PCB Layout Rules
This section provides general good practices in defining a PCB layout.
B.1 Placement
It is good to perform the placement of all the major components blocks before
routing any section of the PCB design. The considerations here are:
• CB410L module
•RF interface
•Reset circuit
Initial placement of these parts allows assessment of the PCB floor plan usage
and avoids any significant changes to final routed areas of the design if a
placement issue is found.
The following information presents considerations when performing this
placement:
1. Keep them in a similar quadrant to interface they connect to.
2. Consider orientation to avoid crossing traces when routing
3. Keep them as close as possible to the CB410L module where possible.
Note: You can consider keeping 4mm from the perimeter of the module
for component placement to allow possible update of alternative
Sequans' module solution.
