A perfboard is a rectangular sheet covered in a grid of through holes that can be used for soldering. Holes are connected by either running a wire between them or be making a solder bridge. Many also include pads on the side for surface mount components. Perfboards are more durable than breadboards and can save time when only one or two designs are needed. However, they are not recommended for circuits that are complicated or need to be replicated many times. |

+ | The rest of this article focuses on PCBs. If you are not sure which technique for implementing your circuit design is best for your project, you can talk to a PI about the advantages and disadvantages of different methods. Keep in mind that for most projects, you will use multiple implementation methods as you develop your design. | ||

+ | A PCB is a multi-layered substrate specially designed and fabricated for circuit designers to eliminate wiring and mechanically support their components. At their simplest, they are single layers of copper on a rigid, electrically isolated backing, onto which you can solder components and cut connections between them out of the copper.
