Abstract
An example test system includes a plenum including an air inlet and a rack including slots to hold devices under test. The rack is adjacent to the plenum. The slots are arranged on the rack in a matrix such that part of each device held in a slot borders the plenum and is in fluid communication with the air inlet. One or more blowers are configured to force temperature-conditioned air into the air inlet of the plenum to thereby increase air pressure in the plenum and force the temperature-conditioned air over the devices and out of the plenum.
Claims26
A test system comprising:
- a first plenum comprising an air inlet;
- a rack comprising slots to hold devices under test, the rack being adjacent to the first plenum, and the slots being arranged on the rack in a matrix such that part of each device held in a slot borders the first plenum and is in fluid communication with the air inlet;
- one or more blowers to force temperature-conditioned air into the air inlet of the first plenum to thereby increase air pressure in the first plenum and force the temperature-conditioned air over the devices and out of the first plenum;
- and
- a second plenum, the slots being arranged on the rack in the matrix such that part of each device held in a slot also borders the second plenum, the temperature-conditioned air being forced over the devices into the second plenum.
