Abstract
A head suspension assembly includes a load beam having predefined gluing regions for gluing a bundle of wires thereto. For each gluing region, the load beam is partially-etched with the pattern that includes a plurality of grooves. Preferably, the pattern within the gluing region includes a set of parallel grooves. The gluing regions can be formed at very little cost because partial etching can be performed while simultaneously etching other features on the load beam. Advantageously, the gluing regions provide enhanced adhesion between the wires and the load beam which reduces the possibility of failure during manufacture, thereby reducing costs.
