Did you know that Printed circuit boards (PCBs) are not limited to straight lines? PCBs are usually a flat laminated composite made from non-conductive materials with layers of copper circuitry covered internally or on the external surfaces. They can be as simple as one or two layers of copper or in high density applications they can have 24 layers or more. For efficiency PCBs are manufactured in a panel with a number of circuits and use break-off tabs to de-panel. “Mouse bites” are a line of tiny holes in a PCB board just like the holes around postage stamps, permitting small PCBs to be used in an array. Drilling these holes leaves rough edges of extra remaining material sticking out the side. While a V-groove PCB with a V-scored top and bottom provides neat smooth de-panelling. Non-rectangular outlines are routed and usually supported with mouse bites or small tabs.

“Through hole” components are mounted by their wire leads passing through the board and soldered to tracks on the other side. “Surface mount” components are attached by their leads to copper tracks on the same side of the board. A board may use both methods for mounting components.
