Abstract
A connector board which interfaces a disk drive head assembly to a test apparatus. The connector board is capable of being separated into segments which facilitate head assembly testing without changing connector boards, wherein test connections may be established supporting differing numbers of head assembly wires. By way of example, the connector board is adapted so that it may be used with either four-wire heads or two-wire heads, and further provides simplified separation should only a two-wire connection be required.
Claims19
In a connector board for interfacing a disk drive head with a test apparatus, said connector board having a first end, second end, right portion and left portion, the improvement comprising;
- (a) at least two spaced apart electrical conductors adapted for connection to a disk head and connected to
- (i) at least two corresponding spaced-apart insertion connectors adapted for connection to an insertion type connector and
- (ii) at least two corresponding conductor pads adapted for connection to a pin type connector;
- and
- (b) the connector board having a cutout, said cutout defining physical segments in said connector board and facilitating separation of said connector board, along at least one of a longitudinal axis between said ends and a center axis extending between said right and left portions of said connector board and perpendicular to the longitudinal axis, into at least two physically and electrically isolated connector board segments, at least one said segment for connecting a read element of said disk head to said test apparatus and at least one said segment for connecting a write element of said disk head to said test apparatus.
