Abstract
A high density slider clamp fixture is disclosed for accurately positioning a large number of head sliders for metrology testing. The slider clamp fixture may include a single piece, monolithic structure comprising a large number of slider nests, aligned in rows and columns in the slider fixture. Each slider nest includes a reference datum surface machined to precisely align with all other reference datum surfaces in a row of the monolithic structure. Each slider nest further includes a flexure clamp for independent clamping of each slider in the row against the reference datum surfaces.
Claims20
A method of fabricating a clamp fixture for aligning a plurality of sliders in one or more rows against one or more reference datums, comprising:
- (a) machining a monolithic structure in a first direction to define a reference datum in each row of the one or more rows, and to form a pair of gaps defining individual flexures in each row of the one or more rows for independently clamping sliders against the reference datum in each row;
- and
- (b) machining the monolithic structure in a second direction, orthogonal to the first direction, to in part define the individual flexures in each row.
A method of fabricating a clamp fixture for aligning a plurality of sliders in one or more rows against one or more reference datums, comprising:
- (a) machining a monolithic structure in a first direction to define a reference datum in each row of the one or more rows, and to define individual flexures in each row of the one or more rows for independently clamping sliders against the reference datum in each row;
- (b) machining the monolithic structure in a second direction, orthogonal to the first direction, to in part define the individual flexures in each row;
- and
- (c) machining a non-circular opening through the clamp fixture in the first direction, the non-circular opening configured to receive a non-circular cam shaft for opening each flexure in a row.
A method of fabricating a clamp fixture for aligning a plurality of sliders in one or more rows against one or more reference datums, comprising:
- (a) machining a monolithic structure in a first direction to define a reference datum in each row of the one or more rows, and to define individual flexures in each row of the one or more rows for independently clamping sliders against the reference datum in each row;
- (b) machining the monolithic structure in a second direction, orthogonal to the first direction, to in part define the individual flexures and slider nests in each row, wherein all flexures in a row have a reference edge clamped against the reference datum in each slider nest when the flexure is in a closed position.
