Q: Page 105. For all components the acceleration factor for the mechanical stress is raised with a power of 1.5; but for wired board the stress is raised with a power of 2.8 (page 100)
A:
Page 100, wired board: Because of the special construction process of this model, the
acceleration factors for wired board are specific. So this power of 2.8 is correct.
Page 105, hard disk: The acceleration factor for hard disk shall be 1.5. The right formula is:
