room temperature.
- Windy and clear.
- Test data is used to coordinate network video monitoring. Non-self-generating humidity chamber (ESC system)
- Motion control for APP.
- Water supply device with ultrapure filter system and water shortage alarm. (ECS-system)
- Good control at low humidity: 20/10% RH. Environmental servo refrigerant flow controller energy saving and heat/quick rate
- This type of operation is unique because it returns the temperature of the test area to R.T. after each test. This protects the condition of the sample.
- Automatic reminders for hardware version maintenance and software error logging.
- Remote operation and video CD for equipment operation.
For quality control:
The company has created a new rapid change room to facilitate product testing for industrial workers. This room is used for quality control and product testing. This facility is used to test the reliability and performance of semiconductor chips, optical communication modules and other test systems.
Two 1.5 kW Tecumseh French compressors are used in the rapid temperature change test room. The cooling power change rate is 3℃/min. The machine can perform online product monitoring according to the temperature change rate. Automatic volume and air speed adjustments are made. This ensures that the temperature in the test area is distributed properly. An electronic expansion valve minimizes surface differences and allows precise control.
Fast heat exchanger housing is a popular choice for 5G optical modules or fiber optic communication components. Almost all optical devices must pass through high and low temperatures before leaving the factory. Each material has a different rate of thermal expansion. Only a change in temperature can test the risk of material failure.
Thermal cycle test to determine the rate of heating and cooling at least once per minute. The device must remain at least 10 minutes to reach room temperature. For interior light modules, it is acceptable to cycle 100 times. The external heat module requires 500 thermal cycles. The product is also more stressed by rapid changes in temperature. This improves the efficiency of stress analysis. If the load is more than 100kg, linear 15 ℃ / min in the heating and cooling load, the temperature deviation in the test room is + -2.0
This room is used for testing the mechanical properties of electronic products, their flexibility and stress testing under the specified temperature conditions of rapid change or slow temperature change. You can test and evaluate the physical and other characteristics of the product. The door can be opened or closed without any effort. You can add or remove tested samples from the workspace.
The rapid temperature change test room has a large and spacious viewing window:
- Use triple-glazed windows with energy-saving fluorescent lamps.
- There is no cleaning required for waste.
Cover Design:
- The entire building follows a set plan.
- The interior is made of 1.0mm SUS 304 B stainless steel. The exterior is 1.0mm cold rolled steel plate, covered with plastic. The cover is a very important glass cover.
- The door is sealed with a double layer of silicone rubber.
- The observation window is a multi-layered clear glass measuring 350 x 500 mm. A special electric heating wire, with a voltage of 36V, is used to protect the heating cable from glass icing at low temperatures. Lights are also provided for viewing.
- Part of the housing has a 50mm hole with a plug. This plug is made of low foam, high and low silicone rubber, which works well in heat insulation.
- The temperature sensor is located in the air intake.
- The top air condition for the writing room is the bottom air refrigeration unit and the top air.
Heating system:
- Heating by heating through the heating tube and the installation of the element using solid state relays. Control system for low-level test room: click, touch
- Display mode: colour LCD touch screen Chinese display
- Graphical Presentation: Detailed presentation of parts of the maintenance program
- Parameter Retention Period: Data may be retained for up to five years after successful completion. There are 1 to 50 events (or more than 50 events).
- Part of the program: From part 1 to 64, they can be linked together and killed together.
- It can allow the user to change the time, temperature and humidity settings.
- Special repairs are available for equipment breakdown and maintenance.
- Wait for the function to run while the program is running.
- Career progression program.
- Program termination function
- With the power failure recovery function.
- By operating the lock interface. Recording function: can record parts and test data in less than 100 days. You can also ask summer questions at any time up to 100 days. This can be shipped via USB 2.0. Print the record format and create a data report on the PC. (Equivalent to undocumented record services). It also has a self-diagnostic function in case of power failure.
- Computer Monitoring System: This control system is able to transfer data and monitor operations through the computer’s Ethernet communication interface.
