    Abstract: This application discloses a hard disk drive, a head stack assembly, and a printed circuit board configured to include impedance patches on the flex ground plane, the flex power plane, the printed circuit ground plane and/or the printed circuit power plane over or under a connector site in the disk base that conveys access read and write differential signals for the sliders' access of rotating disk surfaces. These impedance patches minimize impedance discontinuities in the read and/or write differential signals through the connector site, which may improve the ability of the hard disk drive to transmit these signals at higher frequencies.

    Abstract: A flexible printed circuit board (FPCB) includes a signal layer, upper and lower ground layers, and two dielectric layers. The signal layer includes a differential pair comprising two transmission lines to transmit a pair of differential signals. The dielectric layers are located on and under the signal layer to sandwich the signal layer. The upper ground layer is attached to the dielectric layer on the signal layer, opposite to the signal layer. The lower ground layer is attached to the dielectric layer under the signal layer, opposite to the signal layer. Each ground layer includes a grounded sheet made of conductive material. Two voids are defined in each ground layer and located at opposite sides of the corresponding grounded sheet. Distances between the middle line of the grounded sheet of each ground layer and middle lines of the two transmission lines are equal.

    Abstract: A connection device for high frequency signals includes a printed circuit on one external face of which is printed a transmission line and a coaxial connector surface mounted on the printed circuit on the external face. The invention is of particular use for the transmission of radiofrequency signals in the X band, in particular for frequencies from 9 to 10 GHz. The transmission line is connected to the connector by means of a bump contact belonging to the transmission line to which is attached a central core of the connector. The printed circuit comprises at least one internal ground plane parallel to the external face and contributing to the matching of the transmission line. The invention aims to improve the transparency of the transition between the connector and the transmission line. According to the invention, the internal ground plane is perforated by means of a resist facing the bump contact.
