This part is the 11th part of GB/T 4937.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This section uses the translation method equivalent to IEC 60749-11.2002 "Semiconductor device mechanical and climatic test methods Part 11.

Rapid temperature change double liquid tank method.

--- The footnote number in the table is changed from "1, 2, 3" to "a, b, c".

1 Scope

This part of GB/T 4937 specifies the test method for rapid temperature change---two-tank method. When device identification can be used

The gas-air temperature cycle can also be measured by rapid temperature change---the two-tank method, the air-air temperature cycle test is preferred.

This test can also use a small number of cycles (5 times ~ 10 times) to simulate the effect of the heating liquid of the cleaning device on the device.

This test is applicable to all semiconductor devices. This test is considered to be destructive unless otherwise stated in the relevant specifications.

This test is basically the same as GB/T 2423.22-2002, but in view of the special requirements of semiconductor devices, the terms of this part are adopted.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1

Load load

The load consists of the test sample and the fixture used to fix the sample during the test.

Note. The maximum load is the maximum mass of the sample and fixture that can be placed in the tank's working area and that meets the specified temperature and time.

3.2

Monitoring sensor monitoringsensor

Calibrated and installed in a suitable position to indicate the same temperature as the worst-case location of the sample.

Note. The worst case sample position is determined by the period characteristic of the worst case load temperature.

3.3

Worst case load temperature worst-caseloadtemperature

Insert the temperature of the sample indicated by the thermocouple at the center of the load.

3.4

Sample specimen

Test device or individual.

3.5

Transfer time transfertime

The time it takes for the load to be removed from one tank to the other.
