The total thermal resistance of a package (
θ
JA
) can be separated into two components,
θ
JC
and
θ
CA
, representing the barrier to heat flow from the semiconductor junction to the
package (case), surface (
θ
JC
) and from the case to the outside ambient (
θ
CA
). These
terms are related by the equation:
θ
JA
=
θ
JC
=
θ
CA
θ
JC
is device related and cannot be influenced by the user. However,
θ
CA
is user depen-
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
CA
so that
θ
JA
approximately equals
θ
JC
. Substi-
tution of
θ
JC
for
θ
JA
in equation
(1
) will result in a lower semiconductor junction
temperature.

Mechanical and
Environment
The microcircuits shall meet all mechanical environmental requirements of MIL-STD-
883 for class B devices.
Marking
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:
ATMEL Logo
Manufacturer’s Part Number
Class B Identification
Date-code of Inspection Lot
ESD Identifier if Available
Country of Manufacturing
Quality Conformance
Inspection
DESC/MIL-STD-883
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.
