What is a Spring Contact Test Probe?
Test probes - test pins - spring probes - pogo pins; these are all generic terms to describe a component whose spring loaded tip will
provide a reliable electrical contact to a target whose distance away may well be indeterminate. The traditional use for them is to
make contact with printed circuit boards (PCBs) or electrical components, in order to test functionality and to measure the value of
the components. They are widely used in vacuum test fixtures associated with automatic test equipment (ATE). They are also used
inside a functional test station as part of a larger production line.
The test probe is comprised of a metal tube, ready assembled with a spring and contact plunger, supplied as a one-piece item.
They are usually gold plated as gold is an excellent electrical conductor and is resistant to corrosion. The electrical cable is
generally connected to a receptacle which the test probe inserts into. The use of a receptacle allows the test probe to be removed
for cleaning or replacement without having to dissconnect the electrical cable (see illustration below).

How to use General Purp
Product selection
Once you have decided which series of general purpose test probe best suits your application, you will need to select a suitable tip style. The table below illustrates
which of the tip styles is likely to be most effective in a particular situation.
Most of our series have a choice of spring pressure. A lighter spring is preferred in test applications where the test point is considered clean or uncontaminated.
The heavier spring will help the probe tip to penetrate better through any contamination. A lighter spring may have to be a consideration in test fixtures with
large quantities of probes, or in situations where the density of probes is very high in a small area.

The receptacle is a type of socket that fits into the drilled hole in the probe plate or block. The test probe slips inside the receptacle allowing it to become a
replaceable item as the electrical cable is connected to the tail of the receptacle. There are several versions of receptacle (see below) depending on your preferred
choice of cable termination - providing it is available in the specific probe series.

pose Test Probes and Receptacles
Fitment and usage
Example fitment methods are shown for each series in the General Purpose Test
Probe section starting overleaf. The receptacle is usually mounted into a probe
plate. This plate can be made of resin-laminated fibreglass (types such as G10 or
FR4), or plastic materials such as nylon, perspex or polycarbonate. The thickness
should be such that it will support the total spring pressure of all probes without it
bending significantly. For very large arrays of probes it may be necessary to put
some support pillars underneath to minimise this problem. For general purpose
test applications, an 8-10mm thickness of material is recommended.
Carbide drills are best suited for drilling holes for receptacles in the harder
composite or fibre based materials. Commonly available high-speed drills (HSS) are
suitable for plastics, such as peek, nylon or perspex. A few sizes of carbide drills
have an option of longer flute length for thicker probe plate materials.

How to fit a receptacle into a drilled hole in a general purpose test position
TA5
1. Inserting the receptacle
The receptacle may be flush
mounted or set raised slightly
above the probe. In most general
purpose test situations the
receptacle height is set to flush.
2. Using a receptacle insertion tool
Receptacle insertion tools are required for inserting the receptacle’s press-ring into the
hole without damaging it (see table above for tool selection). This is particularily
important if you are using harder materials for the probe plate. Insert the pin of the
tool into the receptacle and tap the insertion tool gently
with a hammer, until the receptacle is set to the desired
height. See box 2a for instructions using epoxy fitment.
The receptacle should slip down
unassisted until the press-ring
rests against the probe plate.

3. Inserting the probe

press home. The probe’s body is
normally fully enclosed within
the receptacle.

2a. Using epoxy
It is perfectly acceptable to use the press-ring as
a shoulder to stop the receptacle from pushing
into the hole. However, you will have to bond
the receptacle in place using a suitable epoxy.
We also offer receptacles with stop rings to allow
flush mounting with epoxy.

Notes: If you wish to use a probe without a receptacle, then these should be bonded into the probe plate. A correctly sized hole will be required. You may need to experiment with this.
After care
A regular maintenance programme for your probes will help you achieve the
maximum probe performance and lifespan. The necessary frequency and
method of the maintenance/cleaning programme depends on your production
environment, the type of equipment and the probe series used.
Contamination left behind on the probe tip is the primary cause of probe contact
problems. This is often caused by a bi-product of the soldering process of either
soldering flux or a solder residue. Other local contaminants such as dust, fluff,
oil and grime can cause more temporary problems.

How to use ATE Tes
Information
Product selection
ATE probe tip selection
There are three sizes of ATE test probes for the three standard test centre
spacings (pitch) commonly used on printed circuit boards (PCBs). See previous
page. Once you have selected the probe size which will best suit your application
you will need to select suitable tip styles. The table below shows which of the
tip styles is likely to be most effective for each particular test target.
Spring pressure
Most series have a wide choice of spring pressure. A lighter spring is preferred
in test applications where the test point is fairly clean or uncontaminated. The
heavier and extra heavy springs will help the probe tip to penetrate better
through any contamination. A lighter spring may have to be a consideration in
test fixtures with large quantities of probes, or in situations where the density
of probes is very high in a small area.
Be careful not to fit a probe spring force, which in total is more than the fixture

