Perforated circuit board with copper strips, ideal for prototypes and one-off designs.
Components are mounted though the holes, then soldered to the copper strips. The copper strips can be cut easily to make the desired connections between components.
Actually, O ordered BOTH this branded stripboard AND Rapid's own-brand stripboard, and have been so pleased that they are both of top quality. So either way, the stripboard from RAPID is Wunderbar, so to speak. (In the past, I have known stripboard from other "value" suppliers to be a bit irregular in their 0.1 inch pitch, but these are spot-on. Thanks Rapid!!
