Abstract:
Method of attaching to load beams flexure-bearing wireless conductors comprising a laminate of a plastic insulative layer and conductive traces, including (1) arranging at a laser welding station a first load beam fret comprising a first plurality of load beams at a predetermined fixed spacing, (2) juxtaposing with said load beam fret at the welding station a first plurality of wireless conductors carried unseparated in a wireless conductor pattern comprising within said station multiple pluralities of wireless conductors at a spacing that is a fraction of the fixed load beam fret spacing, (3) laser welding together said juxtaposed first pluralities of load beams and wireless conductors to form a first series of suspensions comprising a wireless conductor, a flexure and a load beam, (4) separating said wireless conductors from their pattern, (5) arranging at said laser welding station a second load beam fret comprising a second plurality of load beams at said predetermined fixed spacing, and (6) indexing said wireless conductor pattern within said station a distance less than said load beam predetermined spacing and corresponding to said spacing fraction and sufficient to register a second plurality of wireless conductors with said second plurality of load beams, and repeating steps (1) through (6) with additional frets of load beams until all wireless conductors of said wireless conductor pattern are welded to said load beams.