The receptacle is a type of socket that fits into the drilled hole in the probe plate. Its use allows the probe to be a replaceable item for easy maintenance, without
having to disconnect the electrical cable. There are several versions of receptacle (see below) depending on your preferred choice of cable termination - providing
it is available in the specific probe series.

st Probes and Receptacles
Fitment and usage
The receptacle is usually mounted into a probe plate. This plate can
be made of resin-laminated fibreglass (types such as G10 or FR4),
or plastic materials such as nylon, perspex or polycarbonate. Usually,
the probe plate used is made from fibreglass. Tungsten carbide drill
bits are required to drill holes in this material. The thickness of the
probe plate should be such that it will support the total spring
pressure of all probes without it bending significantly. For very large
arrays of probes it may be necessary to put some support pillars
underneath to minimise this problem. For general purpose test
applications, an 8-10mm thickness of material is recommended.

How to fit a receptacle into a drilled hole in an ATE test fixture
TA2A
TA3
1. Inserting the receptacle
The receptacle may be flush mounted, or
set raised slightly above the probe plate.
In most ATE situations the receptacle’s
height is set raised. The receptacle should
slip down unassisted until the
press-ring rests against the
Flush
fitment tool
probe plate.
2. Using a receptacle insertion tool
Insert the pin of the tool into the receptacle (you will need to set the height required on the
adjustable tool). Tap the end of the tool with several light taps until the receptacle is set to the
required height. See the table above for tool selection.
3. Inserting the probe
Remove the tool and insert the probe rearwards and press home with a probe insertion
tool (see above). The probe’s body is normally fully enclosed within the receptacle.

After care
A regular maintenance programme for your probes will help you achieve the
maximum probe performance and lifespan. The necessary frequency and
method of the maintenance/cleaning programme depends on your production
environment, the type of equipment and the probe series used.
Contamination left behind on the probe tip is the primary cause of probe contact
problems. This is often caused by a bi-product of the soldering process of either
soldering flux or a solder residue. Other local contaminants such as dust, fluff,
oil and grime can cause more temporary problems.

ATE Test Probes
1.27mm/0.050” centre spacing
LPC1, ST-LPC1 & LF-LPC1 Series
The LPC1 series is the universal size for use at 1.27mm test centres in the majority of ATE test fixtures. It has a
very wide range of tip styles for almost all test targets. Additionally, a wide choice of spring forces is available.
The ST-LPC1 series adds hardened steel tips which ensure an exceptional resistance to wear in high volume PCB test production runs. The LF-LPC1 series has hardened tips, extra-resilient plated
surfaces and an enhanced pre-loaded spring pressure to enable good penetration of the tough residual contamination often found on the surface of many lead-free solders.

How to use insulated head probes
Component Lead
Detection
It is often a requirement to provide a multi-purpose test onto
a single component or connector lead. The probes will fit into
standard ATE receptacles and require just one wire connection.
The insulated head probe will:
• Presence test the pin to check it’s set to the correct height
• Check whether the pin has passed through the hole
• Instigate an electrical test to ensure that the pin is
soldered properly to its pad, in combination with other
probes in the test fixture
• Fail any leads that have been bent over significantly.

Pass Marking Unit
The BMP-1 test pass marking unit is intended for installation into test fixtures and
production equipment. Upon receipt of test a pass signal it will rapidly scribe a permanent
circular mark onto the unit under test removing the risk of human error. This compact unit
requires a footprint of less than 15mm2 on the test board. The spring loaded carbide tip
is long lasting and its hardness will mark bare fibreglass (FR4), solder mask over glass
or copper, bare tinned copper, plastics and metal castings.
The unit is supplied with a mounting receptacle with knurled fitment, cables and a
plug/socket kit allowing easy connection to the jig’s internal wiring. The scriber can easily
be unscrewed from its receptacle so it can be transported for use in other positions. Extra
receptacles, an insertion tool and tip replacement parts are available as spares and these
are listed within the specifications.

Bench-top Test Jig
CMF series
Robust test jig using a cam-operated horizontal probe
plate. Ideal for self customisation.
The CMF series uses fixed position push fingers and is designed
to test low to medium density PCBs, such as those containing
conventional and surface mount circuitry.
Typical examples of their usage are:
Robust handle to operate
the cam system with an
interlock
• Repair and calibration stations
Cam operation ensures
a true linear motion of
the top plate
• Low to medium volume testing of PCBs - such as power supplies
and control boards
• Single or double-sided PCB probing
This series has a cam-operated G10 fibreglass push plate. When the lid
is latched closed the handle will then push down the upper plate, with
the provided pusher rods, ensuring a true linear downward motion onto
the PCB. Test probes can be fitted into both the base pan’s probe plate
and, to a limited extent, on the top plate allowing some double-sided
probing. The optional stripper plate supports the PCB and protects the
probe field.

High Current Test Probes
For load and functional testing of power components
This range of test probes can be used for load and functional testing of power components such as semi-conductors, solenoids, loaded PCBs, bus-bars, wound components and batteries. They
share identical dimensions and will readily intermix with the PA3, PA4 and PA5 series general purpose test probes. In particular, the HD-PA4 series is physically interchangeable with the PA4
series used in standard ATE test fixtures.

