Tungsten rod is a basic part for manufacture of a probe pin. It should not have defectiveness in straightness and in cut surface. A probe pine is the core part of a probe card which is inspection equipment. The probe pin is produced through chemical etching manufacturing process and mechanical manufacturing process. The probe card connects at the same time each signal wires of a tester with each pad of a wafer by chip unit so that a wafer tester can really test the function and capacity of a wafer.

 

Kind of Tungsten rod for semiconductor:

Raw tungsten + wire plated by Ni

Raw tungsten (Not plated by Ni)  

General tungsten + wire plated by Ni

Tungsten guide rods offer the ultimate in recoil reduction. Tungsten weighs more than double
