ABSTRACT:
A tweezer probe comprises a pair of arms (10) each made of a multi-layer printed circuit board. The outer conductive layers (20,32) on each arm are etched to form a shield region (36) and a tip contact (34). The tip contacts (34) are connected to inner conductive layers (24,28) by through-hole plating, the inner layers being etched to form connector wires (40) extending along the length of the arms to a connector region where leads (8) are attached. The arms (10) are substantially rigidly mounted together, with an adjustment mechanism (14,72,74,76) being provided to alter the angle between the arms, the tips being moveable towards each other against the bias provided by the inherent resilience of the arms.
