Abstract
A device for orienting an integrated lead suspension tail during a head gimbal assembly soldering operation of a head stack assembly process is disclosed. The device includes a body portion and at least one pin extending from the body portion. The pin(s) is configured to position the integrated lead suspension tail proximate to a main flex cable such that electrical coupling between the integrated lead suspension tail and the main flex cable is established upon completion of said head gimbal assembly soldering operation. The pin(s) has sufficient length to extend past a terminal end of the main flex cable.
Claims20
A device for orienting an integrated lead suspension tail during a head gimbal assembly soldering operation of a head stack assembly process, said device comprising:
- a body portion;
- and
- at least one pin extending from said body portion, said pin configured to position said integrated lead suspension tail proximate to a main flex cable such that electrical coupling between said integrated lead suspension tail and said main flex cable is established upon completion of said head gimbal assembly soldering operation, said at least one pin having sufficient length to extend past a terminal end of said main flex cable.
A method for establishing electrical coupling between an integrated lead suspension tail and a main flex cable during a head gimbal assembly soldering operation of a head stack assembly process, said method comprising:
- providing a body portion of an integrated lead suspension tail separator;
- and
- providing at least one pin extending from said body portion, said pin configured to orient said integrated lead suspension tail proximate to a main flex cable such that electrical coupling between said integrated lead suspension tail and said main flex cable is established upon completion of said head gimbal assembly soldering operation, said at least one pin having sufficient length to extend past a terminal end of said main flex cable.
A method for maintaining consistent gap widths between an electrical coupling of at least one integrated lead suspension tail of a head gimbal assembly and a main flex cable during a head stack assembly process, said method comprising:
- inserting at least one pin of an integrated lead suspension tail separator proximate to said at least one integrated lead suspension tail, said at least one pin inserted to a position below a first plurality of solder pads located on said at least one integrated lead suspension tail and a second plurality of solder pads located on said main flex cable, wherein said inserting causes said at least one integrated lead suspension tail to be inclined toward said main flex cable so that said first plurality of solder pads contact complementary ones of said second plurality of solder pads.
