The GGB Industries MULTI-CONTACT WEDGE
allows for more chip design flexibility because it is custom
configured to your circuit. Four Wedges can be used at the same
time to probe a complete chip.
With its individually spring loaded, Beryllium-Copper tips,
the Multi-Contact Wedge provides reliable contacts, even when
probing non-planar structures. This reliable low resistance contact
is one of the keys to providing highly repeatable measurements.
The Multi-Contact Wedge also provides direct viewing of the probe
tips for accurate positioning.
When used with standard microwave probe stations the Wedges
can first be positioned to any microwave calibration standard
and then moved into position on the MMIC or Module to be tested.
The probe points on a Wedge can even be set to different depths
so that multi-level modules can be successfully probed. Any pitch
(tip spacing) from 50 to 1250 microns may be specified. Larger
pitch probes are available by special order. The probes can be
configured with Ground-Signal-Ground (G,S,G), Ground-Signal (G,S),
or Signal-Ground (S,G) tip footprints.
Connection to the Model 40A is through a female K connector
and is compatible with SMA and 3.5mm connectors. Connection to
the Model 50A is through a female 2.4mm connector. Connection
to the Model 67A is through a female V connector and is compatible
with the 2.4mm connector. Connection to the Model 110A is through
a W (1.1mm) or a 1.0 mm connector.
Many different
wiring configurations are available for the dc, power supply,
or medium frequency needles. Ribbon cable, coaxial cable, and
hook up wire are some of the types available. Our standard connectors
include banana plugs, BNC connectors, SMA connectors, (9, 15,
25, or 37) pin D-Subminiature connectors, (20 or 26) pin AMP-LATCH
receptacles, which are center and military polarized. The AMP-LATCH
receptacles have a double row of contacts on 0.1 inch centers
and will receive .025 inch square or round pins. Other connectors
can be specified.

The MCW-14 & MCW-26 Multi-Contact
Wedges by GGB Industries, Inc., are flexible alternatives
to providing either dc or power to a circuit for testing purposes.
Each wedge is custom fabricated to your circuit layout and offers
three alternative locations for capacitors, direct viewing of
probe needles for accurate positioning, and can be configured
with either a 14 pin or 26 pin connector. The connector consists
of a dual row of 0.025 inch square pins on 0.1 inch centers,
providing the user with a flexible and useful tie-in point.
Probe needles can be set to different depths so that
multi-level modules can be probed successfully. The unique design
of the MCW-14 and MCW-26 Multi-Contact Wedges ensures reliable
contacts, even when probing non-planar structures and allows
for easy positioning when used with any standard microwave probe
station.
