PCB Design: How to Have All Copper to be Tin/Solder Plated?

I need to have my PCB made in a such way that all copper, including pads and tracks, to be tin/solder plated. If I exclude the solder mask file from the Gerber file set that to be sent to a PCB house, will I get the PCB as I expected?

That is not a good idea. You might end up with a board totally covered in solder mask.

The safest way is to add a filled zone on the mask layer, covering the whole board.

Aha, that does the trick for me. THANKS!

You just need tell your factory that you do not need soldermask for this board.
