Materials

Receptacle: brass,gold plated

Contact barrel:phosphor bronze, gold plated

Spring: stainlesssteel wire or music wire, gold plated

Plunger: highcarbon steel (standard) or full-hard beryllium copper (available), gold platedover nickel

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

The constructionof P50:

The plunger ismade of high carbon steel or full-hard beryllium copper plated with gold to eliminatesurface oxides and to lower electrical resistance.

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

Spring is constructedof stainless steel wire or music wire, plated with gold which preventscorrosion.

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.

The receptacle ismade of brass plated with gold. Brass has features of high strength andhardness as well as resistance to chemical corrosion.

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
