Circuit Check is an American company with about 225 employees and seven direct operations in six countries (the U.S., Canada, Mexico, United Kingdom, China, and Malaysia).
Headquartered in Maple Grove, Minnesota, it is one of the largest manufacturers of electronic and mechanical test fixtures in North America,[1] .
One, the pneumatically-actuated "clamshell" test fixture, electrically probes a circuit board from both sides.
"pogo pin") exerts several ounces of force on the device under test (DUT).
Such force is sufficient to deform the DUT (a printed circuit board, for example) to the point where the attached inflexible electronic component packages (such as Ball Grid Arrays) may fracture, or their solder joints may fail.
