摘要： A bond wire feed system has a wire tensioning unit with a chamber that has a wire inlet aperture and a wire outlet aperture. The wire inlet and outlet apertures have centers that are aligned with a central axis of the chamber. A clamp is positioned to receive a bond wire provided from the wire outlet aperture. The clamp has at least two jaws movable relative to each other and arranged to grip the wire to align a central axis of the wire with the central axis of the chamber. The jaws are also movable along the central axis of the wire in order to pull the wire through the wire tensioning unit.

摘要： A semiconductor die is packaged by providing a die assembly that includes a semiconductor die with an active surface and an opposite mounting surface with an attached thermally conductive substrate. The die assembly is mounted on a first surface of a lead frame die flag so that the thermally conductive substrate is sandwiched between the die flag and the semiconductor die. Bonding pads of the die are electrically connected with bond wires to lead frame lead fingers. A mold compound then encapsulates the semiconductor die, bond wires, and thermally conductive substrate. A second surface of the die flag is exposed through the mold compound.

摘要： A method of fabricating a perpendicular magnetic recording (PMR) head with a multi-level tapered write pole which creates an efficient channeling of magnetic flux to the pole tip. A tapered bottom yoke is first formed in an etched substrate and a write pole is formed on the tapered bottom yoke. The write pole comprises a main pole with a tapered tip. A tapered top yoke is then formed on the write pole and symmetrically positioned relative to the bottom yoke. The edge of each yoke is recessed from the ABS of the tapered tip, giving the write pole a stepped profile. The tapered tip can be two sloped surfaces that are symmetric about a mid-plane of the main pole or a single sloped edge on the leading side or the trailing side of the pole.

摘要： A perpendicular magnetic recording (PMR) head is fabricated with a multi-level tapered write pole. The write pole comprises a main pole with a tapered tip on a leading edge or a trailing edge, on which is formed at least one yoke that has a tapered edge. The edge of the yoke is recessed from the ABS of the main pole, giving the head a stepped profile. The yoke can be a single yoke formed on one side of the main pole or it can be two yokes formed on both the leading and trailing sides of the main pole. The write pole structure creates an efficient channeling of magnetic flux to the ABS surface of the pole tip which produces magnetic recording field at high area densities.
