Tungsten rhenium is most widely used in probe needle. Within the past two years, the use of tungsten-rhenium probe needles in the construction of probe cards has greatly increased. Traditionally, tungsten (W) probes were used for many reasons—excellent stiffness, hardness and wear characteristics.
Tungsten rhenium probe needles are fabricated from precision-straightened W and Wren fine-diameter wire. Wire drawing is accomplished by pulling and annealing swaged rods through incrementally smaller dies. As the wire cross-sectional area is reduced, the dislocations per unit area are increased, dislocation motion is hindered, and the material is considerably cold-worked. As a result, the strength and hardness values are systematically increased.
Advanced probing system is the world leader in tungsten rhenium probe needle production for probe card and wafer test applications. APS (American Physical Society) produces cantilevered and vertical probes in tungsten, tungsten rhenium, beryllium copper, and network. APS also provides enhancements including bent probes and insulation
