Plunger: BeCu orsteel, gold plated

Test probes worksas electrical interfaces between the test equipment and the circuit board undertest.

The constructionof PQL50:

The plunger ismade of BeCu or steel plated with gold to eliminate surface oxides and to lowerelectrical resistance.

Various probe tipstyles are adopted to suit any test requirement according to differentapplications.

Spring is constructedof music wire, plated with gold which prevents corrosion.

The barrel is madeof phosphor bronze, plated with gold. The interior of the barrel makes goodelectrical contact with the plunger and spring whereas the exterior of thebarrel makes good electrical contact with the receptacle.

HOW TO eliminatecontact problems caused by dirty probes

PreventiveMaintenance:  

Environment – reduceairborne contamination such as dust, clothing fibers or particles from anadjacent wave-solder machine 

PCB –keep printedcircuit boards as clean as possible

Dust Covers – putdust covers over idle fixtures

Air Filters –fixingan air filter in the release port 

ProbeCleaning: 

Gently brushingthe probe tips with a small brush with nylon or natural fiber bristles

ICT probes aremainly used for testing electronic products. Apart from PQL50, our factoryprovides a large number of other test pins applied to different fields. If youare interested, please feel free to browse our website (www. ) fordetailed specifications or contact me any time. Thanks a lot!
