Hi! Michael:
Thank you for your suggestion. It seems that copper fill that you and
several other guys mentioned does not applied in my board. For external
layers, you can implement the copper ring or, as other people suggested,
using copper fill but grounded it. In my case, I have a high-layer
Hi! Dan:
I understand that EMC guys don't want to see the floating coppers on the PCB
because of ESD and/or emission problem. But on the manufacture side, they claim
that if you don't do copper balance on the layer where you have large area
without copper, you will sure have over-eching in that
way as thieving copper above.)
