INSTALLATION NOTES:
Install these test-probes with either end toward the Device Under Test. The coil is offset toward the plunger end. The outer body compresses and an equal force is exerted by each end.
Install µHELIX® (without receptacles) in a probe-guide block with guide-holes on x,y coordinates corresponding to the DUT contact pad locations. Machine the block from a homogeneous, machinable plastic material such as UltemM®1000 (Polyeherimide), Techtron® (PPS), Ketron PEEK 1000, DELRIN® (Acetel), Torlon® 4203, Pomalux® (SD). Chemical, thermal, and electrical characteristics of these materials can be found in the Tech Note TN0019 or in from your plastic supplier's datasheets.
drill sizes probe-guide: #74; 572 µm (0.0225 inch)
plunger-guide: 1/64 inch; 397 µm (0.0156 inch)
i/o pin-guide: 1/64 inch or larger (function of fixture design)
guide hole depth probe body guide: 5500 µm
plunger-guide: Function of fixture design
i/o pin guide: Function of fixture desigh
Test-Probe Orientation: S500*5500-P2 Test-Probes can be installed with either end down
Test-Probe Removal/Replacement: Remove test-probes from the guide-block by first removing the i/o PCB or fixture 'Keeper' plate, then pushing test-probe Plunger(s) into the guide-block, and removing the test-probe(s) from the i/o end.
NOTE: Do not pull the plunger away from the guide-block nor attempt to pull the test probe out of the guide-block from the plunger end.
To clean guide-block (loaded or unloaded) submerse it in clean alcohol in an ultrasonic bath
Replace test-probes by loading them into the guide-block and reinstalling the i/o block or fixture 'keeper' plate.
