Without power and ground planes, the power distribution network of a circuit board can become quite noisy due to insufficient decoupling. For some designs this does not matter much. But my design includes circuitry for wireless RF communication and other sensitive analog circuitry and I would like to know if it is a bad idea to use a 2-layer board.
Board contains: AC-DC switching power supply (discrete), PIC microcontroller, PIR sensor (analog), thermistor (analog), relay, rf transceiver, antenna.
Board size does not allow for ground plane or power plane of any kind. Power and ground must be run from point to point.
Thanks,
Jeremy
