I am an amateur PCB designer. Trying to design my first PCB. It's a two layer board with ESP8266 module. I have read lot about ground plane and copper pour at the bottom layer. I have tried to use all those knowledge while designing this PCB. Can someone please tell me if I made any BIG mistake here? Here is an image of the bottom layer..

  • \$\begingroup\$ I'd consider flipping the Hi-Link Module, put AC on the edge of the board, and DC pins closer to the middle. Also check if the creepage distance/gaps are large enough for your voltage and PCB finish (mask or no mask, etc). Also, maybe some more margin around the antenna, since apparently you can afford it.. \$\endgroup\$ – Wesley Lee Apr 20 '18 at 8:42
  • \$\begingroup\$ Hi @WesleyLee Ohh sorry, that was an old gerber, I have already flipped it :) Let me change it.. I can also remove some copper beneath the atenna, no problem.. Beside these do you see any other major issue? \$\endgroup\$ – Rakesh Mehta Apr 20 '18 at 9:09

    \$\begingroup\$ What is connected to the relays? Mains voltage requires a minimum trace distance and your ground layer would make the design totally unsafe. \$\endgroup\$ – Oldfart Apr 20 '18 at 9:20
  • \$\begingroup\$ OMG, I totoally forgot AC on the relays.. Let me remove the copper there.. Thank you for reminding me.. \$\endgroup\$ – Rakesh Mehta Apr 21 '18 at 7:10

Welcome you to PCB!

It's not a problem. If there will be any island copper please delete that.
