Very important. Once the signal gets into the ground plane from the circuit, there will be a ripple. Ripple may spread and influence the signal in other circuits.
If we don’t have a ground plane, the ripple will last longer and may influence other circuits nearby.

I am a project procurement a for telecom device. When I compared the unit price of the same IC between Digikey and Alibaba and find Digikey one is much more expensive. Why?
We would like to assembly the smart chip by ourselves because and then ensure the wifi pairing. Any cautions when we place the order to factory to assembly extra part?
There is a copper pour over the entire top of the my PCB, which is part of GND net. It turns out that the surface mounted 1W LEDs I’m going to use have the heat slug connected internally to the LED’s +ve terminal. Can I rely on the solder mask to insulate the +ve voltage (~3V ish) from GND? Long term?
The space of printed circuit boards (PCBs) is often at a premium in modern, compact product designs, optimizing PCB size has become an essential consideration.
Have you ever opened up the case of a broken smartphone or smartwatch? If yes, you will be familiar with small circuits packed into such
A common question when designing complex printed circuit boards for advanced electronics is whether to use stacked or staggered vias to route connections between layers.
