PCB Layout Rules
This section provides general good practices in defining a PCB layout.
4.1 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:
• VZM20Q module
•RF interface
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. This also provides an opportunity for Sequans to
review the placement.
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 VZM20Q 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 such as US130Q.
