Test probes

Feinmetall’s assortment of test probes includes contact probes for automatic pick-and-place assembly of printed circuit boards (PCB) or other electronic devices. These solderable, short travel parts are available as taped components for fast and cost effective mounting interrupting a manufacturing process. The company has also developed a special series of spring contact probes for difficult conditions eg, for lead-free soldered PCBs.

For high-current contacting of blade connectors, a probe is available with a slotted contact head that is moved over the contact blade. The compression of the plunger leads to a twisting motion that ensures the contact head makes solid, smooth contact with the test item without damaging or scratching the surface.

To accommodate precise resistance measurements with small centres or limited space, a coaxial Kelvin probe has been developed that can be used for centres down to 2,2 mm.
