7. Mounting
CBM-003B/C has two sets of soldering pads, which
allow it to be mounted both in horizontal and vertical
position. Inn vertical position module can be installed
either by to a 1,27 mm pitch 2-row pin header, or by
soldering the module directly into a routed slot on the
main PCB.
When mounted in horizontal position there will have to
be two keep-out areas; one for the antenna area and
one for the unused pads used for vertical assembly.
7.1 Horizontal mounting
When CBM-002B/C is mounted in a horizontal position
it is soldered in by using the soldering pads on both
long sides of the module. The soldering pads are
designed so that the module can be both hand and
reflow soldered.
When mounted in a horizontal position, there are two
mandatory keep-out areas involved. One is for antenna
and the other is for bottom side soldering pads at the
narrow end of the module. These pads are used for
vertical assembly.
For the CBM-003B, the antenna keep-out applies to
all layers of the mother board. There shall not be any
components, traces, pads or copper areas in any layer
within the keep-out area. The same applies to other
metals as well, such as the enclosure of the product,
fixing screws, etc.
The keep-out area for the soldering pads applies only
to the outer surface of the mother board.
Recommended land pattern for horizontal assembly and required keep-out areas.
1) This keep-out area will have to be kept clear from any parts, traces and copper on all layers.
2) This keep-out area applies only to the layer closest to the module.
3) If CBM-003C antenna is soldered vertically, this keep-out area will have to be a hole.
Otherwise keep-out area applies only to the layer closest to the module.
