6 Mounting other Fx3 devices on the board
Even though the AB-050-FX3-U is prepared for operation of the FK3 device also other devices of the Fx3-Line can
be mounted on the board.
Besides mounting the new device to the board
-
the components in the Pin Patch Area must be replaced according to the pin layout of the new device and
-
the signals between the device pins and the jumpers connecting the Electrical Area and the Functional
Area must wired manually.
Therefore the following changes must be applied:
6.1 Mounting
devices
First the device must be mounted to the PCB. The alignment of the different Fx3-family devices is explained below.
6.1.1 Mounting a FE3 device
To mount a FE3 device on the AB-050-FX3-U place the package in the lower left corner of the SMD area but do
not use the two pins most in the corner. Place pin 1 of the device on pin 2 of the SMD area.
