The total thermal resistance of a package (θ

package (case), surface (θ
terms are related by the equation:

dent and can be minimized by such thermal management techniques as heat sinks,
ambient air cooling and thermal convection. Thus, good thermal management on the
part of the user can significantly reduce θ
tution of θ
temperature.
The microcircuits shall meet all mechanical environmental requirements of MIL-STD-
883 for class B devices.
The document where are defined the marking are identified in the related reference doc-
uments. Each microcircuit are legible and permanently marked with the following
information as minimum:

Is in accordance with MIL-M-38510 and method 5005 of MIL-STD-883. Group A and B
inspections are performed on each production lot. Group C and D inspections are per-
formed on a periodical basis.
All static and dynamic electrical characteristics specified and the relevant measurement
conditions are given below.
