A bathtub curve consisting of three linear regions as a function of time (t), namely:

1. an infant mortality failure rate that decreases as landa(t) = C1 -C2t

2. A zero random failure rate.

3. A wear out region that varies as C3(t-t_0)

a) Sketch the bathtub curve, labeling each region carefully.

b) calculate f(t) and F(t) values in each of the three regions.

c) sketch and explain clearly what happens to the bathtub curve as component dimensions shrink further.

d) sketch and explain what happens to the bath tub curve as devices are powered under sucessive higher current voltage stressing.