For load and functional testing of power
components such as bus-bars and batteries
Ultra High Current Test Probes
These series have an even higher current handling capacity than the other heavy duty (HD) ranges. By use of through-pin construction and a silver alloy contacting area, current flows of up to
400 amps can be passed. The probe bolts into the probe plate and will easily disassemble for cleaning. Uses for this range include load and functional testing of bus-bars and batteries.

Pneumatically Controlled Probing
Pneumatic test probes provide an alternative to the use of conventional spring contact test
probes to solve some problems in test fixture design. The major features of pneumatic
probing systems are:
• There is no need for a moving probe plate or push plate.
• The probes are held away from the test item until contact is required, which avoids
damage and wear and tear on the probe tips. When the compressed air is switched on
to the probe the tip moves into contact with the test pad.

An important consideration is that probes not in use are not in contact with the item under
test and so cannot introduce measurement errors by adding any erroneous circuit paths.
Below is a complete range of probes, together with all the hoses, terminations, manifolds
for air distribution, and electric switches for programming a test routine. Please note, this is

The top of the PAO barrel is flared making its design different to many probes. This allows a high density
of probes to be ‘pressed’ directly into the probe plate eliminating the need for a receptacle or gluing. This
‘press-fit’ feature also permits it to be installed in a variety of probe plate thicknesses. It can also be replaced
relatively easily.
PM1 and PM2, non-replaceable micro test probes
The non-replaceable micro test probes feature a collar at the top of the barrel, which is used as a stop in
the fitment process. Due to the minute barrel diameters and thin walls, it is imperative that the drilled hole
diameter and straightness are very accurate. We recommend that the pre-wired option is taken as connecting
a cable to these probes is an extremely delicate operation.
Usually, multi-plate fixtures containing no less than 3 plates, are used to retain large multiples of probes.
Otherwise a block of stable material which will allow reliable drilled holes is to be recommended, with the
microprobe fitted wire/tail first with tweezers, with a small amount of locking compound on the side to
secure it, if required.
The PAO is available with or without 30” of 30 AWG insulated wire attached. It is installed into the probe
plate with a probe insertion tool (part no. PITO) or a pair of tweezers. Shrink tubing can be used on alternate
probes to provide strain relief in the termination and to reduce the possibility of electrical shorting.
To replace the probe, the wire is cut at the termination and the probe is then pushed out of the probe plate.

Usually, multi-plate fixtures containing no less than 3 plates, are used to retain multiples of receptacles.
Otherwise a block of stable material which will allow reliable drilled holes is recommended, with the receptacle
fitted wire/tail first with tweezers. A small amount of locking compound may be required on the barrel to
secure it. Then the microprobe may be pushed into the receptacle, tail first, using the tweezers, making
sure light pressure is put onto the probe’s collar, not onto the fragile plunger.

Bladed Test Probes
Large Headed Test Probes
This series of test probes has a pinned plunger to stop tip rotation. This allows the
probes to access a connector in a slotted connector housing.
A series of test probes with unusually large tip diameters. For applications where a very
large head is required, for example where the contact target is ill-defined.

Pass Marking Unit
Example installation
The BMP-1 test pass marking unit is intended for installation into test fixtures and production equipment.
Upon receipt of a test pass signal it will rapidly scribe a permanent circular mark onto the unit under test
removing the risk of human error. This compact unit requires a footprint of less than 15mm square on the test
board. The spring loaded carbide tip is longlasting and its hardness will mark bare fibreglass (FR4), solder
mask over glass or copper, bare tinned copper, plastics and metal castings.
Typically 1.30
1.7 - 2.0
Warning: Adequate
thickness spacers
MUST be used to limit
board travel as shown.
Failure to use proper
spacers will allow
scriber to bottom out,
stalling the motor and
permanently
damaging the marker.
Spacer
Probe
Plate
The unit is supplied with a mounting receptacle with knurled fitment, cables and a plug/socket kit allowing
easy connection to the jig’s internal wiring. The scriber can easily be unscrewed from its receptacle so it can
be transported for use in other positions. Extra receptacles, an insertion tool and tip replacement parts are
available as spares and these are listed within the specifications.

The spring loaded contact consists of a gold plated tubular metal barrel,
spring and plunger as a one piece assembly. The tip of the spring
loaded plunger will provide a reliable electrical contact to the mating
surface, whose distance away or position may well be indeterminate.
The tip of the plunger will usually be rounded in shape (radius) which
will prevent damage or significant wear to the contact land.
Several fitment types are available including surface mount and press
fitment. Some series of the press fitment type are available with a
receptacle which allows the spring contact to be replaceable. One of our
series of surface mount spring contacts can be supplied moulded in an
array of up to 20 spring contacts.
Typically a mating contact land is used as the mating surface. These are
available as press fitment or solder-in.
