T/UNP 533-2025 Aluminum-based copper-clad laminates thermal resistance test method

Scope

Main technical content: This standard specifies detailed specifications for the thermal resistance test of aluminum-based copper-clad laminates, ensuring the accuracy and reliability of the test. The test principle is based on Fourier's law of heat conduction, calculating the thermal resistance by measuring the temperature difference, heat flow, and area, and conducting stability and repeatability tests. Test preparation involves aspects such as environment, equipment, personnel, sample pretreatment, size measurement, and temperature setting, with strict requirements for temperature and humidity, equipment accuracy, personnel skills, sample specifications, and temperature ranges. The test steps include basic testing, stability testing, and repeatability testing, with specific operating procedures and evaluation standards specified for each. The test report must record information such as test equipment, samples, test conditions, results, exception handling, and conclusion evaluation, and data recording and modification must follow standard procedures.
