  • Needle with rounded edge
    Patent number: 11020108
    Abstract: A chemically etched needle is provided herein. The chemically etched needle includes a metal base having a first side and a second side. The chemically etched needle also includes a chemically etched blade at one end of the metal base and formed at an intersection of a distal diverging surface and a proximal diverging surface, at least one of the diverging surfaces slopes inward towards the second side.

  • Method and apparatus for detaching a head suspension component from a semi-finished suspension product
    Patent number: 8634164
    Abstract: A method of detaching a head suspension component from a locating and transport structure where the head suspension component is integrally connected to the locating and transport structure by a tab having a reduced tensile strength with respect to each of the head suspension component and the locating and transport structure. The method includes applying a tensile load to the tab to cause the tab to fracture, so that the head suspension component is detached from the locating and transport structure.

  • Full-rail suspension with shearing fracture detab
    Patent number: 8146233
    Abstract: A multi-piece head suspension assembly is manufactured from a semi-finished suspension product. The semi-finished suspension product includes a load beam having two side edges, a distal end, and a proximal end opposite the distal end. The semi-finished suspension product also includes a beam carrier strip connected to the proximal end by one or more tabs. Each tab includes a detaching region that has a lower shear strength than other regions of the tab. Rails are formed on the side edges of the load beam, and the semi-finished suspension product is attached to a hinge assembly at the proximal end of the load beam. A shear load is applied to the one or more tabs to cause the one or more tabs to fracture at the detaching region.
