Can I use a PDF File to be used as a background and place data boxes on top?

I'm afraid you cannot use a PDF file as the background of your form, because a background can be set only with an image.

Can you please describe in more detail what you may be trying to achieve?

If it is to simply display a PDF file that you already have, you can use our PDF Embedder widget:

If it is something else instead, please describe what it is you may be trying to achieve in more details, and we'll be happy to look for ways how it could be accomplished. Thank you.
