Breadboards are hand-built circuit boards used for prototyping without soldering, allowing for easy component repositioning and cost-effective research. Once complete, it serves as a blueprint for a soldered printed circuit board. Basic models have two areas called streaks with terminals and a notch for safety. Jump wires can be manually made or mass-produced.
Breadboards are hand-built types of printed circuit boards. Sometimes referred to as a prototyping board, the breadboard is often used to create prototypes for new circuit board configurations intended for general purpose or proprietary use in a specific brand of electronic product. It is not uncommon for these prototypes to be assembled without the use of solder, a factor that has led to boards of this type being referred to as solderless plugboards or breadboards.
There are several benefits associated with the breadboard, especially during the process of prototyping a new product. First, because the board components are not soldered, it is easy to reposition or remove some components from the design if desired. The components used in the prototype can also be used later in the research process for other circuit board designs, a benefit that helps keep the cost of research materials to a minimum.
Once a breadboard design is considered complete, the prototype serves as a blueprint for creating what’s known as a veroboard, or printed circuit board. This type of board is soldered, which means that components cannot be reused easily and changes to the board design are difficult, if not impossible. By first creating a breadboard and using that device for testing, you can refine the design before creating the actual prototype used in manufacturing the circuit boards. This process actually helps reduce the cost of making the boards that are ultimately used in everything from central processing units on mainframe computers to circuit boards used in laptops and similar devices.
While a breadboard is a versatile tool, a basic model has emerged. Tables of this type normally use a layout composed of two specific areas on the facing. These areas are known as streaks. Those strips will include a set of terminals that can interact with relative ease. With most basic models, there is also a notch in the center area of each stripe. This notch is intended to help keep the card cool as current flows through the components, a simple but effective safety measure.
In order to ease the building process, there are sets of jump wires made for use with breadboard design. It is also possible to build these jump cables manually, but this process tends to be a bit cumbersome in terms of the time required for the task. Many researchers prefer to use mass-produced jump cord sets, allowing them to spend more time testing the function of a particular breadboard design and making the necessary modifications to achieve the ideal level of functionality.
