OPT8241-CDK-EVM: OPT8241-cdk evm evaluation board layout

Part Number: OPT8241-CDK-EVM

Hi,

We are designing our custom board mounting opt8241 and opt9221.

Our manufacturer told us that via type A, B,C in your .brd or drill file can't be realized due to very small outer ring copper around the drill.

He've suggested us a minimum drill of 6mils with 12 mils of pad. Your design with 6mils drill and 10 mils pad is impossible.

So how did you do that? Has the .brd been changed?
