Although the term board is used to refer to printed circuit boards, generally this tag is used instead of pcb when it's related to the identification or operation of some existing board or details on specific boards, while pcb is used molstly regarding design and fabrication. Note that these are not rules, but it is how the terms are mostly used.

What is this waxy stuff?
I just opened up an old piece of electronics. While salvaging, I found a board with this waxy stuff on it? What is this and what is its use?
P.S. The substance I am talking about is the lightly tanned wax on the top right of the board.
