Thermal Enclosure Assembly for Accelerated Testing of
System Option Cards
describes an enclosure assembly for thermal
testing of personal computer system option cards.
Conventionally, an enclosure is used to accommodate a custom
hand-wired personal system board in a laboratory oven. This
enclosure is cooled with air from outside the oven to provide an
amiable climate for it. Attached to the system board are up to eight
extender cards. These place the option cards outside the enclosure
into the heated environment to be tested. The heated environment is
meant to accelerate failures on the option cards under test for early
failure product analysis. The system board requires hard-wiring,
cable hookups and checks to be made at each series of tests. This
requires a lengthy setup time.
assembly, disclosed herein, is shown in the
drawing. It is designed and built with independent panels or drawers
which slide independently in and out of the assembly. Each panel is
capable of having two system boards permanently wired to it. This
provides the assembly with up to eight system boards, each having up
to eight option cards or a total of sixty-four option cards could be
tested at one time. It also allows for testing of up to four
different models of system boards at a given time by virtue of the
four independent drawers. Each drawer is prewired. This affords
easy changing of board models....
