Abstract
An electrically conductive grounding unit is situated between the integrated lead suspension and the tool block which is used to assemble it to the transducer head. The grounding unit grounds the uninsulated traces on the integrated lead suspension, thereby eliminating the danger of imparting static electricity to the transducer head during the assembly process. The grounding unit carries unwanted charges from the electrical traces on the suspension to the grounded tool block. The grounding unit is preferably fabricated from ceramic materials.

8. An apparatus for processing an integrated lead suspension having a suspension body and at least one integrated electrical lead extending across the suspension body for connection to a slider, comprising:
-
a base; an arm pivotally mounted to the base and having a platform on an upper surface for receiving the suspension body; a grounding body formed from an electrically conductive material and slidably mounted in a hole in the arm, the grounding body having an upper surface for contacting the integrated electrical lead above the platform while the suspension body is located on the platform, and a protrusion on a lower end for limiting upward movement of the grounding body through the hole in the arm; and a spring mounted to a lower surface of the arm adjacent to the hole in the arm for contacting a lower surface of the grounding body and urging the upper surface of the grounding body against the integrated electrical lead of the integrated lead suspension for protecting the slider against electrostatic discharge. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for processing an integrated lead suspension having a suspension body and at least one integrated electrical lead extending across the suspension body for connection to a slider, comprising:
-
(a) mounting the suspension body on an upper surface platform of a base; (b) contacting the integrated electrical lead above the platform with an upper surface of a grounding body which is slidably mounted in a hole in the base; (c) contacting a lower surface of the grounding body with a spring which is mounted to a lower surface of the base such that the upper surface of the grounding body is biased against and contacts the integrated electrical lead while the suspension body is mounted on the upper surface platform for protecting the slider against electrostatic discharge. - View Dependent Claims (15, 16)
