QA Technology's 075-40 and
100-40 Series long-stroke probes are
designed for use in dual-level (Functional/In-Circuit)
test fixtures. The long-stroke probes
are easily mixed with their standard-stroke
counterparts from the 075-25 and 100-25 Series. Long-stroke
and standard-stroke probes with the same
center spacing install in identical sockets,
mounted at the same set height. This allows
the probes to be interchanged freely from
one socket to another as test needs dictate.
As shown above, the long-stroke probe
tips are .150 [3.81] higher than neighboring
standard-stroke tips when the fixture
is not actuated. In the functional test
position, the long-stroke probes are deflected
.060 [1.52], leaving .090 [2.29] clearance
to the tips of the standard-stroke probes.
During in-circuit test, deflection of
the long-stroke probes is .317 [8.05],
and the standard-stroke probes are deflected
.167 [4.24] (the recommended two-thirds
travel position). |
