CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
3 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
The primary function is to provide precise mechanical alignment for test probes, ensuring they contact the correct test points on the device under test with consistent positioning and perpendicularity across multiple test cycles.
Material selection affects electrical insulation (preventing short circuits), wear resistance (extending service life), thermal stability (maintaining dimensional accuracy), and mechanical properties (providing necessary rigidity while allowing probe movement).
Regular inspection for wear at guide holes, cleaning to remove debris, verification of dimensional accuracy, and replacement when hole tolerances exceed specifications or when surface damage affects probe alignment.
