Micro Test Probes

A range of micro test probes designed to allow very fine pitch testing of PCBs, substrates, semiconductors and devices, from 0.46mm to 0.76mm test centres. The PM1, PM2 and PA0 series, are of a non-replaceable design; the space saved by not having a receptacle allows testing to as small as 0.46mm centres. The fitment method is a delicate yet simple process and you can have the option of a pre-attached cable, allowing easier connection to the test jig. The PM2’R’, PM3 ’R’ & PA0’R’ series use a receptacle, giving the added advantage of probe replaceability, yet still allowing testing at a minimum spacing of 0.5mm. The receptacle has the convenient option of a pre-attached cable.

For the very fine pitch testing of semi-conductor devices and PCBs down to 0.46mm centres

PM1 Series Non-replaceable. No receptacle. 0.46mm test centres. Drill hole size - 0.27mm-0.28mm Specification Full travel 1.00mm Working travel 0.67mm Spring force at wkg travel 15g Current rating DC 1 Amp Minimum test centres 0.46mm   INSTALLATION The non-replaceable microprobes 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 (0.27mm - 0.28mm) & 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.

PM2 Series Non-replaceable. No receptacle. 0.51mm test centres. Drill hole size - 0.34mm to 0.36mm. Specification Full travel 2.00mm Working travel 1.33mm Spring force at wkg travel 48g Current rating DC 2 AmpS Minimum test centres 0.51mm INSTALLATION The non-replaceable microprobes feature a collar at the top of the barrel, which is used as a stop in the fitment process.

PM2 'R' Series Replaceable with receptacle. 0.51mm test centres Specification Full travel 2.00mm Working travel 1.33mm Spring force at wkg travel 48g Current rating DC 2 Amps Minimum test centres 0.51mm Assembly information Receptacles (shown at bottom of page) : Mounting hole size: 0.41/0.43mm. A 0.40mm drill is recommended Drill part no. DM2R INSTALLATION The receptacles of the replaceable microprobes feature a collar at the top of the tube, which is used as a stop in the fitment process. Due to the minute tube diameters and thin walls, it is imperative that the drilled hole diameter & straightness are very accurate. It is recommended that the pre-wired option is taken - as connecting a cable to these receptacles is an extremely delicate operation. 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 to be 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.

PM3 'R' Series Replaceable with receptacle. 0.64mm test centres Specification Full travel 1.91mm Working travel 1.27mm Spring force at wkg travel 30g Current rating DC 2 AmpS Minimum test centres 0.64mm Assembly information Receptacles (shown at bottom of page) : Mounting hole size: 0.52/0.55mm. A 0.52mm drill is most commonly used: Drill part no.

PA0 Series Non-replaceable. No receptacle. 0.64mm test centres Specification Full travel .075" (1.91mm) Working travel .050" (1.27mm) Spring force initial at wkg travel 0.39oz (11g) 1.39oz (39g) Current rating DC 2 Amps Minimum test centres .025" (.63mm) INSTALLATION 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 and can be replaced relatively easily. 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. View all products in this series
