Posted:11:40 AM April 26, 2023 writer: ​NextPCB

Types of Prototype Boards

There are different types of prototype boards that have their own strengths and weaknesses. Below are some examples of common prototype boards.:

  • Breadboards: Breadboards are the perfect platform to explore and experiment with circuit building - they provide a reliable canvas for electrical engineers, makers, hobbyists, educators, and students alike. They have a grid of holes that allow components to be inserted and connected without soldering. There are different sizes and colors of breadboards available.

  • Perfboards: Perfboards have a grid of holes like breadboards, but they do not have the pre-arranged connectivity of breadboards. Components are soldered onto the board, and wires are used to connect them. Perfboards are more permanent than breadboards, but they are also more flexible than stripboards.
  • PCB prototype boards: PCB (Printed Circuit Board) prototype boards are designed to look and function like production PCBs. But with the added flexibility of being able to modify and experiment with the circuit. They are made of a copper-clad board with a pre-designed circuit layout. Components are soldered onto the board, and traces are cut or modified to change the circuit. 
  • Wire-wrap boards: Wire-wrap boards use wire-wrapping technology to connect components instead of soldering. Wire-wrap boards have a grid of holes, and each hole is connected to a pin with a wire-wrap post. Wire-wrap boards are more durable and reliable than other prototype boards. But are also more expensive and require specialized tools and skills to use.
