Abstract
The present invention provides a head suspension assembly, which cantilevers a read/write magnetic transducer head adjacent the rotating surface of a disk in a disk drive, and the method of constructing the head suspension assembly using adhesives adhesive control and distribution features designed to improve both the performance characteristics and manufacturing yields of head suspension assemblies. Such adhesive control and distribution features in accord with the present invention may include through-hole features and component perimeter overlays that impede the flow of adhesive onto surfaces and component interfaces of the flex suspension assembly where the presence of such adhesives may degrade the suspension assembly's performance attributes.
Claims27
A flex suspension assembly comprising a loadbeam, a flexure, and an electrical interconnect, wherein said loadbeam and flexure are adhesively attached to each other and cooperate to define a loadbeam/flexure interface, and wherein said load beam includes flexure/loadbeam interface adhesive control features for controlling the flow of adhesive between said loadbeam and said flexure.
A flex suspension assembly comprising a loadbeam, a flexure, and an electrical interconnect, wherein said loadbeam and flexure are adhesively attached to each other and cooperate to define a loadbeam/flexure interface, and wherein said flexure includes flexure/interconnect interface adhesive control features for controlling the flow of adhesive between said flexure and said interconnect.
The assembly of claim 12 wherein said flexure includes a flexure arm region and wherein said adhesive control features comprise interconnect adhesive control features for controlling the flow of adhesive between adjacent surfaces of said interconnect and said flexure and to restrict the flow of adhesive into the flexure arm region during manufacture of said assembly.
