With this being my first PCB, I wanted to know if it was standard practice to make the entire top signal layer into a ground plane solely for the two ground pads that I have for the audio connectors which pour into the plane?
I read that if there are a lot of traces, the ground plane can affect signal integrity, but in this case, I have very few traces.
Additionally, at the node where the traces split on the left 20 pin header, I have 5V splitting in parallel to supply 5V each for both audio jacks. Is this the correct way to maintain the parallel circuit?
I ask this because even though I had the parallel layout on the schematic. Altium's active routing created a trace from the pin to the first audio jack pad, then another trace from the first audio jack pad to the second audio jack pad. Is this not connected in series?
