18、es. It is an accelerated test designed to indicate types of structural and mechanical weaknesses not necessarily detected in shock and vibration test. It may be used as a high stress (destructive) test to determine the mechanical limits of the package, internal metallisation and lead system, die or
19、substrate attachment, and other elements of the microelectronic device. When proper stress levels have been established this test method may also be employed as a non-destructive in-line 100 % screen to detect and eliminate devices with lower than normal mechanical strengths in any of the structural
20、 elements. In general, this acceleration steady-state test method is in conformity with IEC 60068-2-7 but, due to specific requirements of semiconductors, the clauses of this standard apply. 2 Normative references The following referenced documents are indispensable for the application of this docum
21、ent. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

For devices with internal elements mounted with the major seating plane perpendicular to the Y axis, the Y 1orientation shall be defined as that one in which the elements tend to be removed from th
24、eir mount. Unless otherwise specified, test condition E shall apply.
