Can general prototyping boards handle up to 4-5A in current?

    So I'm fairly certain breadboards cant handle 4 amps, and pcb is a bit too expensive for our budget (and not really necessary), but can basic prototyping boards handle this kind of current?

    something like this

    You can figure it out if you know the thickness of the copper plating (it's probably "1/2 ounce" or "1 ounce"). Here's an App Note that has a discussion starting on page 7 about the current handling capacility of PCB traces:
