Abstract:
An apparatus used as a component of a die bonder for placing a semiconductor chip on a substrate, comprising:a first pivoted lever seated at one end on a first shaft, said first shaft mounted equidistantly between a first location and a second location, said first pivoted lever having a second shaft seated at another end;a drive coupled to said first shaft for pivoting said first pivoted lever in alternating pivoting directions through an angle of pivoting between a first end position in which said first pivoted lever is directed toward said first location and a second end position in which said first pivoted lever is directed toward said second location;a second pivoted lever having a same length as said first pivoted lever, a sum of lengths of said first and second levers equaling a distance from said first shaft to said first location or said second location, said second pivoted lever seated at one end on said second shaft, said second pivoted lever further having an axle seated at another end;a drive mechanism coupled to said second pivoted lever for rotating said second pivoted lever in an opposite pivoting direction with respect to said first pivoted lever;a slide seated on said axle which glides linearly between said first and second locations along a linear guide member; anda semiconductor chip gripper coupled to said slide which glides linearly between said first and second locations in correspondence with said slide.
