Abstract
A framing assembly with lower stiffness design and a method of manufacturing that framing assembly are disclosed. In one embodiment, a framing assembly pattern is cut from a piece of a thin planar material, such as metal. The pattern is then bent to form a framing assembly with a base piece, two arms, and supports for a connection plate. In an alternate embodiment, the base piece includes a rear support and a support base. In a further embodiment, excess material surrounding the pattern is cut away so as to allow the most efficient use of the material.
Claims21
A framing assembly of a micro-actuator, comprising:
- a base piece molded from a single thin planar piece of material to be coupled to a head gimbal assembly;
- a first arm molded from the single thin planar piece of material bent perpendicular to a first side of the base piece;
- and
- a second arm molded from the single thin planar piece of material bent perpendicular to a second side of the base piece.
A system, comprising:
- a disk containing data;
- a head gimbal assembly with a suspension assembly;
- a magnetic read/write head to read the data from the disk;
- a printed circuit assembly to control the magnetic read/write head;
- a connection plate electrically coupling the magnetic read/write head to the printed circuit assembly;
- and
- a framing assembly molded from a single thin planar piece of material to connect the magnetic read/write head to the head gimbal assembly, wherein the framing assembly includes:
- a base piece to be coupled to the head gimbal assembly;
- a first arm bent perpendicular to a first side of the base;
- and
- a second arm bent perpendicular to a second side of the base.
A method, comprising:
- producing a framing assembly pattern for a micro-actuator from a thin planar piece of material, the framing assembly pattern including:
- a base piece to be coupled to the head gimbal assembly;
- a first arm;
- and
- a second arm;
- bending the first arm into a position perpendicular to the base piece;
- bending a first support into a position perpendicular to the first arm, the first support to be coupled to a connection plate to electrically couple a magnetic head to a printed circuit assembly;
- bending the second arm into a position perpendicular to the base piece;
- and
- bending a second support for the connection plate into a position perpendicular to the second arm.
