Abstract

Inspection windows are cut or formed into the tail section of the flexure circuit tail in a hard disk drive Head Gimbal Assembly (HGA), or CIS, to enable visual inspection of the alignment of the CIS to the head preamp circuit, or FPC. The holes are made in the steel backing and base polyimide, and are positioned between adjacent conductive pads. In addition to facilitating visual inspection, the windows also enable rework of solder. Additionally, solder wicking holes may also be provided in the conductive pads and/or the polyimide and steel backing.
