Latest Patents
One of Richard Wahl's latest patents is the Dual-mode Z-stage. This innovative device supports and moves workpieces, such as semiconductor wafers, into position for testing. The Z/Theta stage features a peripheral four-point elevator drive, which utilizes parallel, vertically oriented, rigid lift pins to bear the weight of a top plate. This design minimizes frictional forces, allowing for smoother operation. The lift pins are elevated by matched pin lift levers driven by a vertically translating air piston, providing a gentle force moderated by pneumatic pressure.
Another significant patent is the contact probe assembly having rotatable contacting probe elements. This electrical probe assembly includes elongated probe elements made of conductive flexible material. These elements are designed to establish electrical contact with pad surfaces. The assembly maintains the probe elements in a generally parallel arrangement, allowing for simultaneous rotation to enhance contact efficiency.
