real-world conditions.
Both sides of the UUT are studied since there are different thermal gradi-
from others, possibly causing uneven overheating.

spreading. Both longitudinal and transverse airfl ow studies are
possible by rotation of this carrier board since there are often
signifi cant differences in the heat dissipation in the two airfl ow
directions. The combination of both adjustable airfl ow, adjustable
ambient heat and adjustable Input/Output currents and voltages
mean that a very wide range of measurement conditions can be
studied.
