HMC1144 Pad dimensions

Hello, please, share the pad dimensions for HMC1144 (passivation opening that is). What is the die dimensions tolerance and thickness tolerance? Thank you.

    Hi Ivan,

    Here are the pad sizes in microns (width by height) with inches in brackets  beginning at pad 1 and going counter-clockwise around the die

    Pad 1 (RFIN):  53 x 119   (0.021 x 0.0047)

    Ground pads on either side of RFIN: 53 x 89 (0.0021 x 0.0035)

    There are 10 pads along the south side of the  die.  Moving from left to right the dimensions are:

    107x99 (0.0042x0.0039)

    107x99 (0.0042x0.0039) (Pad 12)

    99x99 (0.0039x0.0039)

    102x99 (0.0040x0.0039)

    99x99 (0.0039x0.0039)

    102x99 (0.0040x0.0039)

    99x99 (0.0039x0.0039)

    99x99 (0.0039x0.0039)

    99x99 (0.0039x0.0039)

    99x99 (0.0039x0.0039) (Pad 8)

    99x99 (0.0039x0.0039)

    Pad 7 (RFOUT) and the adjacent ground pads have the same dimensions as the RFIN pads

    If you go to the top of the die starting in the top left hand corner and move to the right, the dimensions are the same as the bottom pads. So the pad in the top left corner  (ground) is 107x99.

    The passivation is on a lower layer. So there is no encroachment of passivation over pad. So the "opening" is the pad size.

    The tolerance on the die's width and height is  +/-51 microns (+/-0.002)

    The tolerance on the die's height is  +/-10 microns (+/-0.00039)

    We will be updating  the die outline drawing to add these omissions.
