Dear Vignesh, For balancing the copper, You can pour GND copper in the empty areas , if your design dont mind. Without GND connection also we can fill copper but have to make sure that it wont be an antenna.

Is there any standard methodology for balancing the copper etching? Any tech paper which explains how the copper balancing is done??
