MIL-STD 883 Stabilization Bake Testing

MIL-STD-883 stabilization bake testing helps determine the effect on microelectronic devices of storage at elevated temperatures without applying electrical stress. This method can be used as a preconditioning treatment. It also can be used in a screening sequence before conducting other tests. The MIL-883 stabilization bake test should not be used to determine device failure rates for anything other than storage conditions.

End point and, where applicable, intermediate measurements may be made on a serialized device basis. They may also be made on the basis of a histogram distribution by total sample. This is to increase the sensitivity of the test to parameter degradation. Or to the progression of specific failure mechanisms with time and temperature.

All MIL-STD 883 temperature testing should take place in the temperature laboratory. This ensures a controlled environment which will provide the most accurate test results. Method 1008.2 stabilization bake testing requires a chamber capable of maintaining the specified temperature. Suitable electrical equipment to make the specified end point measurements is also necessary.

Keystone Compliance is a stabilization bake testing lab with significant MIL-883 temperature testing experience. Our experts understand the requirements of stabilization bake compliance testing. Keystone Compliance is able to provide temperature certifications for a variety of products. The following information is extremely technical in nature, as it is a summary of  MIL-STD 883 stabilization bake testing.

What is the Procedure for the Best Stabilization Bake Testing?

Devices should be stored at the specified ambient conditions for the specified time. The time at high temperature must allow for the total mass of each device to reach the specified temperature. This should happen before the specified time duration begins.

Between 24 hours before and 72 hours after the test, the device is removed from the specified test condition. It is then allowed to reach standard test conditions. When specified, end-point measurements should be completed within 96 hours after the device is removed from the specified test condition. When specified (or at the manufacturer’s discretion) intermediate measurements are made at intermediate points.

What Test Conditions Exist for the Method of MIL-STD-883 Temperature Testing?

The ambient test temperature is indicated by specifying a test condition letter from the following table. The specified test temperature is the minimum actual ambient temperature. All devices in the working area of the chamber are exposed to the specified test temperature.

Make whatever adjustments necessary to assure this temperature. Adjustments may include the chamber profile, loading, location of control or monitoring instruments, and the flow of air. Therefore, calibration is accomplished on the chamber in a fully, loaded, unpowered configuration. The indicator sensor is located at, or adjusted to reflect, the coldest point in the working area.

Unless otherwise specified, test condition C minimum, with the minimum time duration and temperature specified, will apply. Unless otherwise specified, the test duration for all other test conditions shall be 24 hours minimum. Time and temperature requirements for different test conditions are detailed in the table below.
