Abstract
A method is disclosed for curing epoxy adhesive between the slider head and load/gimbal suspension assemblies of a disk drive access actuator employing a concentrated pulsed heat source rather than conventional, broadly applied heat source as employed in the past, such as oven heating or UV exposure. The laser source power is delivered via an optical fiber to the slider air-bearing surface (ABS) of the slider head assembly so that with this approach, the time for curing can be minimized and accurately controlled without causing damage to the assembly, and the overall curing step in the manufacturing process is reduced in time of application. Apparatus in the form of a fixture, such as an anvil element, provides a convenient gauge and support for alignment of the laser output beam with the slider ABS to which the heat for curing is to be applied as well as provide for its heat sinking.
