Abstract: The present disclosure is generally related to a tape head assembly narrower than the width of a tape, wherein the tape head assembly comprises one or more heads, wherein each of the one or more heads comprise a curved surface comprising a first beveled wing, a second beveled wing, and a flat-lapped surface disposed between the first beveled wing and the second beveled wing. The first beveled wing and the second beveled wing each comprise outer corners recessed from a top surface of the flat-lapped surface such that there is no interaction between the outer corners of the beveled wings and the tape.

Abstract: In some examples, a method may include coupling a printed board assembly (PBA) to a fixture. In some examples, the PBA may include a printed board and a plurality of components that are electrically and mechanically coupled to the printed board, where each of the plurality of components defines a respective surface. The method may further include planarizing at least one of the respective surfaces of the plurality of components using an abrasive tool. The method may further include attaching a heat sink to the respective surfaces of the plurality of components. A system for planarizing surfaces of components attached to printed boards is also described.
