  • Y-theta table for semiconductor equipment
    Patent number: 11121115
    Abstract: A positioning table, for example for a wire bonder has first and second arms, each of said first and second arms being independently drivable linearly along a first axis, and a stage that is engaged with both the first and second arms. The stage engages with each of the first and second arms via a respective engagement mechanism such that the stage is movable both linearly along the first axis, and rotatable about a rotary axis coincident with a center-point of the stage, the rotary axis being orthogonal to the first axis. Each engagement mechanism is configured to permit a respective distance between the center-point of the stage and an end of each of the first and second arms to vary during movement of an arm along the first axis.
