Problem-free probing

The Agilent wedge probe adapter elimi-

nates many of the frustrations associated

with probing surface mount components.

If you’ve ever accidentally shorted IC pins

together, experienced electrical and/or

mechanical problems with soldering small

wires onto leads, or gotten frustrated jug-

gling multiple probes while you’re trying

to operate your scope, the Wedge was

designed with you in mind.

Make the inaccessible

accessible

When you use the Wedge, you don’t have

to worry about shorting IC pins together

on a delicate component–or worse yet,

on an irreplaceable prototype. The Wedge

is easy to insert and it stays put. There’s

no need to solder small wires onto leads.

The Wedge is mechanically non-invasive,

so you won’t damage the legs of the IC.

Instead, you’ll have easy access to hard-

to-reach components.

Operating characteristics

Electrical reliability

The Wedge makes two contact points with

each leg of the IC. This redundant physical

connection increases the electrical reliability

of the connection. Also the Wedge’s low

capacitance and inductance provides superior

performance to many other alternatives.

The Wedge probe adapter connects directly

to 1145A/1155A active probes and the dual

lead adapter provided with the 1160A-65A

passive probe family and N2877A/N2879A

accessory kits for use with N287xA Series

passive probes.

IC clip kits

As an inexpensive solution for probing fine-

pitch ICs, the 10072A SMT Kit includes 10 IC

clips and 2 dual-lead adapters that connect

the clips directly to 10070-family probes.

The 10075A 0.5-mm IC clip kit is ideal for

connecting to IC’s as fine as

0.5 mm. The clip body allows many clips to

be mounted side-by-side. The kit includes

four 0.5-mm IC clips and two dual-lead

adapters that connect the IC clips directly to

10070-family probes.
