Oh... an unpopulated physical board? Send it out to the manufacturer and they can give you a list of nets, based on the copper pads... but If its multilayer... you will have a real challenge on your hands deciphering it. I have had a machinist remove layers of the board to be able to see the connections on inner layers ... It's going to be expensive and tedious... Good luck... I don't envy you... Possibly you could get the board house to provide you with xrays of the board... that might help. Best regards, Bill Brooks - KG6VVP PCB Design Engineer , C.I.D.+, C.I.I.

I see now. Well... the only way thatI know of to get the netlist from this type of board is to take the board, an ohmmeter, a tablet of paper, and head off to the nearest coffee shop where I do a lot of 'beeping' work.
