Contactor sleeve assembly for a pick and place semiconductor device handler

A method for adjusting a relative position of a modified pick and place vacuum probe with respect to a top surface of a semiconductor device comprising the steps of:

• providing a test handler which includes an aluminum body contactor housing having a base member with a top and bottom surface;
• providing a threaded tapped hole extending from the top to the bottom surface of said base member of said aluminum body contactor housing, said threaded tapped hole located approximately at center of said base member;
• providing a flanged sleeve having a knurled flange and threaded outer body engaging the top surface of said threaded tapped hole of said base member, said flanged sleeve containing a hexagonal shaped hole formed longitudinally therethrough;
• providing a hexagonal shaped rod slideable in said matching hexagonal shaped hole of said flanged sleeve, said rod includes a hole extending longitudinally, from a proximal end to a distal end for communicating a vacuum, said rod further includes retaining ring grooves formed around the hexagonal surfaces near both ends of said rod;
• providing a first compression spring means inserted between the top surface of said base member and the bottom surface of said knurled flange of said flanged sleeve;
• providing a first c-clip retaining ring inserted in groove of said hexagonal shaped rod, said rod placed in flanged end of said hexagonal hole.
