Hi, everyone, i’ve been studying a PCB design lately and i’m seeing this type of routing: trace initiating from a pad, to a via and back to the pad. What is the purpose of this, how does it contribute to efficiency?
And btw, if i try routing this way, when i draw the trace from the via back to the pad, the previous trace (from pad to via) disappears, as its trying to tell me: that’s the same path. How can i draw this without the previous one disappearing.
Below is the pic about the issue im talking about.
