I am trying to determine how large I can go for a new board design,
and am wondering what experiences some of you may have had.

The design will house fine pitch devices and a PBGA
1.6mm thick FR4
8/10 layers
Components are on both sides
P0.65mm/H0.3mm Vias and 0.2mm space/clearance
SMT reflow & most likely Wave for THT parts
Co-Planarity/Warpage kept to a minimum (This PCB will go into a
moving/hinged frame. I am looking to keep the flexibility of the PCB
to a minimum. There will also be a large number of wiring harness
connecting to the PWA)

Is anyone able to suggest what a reasonable limit is to aim for?

Regards,

Colin Weber
