Connecting piece

1. Test Preparation

Select test equipment:

Choose a precise temperature control of the thermal shock test chamber.

Ensure that the test chamber can meet the required temperature range and impact conditions.

Prepare the sample:

Prepare a sufficient number of copper tab samples for testing.

According to the test needs, you can choose different copper connection piece size, shape and connection.

Installation sample:

The copper connection piece sample is installed in the test box in the appropriate position.

Make sure that the sample and the test chamber wall have enough space to facilitate air circulation.

2. Set Test Conditions

Temperature range:

According to the test requirements, set the high temperature and low temperature range.

Common temperature ranges may include -40°C to 150°C or more.

Impact time:

Set the holding time at each temperature, and the transition time from high temperature to low temperature or from low temperature to high temperature.

the conversion time is typically short to simulate rapid temperature changes.

Cycles:

According to the test needs, set the test cycle times.

Cycle times can be based on the product's expected life or the actual working environment to determine.

3. to test

Start the test:

Start the cold and hot impact test chamber, according to the set temperature range and impact time for testing.

Monitor the test process of copper connection piece temperature changes, and record the relevant data.

Observation and recording:

In the test process, observe the copper connection piece appearance and structure for abnormal changes.

Record the temperature stabilization time, temperature fluctuation range, and any abnormal phenomena at each temperature.

4. Test End and Evaluation

Check the sample:

At the end of the test, remove the copper tab sample for careful inspection.

Check the sample for deformation, cracking, oxidation, discoloration and other abnormalities.

Performance test:

According to the need, the test of the copper connection piece for electrical performance testing, such as resistance, insulation strength, etc.

Evaluate whether the tested sample's performance meets the requirements.

Result analysis:

Analyze the test data to evaluate the copper connection piece in the high temperature rise and cold and thermal shock conditions of performance stability and reliability.

According to the test results, put forward improvement measures or optimization suggestions.

Write a test report:

The test process, test data, test results and analysis, etc. into a test report.

the report shall detail the test conditions and test results for subsequent analysis and reference.
