Receptacle Test Probe
Test probes - test pins - spring probes - pogo pins; these are all generic terms to describe a component whose spring loaded tip willprovide a reliable electrical contact to a target whose distance away may well be indeterminate. The traditional use for them is tomake contact with printed circuit boards (PCBs) or electrical components, in order to test functionality and to measure the value ofthe components. They are widely used in vacuum test fixtures associated with automatic test equipment (ATE). They are also usedinside 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 isgenerally connected to a receptacle which the test probe inserts into. The use of a receptacle allows the test probe to be removedfor cleaning or replacement without having to dissconnect the electrical cable (see illustration below).
The illustration opposite shows a test probe and itsreceptacle mounted in a block with the electricalconnection made to the tail of the receptacle. Thereceptacle has been inserted using a receptacleinsertion tool. Finally the cable is soldered to thetermination and the probe installed.

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 illustrateswhich 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 withlarge 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 areplaceable item as the electrical cable is connected to the tail of the receptacle. There are several versions of receptacle (see below) depending on your preferredchoice of cable termination - providing it is available in the specific probe series.

Fitment and usage
After care
A regular maintenance programme for your probes will help you achieve themaximum probe performance and lifespan. The necessary frequency andmethod of the maintenance/cleaning programme depends on your productionenvironment, the type of equipment and the probe series used.
Contamination left behind on the probe tip is the primary cause of probe contactproblems. This is often caused by a bi-product of the soldering process of eithersoldering flux or a solder residue. Other local contaminants such as dust, fluff,oil and grime can cause more temporary problems.
Light brushing of the probe tip with nylon, bristle or soft metal brushes willdislodge most contaminants.

Example fitment methods are shown for each series in the General Purpose TestProbe section starting overleaf. The receptacle is usually mounted into a probeplate. This plate can be made of resin-laminated fibreglass (types such as G10 orFR4), or plastic materials such as nylon, perspex or polycarbonate. The thicknessshould be such that it will support the total spring pressure of all probes without itbending significantly. For very large arrays of probes it may be necessary to putsome support pillars underneath to minimise this problem. For general purposetest applications, an 8-10mm thickness of material is recommended.
Carbide drills are best suited for drilling holes for receptacles in the hardercomposite or fibre based materials. Commonly available high-speed drills (HSS) aresuitable for plastics, such as peek, nylon or perspex. A few sizes of carbide drillshave an option of longer flute length for thicker probe plate materials. Note: Where two drilled hole sizes are shown, the larger hole is for harder materials such
as FR4, G10 and Tufnell, and the smaller hole is for plastics.
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.
3. Inserting the probeRemove the tool and insert the probe rearwards and
press home. The probe’s body isnormally fully enclosed withinthe receptacle.
4. Cable attachmentAttach the cable to the back endof the receptacle.

1. Inserting the receptacleThe receptacle may be flushmounted or set raised slightlyabove the probe. In most generalpurpose test situations thereceptacle height is set to flush.
The receptacle should slip downunassisted until the press-ringrests against the probe plate.
2. Using a receptacle insertion toolReceptacle insertion tools are required for inserting the receptacle’s press-ring into thehole without damaging it (see table above for tool selection). This is particularilyimportant if you are using harder materials for the probe plate. Insert the pin of the
tool into the receptacle and tap the insertion tool gentlywith a hammer, until the receptacle is set to the desiredheight. See box 2a for instructions using epoxy fitment.
2a. Using epoxyIt is perfectly acceptable to use the press-ring asa shoulder to stop the receptacle from pushinginto the hole. However, you will have to bondthe receptacle in place using a suitable epoxy.We also offer receptacles with stop rings to allowflush mounting with epoxy.

How to use ATE TesProduct selection
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, withouthaving to disconnect the electrical cable. There are several versions of receptacle (see below) depending on your preferred choice of cable termination - providingit is available in the specific probe series.
• Clean leads, pins• Clean terminal pins
• PCB lands• PCB pads

ATE probe tip selectionThere are three sizes of ATE test probes for the three standard test centrespacings (pitch) commonly used on printed circuit boards (PCBs). See previouspage. Once you have selected the probe size which will best suit your applicationyou will need to select suitable tip styles. The table below shows which of thetip styles is likely to be most effective for each particular test target.
Spring pressureMost series have a wide choice of spring pressure. A lighter spring is preferredin test applications where the test point is fairly clean or uncontaminated. Theheavier and extra heavy springs will help the probe tip to penetrate betterthrough any contamination. A lighter spring may have to be a consideration intest fixtures with large quantities of probes, or in situations where the densityof 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
can handle, or may damage your PCBs top layer. It is better to target the extra-heavy spring forces in known problem areas.
Plunger material and lead-free solderThree choices of plunger and tip material are available depending on thevolume of the production run and the level of PCB contamination. See below:

st Probes and ReceptaclesFitment and usage
After care
The receptacle is usually mounted into a probe plate. This plate canbe 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 drillbits are required to drill holes in this material. The thickness of theprobe plate should be such that it will support the total springpressure of all probes without it bending significantly. For very largearrays of probes it may be necessary to put some support pillarsunderneath to minimise this problem. For general purpose testapplications, an 8-10mm thickness of material is recommended.
A regular maintenance programme for your probes will help you achieve themaximum probe performance and lifespan. The necessary frequency andmethod of the maintenance/cleaning programme depends on your productionenvironment, the type of equipment and the probe series used.
Contamination left behind on the probe tip is the primary cause of probe contactproblems. This is often caused by a bi-product of the soldering process of eithersoldering flux or a solder residue. Other local contaminants such as dust, fluff,oil and grime can cause more temporary problems.
Light brushing of the probe tip with nylon, bristle or soft metal brushes willdislodge most contaminants.

