Use the following PCB guidelines:
- Verify the recommended PCB stackup in the PCB design guidelines, as well as the recommended layers for signals and ground.
- Ensure that the PCB footprint of the VQFN follows the information in .
- Ensure that the GND and solder paste of the VQFN PCB follow the recommendations provided in CC3120 and CC3220 SimpleLink™ Wi-Fi® and IoT Solution Layout Guidelines.
- Decoupling capacitors must be as close as possible to the VQFN device.
