A circuit board panel (100) having first and second sides (231, 213) includes opposing score-lines (105, 215) defining a boundary between a first and a second circuit board portions (101, 103), and provide a break line for fragmentation of individual printed circuit boards from the circuit board panel. The circuit board panel includes a pair of electrical test pads (107, 108) which are electrically connected to electrical runners (225, 217). Testing electrical continuity between the test pads (107, 108) reveals the presence or the absence of the score-lines (105, 215).
