Preconditioning of High and Low Temperature Dampening Tester should meet the conditions
High and low temperature suppression tester, also known as high and low temperature impact test box, suitable for electronics, auto parts, plastic and other industries, testing a variety of materials on the high and low temperature repeated impact capacity. Testing the product in the thermal expansion and contraction caused by chemical changes or physical damage, to ensure product quality.
High and Low Temperature Dampening Tester can be widely used in electrical and electronic components, automation components, communication components, auto parts, metal, chemical materials, plastics and other industries, defense industry, aerospace, arsenal, BGA, PCB pull, electronic chip IC , Semiconductor ceramic and polymer materials, physical changes in the test of its material on the high and low temperature of the repeated resistance and product thermal expansion and contraction of the chemical or physical damage, to confirm the quality of the product, from the precise IC to Heavy mechanical components, will be used, is the field of product testing is essential to a test box.
Brief description of the operation method of High and Low Temperature Dampening Tester:
1, pretreatment: the test sample placed in the normal test atmospheric conditions, until the temperature stability.
2, the initial test: the sample will be tested with the standard requirements, meet the requirements directly into the high and low temperature impact test box can be.
3, test: 1) the test sample should be placed in the test room according to the standard, and the test chamber (room) temperature rose to a specified point, to maintain a certain time to test the sample to achieve temperature stability, whichever is longer.
2) After the end of the high temperature phase, the test sample was switched to a low temperature test chamber (room) adjusted to -55 ° C for 5 hours or until the test sample reached the temperature stable for a long time.
3) After the end of the low temperature stage, the test sample was switched to a high temperature test chamber (room) adjusted to 70 ° C for 5 hours or until the test sample reached the temperature stable for a long time.
4) Repeat the above experimental method to complete three cycles. Depending on the size of the sample and the size of the space, the time may be slightly erroneous.
4. Recovery: After the test sample has been removed from the test chamber, it should be restored under normal test conditions until the test sample reaches the temperature stability.
5, the final detection: control standards in the degree of damage and other methods to test the results of assessment.
For more information on the High and Low Temperature Dampening Tester, welcome to continue to pay attention to the company's Web site to understand!
High and low temperature suppression tester is mainly used in aviation, military, ship, electrician, electronics, instrumentation, medical equipment and other industries, can also be used in institutions of higher learning, scientific research laboratory, commodity inspection arbitration, technical supervision departments, building materials, ceramics and other fields , All the functions of the use of computer control, the Department of self-developed software, a good user interface, so that the user's operation and monitoring are more simple and intuitive to keep the function you can run the program to maintain the state, you can temporarily change this Value, you can set the time and parameters on the screen, so that cooling, heating, blue transfer switch, according to the set value automatically.
High and Low Temperature Dampening Tester daily maintenance work analysis:
In order to ensure that the high and low temperature test instrument is often in a good state of technology, ready to run, reduce the downtime, improve the mechanical integrity rate, utilization, reduce mechanical wear, extend mechanical life, reduce mechanical operation and maintenance costs, to ensure safety Production, must be strengthened on the High and Low Temperature Dampening Tester equipment maintenance work:
High and Low Temperature Dampening Tester maintenance must implement the "maintenance both, the main prevention" principle, so that regular maintenance, mandatory, correct handling, maintenance and repair of the relationship, not allowed to only do not raise,
Each team must be in accordance with the mechanical maintenance procedures, maintenance categories do all kinds of machinery maintenance work, no undue delay, the special circumstances need to be approved in charge of the Commissioner after the extension of maintenance, but generally not more than half of the provisions of the maintenance interval.
