Abstract
In a disk drive, an interconnect adapter for coupling a head of a suspension assembly to front-end read/write circuitry includes a pad set with a plurality of specially designed pads. The pads are formed with an integrated frame and multiple tabs. The tabs enable removal and replacement of the pad set from the suspension assembly to enable suspension assembly rework. The interconnect adapter is designed to adapt to polarity specifications of various head and read/write circuitry designs. The pad set design is configured for connection with a variety of traces, with a piezoelectric microactuator, pre-amplification circuitry, and any of a variety of heads.
Claims20
A suspension assembly having an interconnect adapter for removably coupling the suspension assembly with read/write circuitry comprising:
- a suspension assembly having a load beam, a head assembly attached to the load beam and traces extending from the head assembly, the traces defining termination pads;
- and
- an interconnect adapter having a first end connectable with the termination pads and a second end connectable with the read/write circuitry, the first end of the interconnect adapter having a pad set with a plurality of pads, each pad having a frame and tabs, each tab being connectable to the termination pad;
- wherein the tabs are individually severable from the frame to enable removal of the interconnect adapter from the termination pads.
A suspension assembly as set forth in claim 3, wherein jumpers interconnect to the frames of the functional pads and the dummy pads.
An interconnect adapter having a removable test pad and being removably attachable to a suspension assembly comprising:
- a first end having a pad set, the pad set having a plurality of pads, each pad defining a frame and tabs extending from the frame;
- wherein the tabs are individually severable from the frame to facilitate removal of the interconnect adapter from the suspension assembly;
- a second end having a test pad to enable the interconnect adapter to be tested;
- and
- a detach line defined between the first end and second end to enable removal of the test pad.
A suspension assembly having an interconnect adapter for removably coupling the suspension assembly to read/write circuitry comprising:
- a load beam;
- a head assembly attached to the load beam;
- traces extending from the head assembly defining termination pads;
- an interconnect adapter having a first end connectable with the termination pads and a second end connectable with the read/write circuitry;
- the first end of the interconnect adapter having a pad set with a plurality of pads, each pad having a frame and tabs, each tab being connectable to the termination pad;
- wherein the tabs are individually severable from the termination pads to enable removal of the interconnect adapter from the termination pads;
- and
- the second end of the interconnect adapter having a pad set with a plurality of pads, each pad having a frame and tabs, and the tabs are individually severable.
