3.7 Handling (mounting the UNIGATE IC® on the carrier board)
Depending on the application and the expected shock- and vibration-conditions you can choose
from the following possibilities for the UNIGATE® IC's installation on the carrier board:
Mounting on a socket in the carrier board. If necessary solder the UNIGATE® IC to 2 or 4 pins
•
in the socket. Normally the IC can easily be pulled out after the soldering points have been re-
moved.
• Make arrangements for two holes next to the socket in the layout. After the UNIGATE® IC was
plugged in the socket pull an isolated wire over the IC and solder it on the carrier board at the
specified holes.
• Fasten the UNIGATE® IC With a wire or a tie wrap on the socket.
Manual soldering directly on the carrier board.
•
• Automatic soldering directly on the carrier board, whereas „selective" soldering is essential (no
wave soldering)
The advantage of the socketed variant is the easy download of Script- and Firmware-updates, if
the carrier board is not designed for it. Besides, that way the Fieldbus can be changed easily by
changing the UNIGATE® IC if the corresponding plug connectors are provided on the carrier
board. Another advantage is, that - normally - only a reflow soldering of the carrier board is ne-
cessary.
The advantage of the soldered variant is, that the installation height is lower and a higher shock-
and vibration-safety is provided.
