Control and test groupList of control and test operations

1. 100% receiving inspection (RI)

1.1. Appearance and marking condition inspection.

1.2. Parametric and functional check in normal climatic conditions.

2. 100% screening tests (011)

2.1. Thermal cycling.

2.2. Leakage monitoring.

2.3. Burn-in testing.

2.4. Measuring parameters at the extreme values of operating temperatures.

3. 100% diagnostic non-destructive testing (DNDT)

3.1. Electrical testing by rigorous rules.

3.2. Measurement of electrical parameters which are not included in specification («m» -characteristics and CVC for PS and PL. nonlinearity of CVC resistors by G-d harmonics, etc.), which are criterias to identify potentially unsafe products.

3 3. Calculation of the drift of electric parameters after burn-in testing.

3.4. X-ray-TV analysis.

 

4. Destructive physical (sampling) analysis (3-4 samples from each EEE lot)

4.1. Marking permanency check.

4.2. Solderability.

4.3. Control of moisture in the package.

4.4. Mechanical strength of external leads.

4.5 Visual internal control (after the removal of the lid from the PS and PP).

4.6. Die and metallization quality control using scanning electron microscope and X-ray microanalyzer.

4.7. Internal bonding strength control.

4.8. Die shear test.
