QUALIFICATION TESTS General Tests

Test flows are shown in Figure 2 and test details are given in Table 2. Not all tests apply to all devices. For example, certain tests apply only to ceramic packaged devices, others apply only to devices with NVM, and so on. The applicable tests for the particular device type are indicated in the “Note” column of Table 2. The “Additional Requirements” column of Table 2 also serves to highlight test requirements that supersede those described in the referenced test method. Any unique qualification tests or conditions requested by the user and not specified in this document shall be negotiated between the supplier and user requesting the test.
