Hello,

Have question on ground plane. In my design I need to plug in four different power sources ( 5V, 12 V, 15V and 40V). and there are capacitors which are connected to the 15 V. I understand "ground " means having a reference voltage level. Can any one suggest how to design ground plane when board gets power from multiple sources. Any help is appreciated.



Thanks,

ignore me - i have only read some PCB design related pdf-s coz they contained other stuff i was interested about . . .
-----------
  • your difficulty level
    (in a short form)
    • describe what's hooked to those voltages
      (in a sense of)
    • "device name" --or-- required power @ frequency

Are all the grounds common? Are any of these voltages high power?

You have provided woefully insufficient details on your circuit for any useful help. Post your schematic and any board layout you have so far.
