generic smd adapter/footp rints plus traces

I would like to create some footprints on small pcb rectangles that amount

to little more than generic smd adapters with a few extra traces and pads

for other parts.

These will be used for prototyping functional circuit blocks on copper clad

ground plane. The intent is to partially recreate something similar to the

Wainwright Systems MiniMount components. Some examples below.

sounds like you don't need a schematic at all.

In that case you can create your layout in the board editor alone.

Because these are not for specific parts, specific schematic symbols and

pin functions are not applicable. If I set pin parameters to nc, will that

affect connections on the schematic? Can all ic pins be set to passive or

does that apply to true passive components only? Any pitfalls to this

approach? Got a better idea?

Hi,

it's no problem to have all pins with direction like passive or i/o.

Eventually the pin direction affects the electrical rule check. Wih

pas or i/o you don't have too much messages about the pins.
