Understanding Perfboard and Its Types

A perfboard is a thin, flat sheet of insulating material. It is usually made from fiberglass or phenolic resin. This epoxy fiberglass is a non-conducting material. The pre-drilled holes are arranged in a square grid pattern with a 0.1-inch spacing. These holes are ringed by copper pads. Electronic components can be placed and soldered into these holes, resulting in a working circuit.

The most common applications are the following:

  • Primarily leveraged for prototyping and testing new circuit designs before creating a more permanent solution with a PCB.
  • Frequently used to build custom electronic devices, such as amplifiers, audio effects pedals, and more.
  • Often used in electronics education to teach students about circuit construction and soldering.
