Abstract
Described is a fixture for glass-bonding a digital magnetic recording slider workpiece (the component parts thereof), while holding them carefully aligned. In one preferred embodiment this fixture includes a slot for receiving a number of such work pieces in pre-assembled form registering and aligning them together and providing retainer means individually for each work piece adapted to resiliently and selectively engage each work piece and hold it positively in careful, precise alignment while glass-bonding and related operations carried out on the array of multiple work pieces so-aligned and retained.
Claims11
An improved method for retaining an array of tiny fragile workpieces in a common fixture during processing where each workpiece must be held therein by a fairly precise constant retention pressure, the method comprising:
- providing a workpiece-receiving channel in the fixture with a prescribed precision-oriented precisely flat registration surface along one side of the channel;
- and a precisely flat base surface orthogonal thereto;
- disposing each workpiece at a respective site along the base surface of the fixture channel;
- said fixture having retainer means for each workpiece at its site in the form of contact means resiliently applicable against the workpiece by associated lever means to press it against the registration side of the channel;
- clamping the workpieces in place with the contact means;
- conducting the treatment and releasing the workpieces for removal by actuation of the lever means.
An improved method of fashioning and glass bonding a plurality of slider assemblies, comprising:
- providing fixture means having a fixture slot means including a pair of orthogonal base and side surfaces which are precisely flat and carefully aligned;
- the slot means being adapted to form N sites along the base, each for receiving a respective slider assembly;
- also providing like retainer means for each site, being adapted to be selectively actuated into and out of resilient contact with the respective slider assembly;
- disposing each assembly in a respective one of said slot sites and retaining it in place with said associated retainer means;
- and then performing at least a glass bonding step while retained in said slot.
