Resistance can then skyrocket
from under 50 milliohms to
2-3 ohms. In addition, high
resistance readings may be
intermittent, which makes
it nearly impossible to find and
replace the problem probes.
Ostby Barton originated and
developed the Cyclo-Soldered
test probe. This unique process
provides a continuous, metallurg-
ically bonded unit ensuring low and
stable electrical constant resistance
from one end of the probe to the
other. When the bearing surfaces
become completely insulated by
contaminants, the spring (which is
silver soldered to the plunger and
barrel) takes over as the path of
least resistance and remains
constant throughout the probe’s
life. The maximum probe
resistance is limited to that of the
spring itself, which is typically
under one ohm.
available on selected probes shown
in this catalog. Please consult the
factory for more information.
High Current Probes
High current probes can carry 8-35
amps through a circuit. This is
especially useful in non PCB test
applications. The HC probe series
provides low constant electrical
resistance and excellent mechanical
life on a variety of test centers. The
special internal design provides
higher current carrying capacity
than “similar looking” probes. The
stainless steel springs permit use
in high temperature applications
while their high pressure provides
tip-to-target force minimizing
constriction resistance.
Cyclo-Soldered Probes
The actuation of your vacuum
fixture can pull solder fumes,
fluxes, dust and smoke from the
air. These elements are then
deposited, together with friction-
induced plating wear, on the
bearing surfaces of your probe.
To address this situation,
The Cyclo-Soldered process is

Five receptacle styles are available:
crimp, solder, wire wrap, round
pin, and Quick Connect™. Some
styles are only available in certain
sizes (see specific probe series).

lation tips.
Custom Probes
Ostby Barton has the industry’s
largest collection of custom probe
designs. We had electrical contact
design experience even before
electrical contacts were adopted
for ATE use.
the solution you need off the shelf.
But if your application demands a
more unique approach, our
engineers will work with you to
develop the probe that meets your
needs.
Ostby Barton creates more custom probe designs than
anyone else in the industry.
CRIMP
This reliable connection is used
primarily on smaller probe sizes in
high density applications where
wire wrap is not available or in
situations where probe plate thick-
ness inhibits the use of wire wrap-
ping. Push-on terminals can also
be used and are commercially
available from most connector
manufacturers.
SOLDER
This termination provides excellent
electrical integrity for high reliability
applications. It is used primarily in
low density situations.

WIRE WRAP
These terminations are strong and
provide excellent electrical integrity.
It is the most common termination
used in ATE fixturing. Connections
can be made quickly by skilled
technicians. Push-on terminals
which fit the standard .025" (0,63
mm) square post can also be used.
ROUND POST
Round Post receptacles with .025"
(0,63 mm) diameter posts are used
with .100" (2,54 mm) center con-
nectors and/or ribbon cable
assemblies for mass termination.
QUICK CONNECT™
Quick Connect termination provides
exceptional contact integrity and is
available only on SMT receptacles.
Connections can be made quickly
and wiring mistakes can be corrected
easily without damaging the
receptacles.
