Mounting BC40M and BC40C on the Host PCB
The following figure shows recommended mounting of BC40M module on the host PCB.
•
For the best Bluetooth range performance, the antenna area of module shall extend 4.4 mm outside the
edge of host PCB board, or 4.4 mm outside the edge of a ground plane.
•
The next choice is to place a module on a corner of host PCB, the antenna area shall extend 4.4 mm from
the edge of ground plane. Ground plane shall be at least 5 mm from the edge of the antenna area of
module.
•
We don’t recommend mounting BC40M module in the middle of a host PCB.
The
following figure shows recommended mounting of BC40C module on the host PCB.
•
For the best Bluetooth range performance, the antenna area of module shall extend 3.2 mm outside the
edge of host PCB board, or 3.2 mm outside the edge of a ground plane.
•
The next choice is to place a module on a corner of host PCB, the antenna area shall extend 3.2 mm from
the edge of ground plane. Ground plane shall be at least 5 mm from the edge of the antenna area of
module.
•
We don’t recommend mounting BC40C module in the middle of a host PCB.
BC40P shall be mounted near the external connector for an antenna.
For the best Bluetooth range performance, keep all external metal at least 30mm from the antenna area.
