Perfboard is a base for prototyping circuit boards. It has holes pre-drilled at set intervals across a grid. Perfboard can be used for wire wrap prototypes and for solder prototypes. Copper or another metal can be plated onto the substrate in pre-arranged patterns. Discrete components are attached to the prototype board such as resistors, capacitors, and integrated circuits. The substrate is typically made of fiberglass or synthetic resin bonded paper.

To use Perfboard you would solder on the bottom of the board and scrape away the copper where you do not want connections. (see photos below)
