Production Flash Connector X

The HDa12 is made in panels of the DCT4 panel-standard. This panel-standard has no space for Production Flash connections, so the Production Flash l/F is placed on the Phone itself.

The Production Flash-Connector includes the same connections as the Test Flash-Connector plus some more as described in table 4.

The Connector is made as eight Test Pads, which are accessible from the Keyboard-side of the PCB, only when the phone is without mechanical covers.