Notes: To replace an existing receptacle, either broken or wrongly set, you can use our receptacle removal kits. See page 15.
1. Inserting the receptacleThe receptacle may be flush mounted, orset raised slightly above the probe plate.In most ATE situations the receptacle’sheight is set raised. The receptacle shouldslip down unassisted until thepress-ring rests against theprobe plate.
2. Using a receptacle insertion toolInsert the pin of the tool into the receptacle (you will need to set the height required on theadjustable tool). Tap the end of the tool with several light taps until the receptacle is set to therequired height. See the table above for tool selection.
3. Inserting the probeRemove the tool and insert the probe rearwards and press home with a probe insertiontool (see above). The probe’s body is normally fully enclosed within the receptacle.
4. Wire attachementAttach the cable to the backend of the receptacle.
Notes: Where two drilled hole sizes are shown, the larger hole is for harder materials such as FR4, G10 andTufnell, and the smaller hole is for plastics.

The PA4 series is the universal size for use at 2.54mm test centres in the majority of ATE test fixtures. It has a very widerange of tip styles for almost all test targets. Additionally, a wide choice of spring forces is available. The ST-PA4 series
adds hardened steel tips which ensure an exceptional resistance to wear in high volume PCB test production runs. The LF-PA4 series has hardened tips, extra-resilient plated surfaces and anenhanced pre-loaded spring pressure, to enable good penetration of the tough residual contamination often found on the surface of many lead-free solders.

Insulated head probes are used for circuit board component lead detectionand testing. The insulating shroud is raised slightly higher than the metal
serrated tip. During test, if the component lead or connector pin is set correctly, the electricalcontact will be made. Pins absent or misaligned will cause the shroud to make contact first andfail the test.
A useful series of devices for measuring the travel at any probeposition in a test fixture. After the PCB is fully down onto the probe
field, the indicator probes remain compressed. The change in length indicates the travel.
Do not insert into the receptacle by pressing on the plunger!

How to use insulated head probesIt is often a requirement to provide a multi-purpose test ontoa single component or connector lead. The probes will fit intostandard 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 otherprobes in the test fixture
• Fail any leads that have been bent over significantly.Reason for failure:Pin set incorrectly
Reason for failure:Pin missing

Receptacle insertion tools arerequired for inserting the ATEreceptacle into the hole withoutdamage to the tube, particularly ifyou are using harder materials forthe probe plate. With a correctly sized drilled hole,the receptacle should slideunassisted down to the press-ring. The insertion tool will takeover the insertion from here. In most ATE applications the receptacle’s height is usuallyset as raised, so we supply adjustable height receptacle tools for inserting them. See the‘How to fit’ box for more information - page 11.

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

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 to400 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.

Pneumatic test probes provide an alternative to the use of conventional spring contact testprobes to solve some problems in test fixture design. The major features of pneumaticprobing 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 onto the probe the tip moves into contact with the test pad.
• The ability to program sequential tests using a programmer and electric valves tooperate different probes at set times in the test program.
An important consideration is that probes not in use are not in contact with the item undertest 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, manifoldsfor air distribution, and electric switches for programming a test routine. Please note, this isa hypothetical set up to show all the components in use.

PM1 and PM2, non-replaceable micro test probesThe non-replaceable micro test probes feature a collar at the top of the barrel, which is used as a stop inthe fitment process. Due to the minute barrel diameters and thin walls, it is imperative that the drilled holediameter and straightness are very accurate. We recommend that the pre-wired option is taken as connectinga 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 themicroprobe fitted wire/tail first with tweezers, with a small amount of locking compound on the side tosecure it, if required.
Installation
PA0, non-replaceable micro test probes
The top of the PAO barrel is flared making its design different to many probes. This allows a high densityof 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 replacedrelatively easily.
The PAO is available with or without 30” of 30 AWG insulated wire attached. It is installed into the probeplate with a probe insertion tool (part no. PITO) or a pair of tweezers. Shrink tubing can be used on alternateprobes 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 receptaclefitted wire/tail first with tweezers. A small amount of locking compound may be required on the barrel tosecure it. Then the microprobe may be pushed into the receptacle, tail first, using the tweezers, makingsure light pressure is put onto the probe’s collar, not onto the fragile plunger.

Presence Detection Switching Probes
Insulated head probes are used for circuit board component lead detection andtesting. The insulating shroud is raised slightly higher than the metal serrated
tip. During test, if the component lead orconnector pin is set correctly, the electrical contactwill be made. Pins absent or misaligned willcause the shroud to make contact first and failthe test.

How to use insulated head probesIt is often a requirement to provide a multi-purpose testonto a single component or connector lead. The probeswill fit into standard ATE receptacles and require just onewire connection. The insulated head probe will:• Presence test the pin to check that it is 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 withother probes in the test fixture
• Fail any leads that have been bent oversignificantly.
Reason for failure:Pin set incorrectly
Reason for failure:Pin missing

PASS MARKING UNIT
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 testremoving the risk of human error. This compact unit requires a footprint of less than 15mm square on the testboard. The spring loaded carbide tip is longlasting and its hardness will mark bare fibreglass (FR4), soldermask 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 allowingeasy connection to the jig’s internal wiring. The scriber can easily be unscrewed from its receptacle so it canbe transported for use in other positions. Extra receptacles, an insertion tool and tip replacement parts areavailable as spares and these are listed within the specifications.

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