Re: gEDA-user: Preliminary report on gerbers with buried, hidden and micro vias

[DJ Delorie <dj@xxxxxxxxxxx>]

A little googling found one fab house that did it differently :-P

+============]  [===]  [===  \

                    ]  [     <-- blank

+============]  [===]  [===  /

Then you can glue two of these together to make 8 layer boards.

Yet another etched matching copper on adjacent panels (i.e. as above
but no blank, resulting in 3 copper layers) and allowed vias between
any adjacent copper layers.

Sigh.
