What is a tungsten rod for the use of semiconductor?
A 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.
Use and application of probe pins
A probe pin is used as a part which connects electrically ATE of a probe card with a pad on semiconductor chips. The probe card is necessary for inspection process of semiconductor chip of wafer situation.
