The breadboard is a universal printed circuit board, that is, a surface specially designed for mounting a variety of radio components. It has hundreds of holes, which are electrically connected with metal strips. The conclusions of microcircuits and radio components are inserted into these small holes, and then connected by means of pieces of stripped wires. At the same time, the rows of contacts located at the top, bottom and in the middle of the board are designed to connect the numerous points of the circuit with ground and a power source. It should be especially noted that the breadboard does not require a soldering iron, flux and solder. In addition, when working with it, there is no risk of overheating of the part, and also there are no difficulties with repeated installation of circuits.
Types of breadboards
Currently, experts distinguish three main types of prototyping boards. Firstly, these are universal models, on the surface of which there are only
plated holes. Subsequently, the developer will have to connect them usingjumpers. The second type is specialized boards. On such surfaces there are both standard chains (pre-wired) and tracks and holes designed for non-standard chains. And finally, the third type is a printed breadboard designed for digital devices. In this case, power rails are drawn across the entire surface, as well as the intended places for microcircuits.
DIY Breadboard
Making a homemade board if necessary is quite simple and anyone can do it. As a material for its base, non-foil textolite is best suited. In this case, the lines of the breadboard can be applied using a ruler and a sharp awl. As for the holes, they can be made using a drill 0, 8. The conductors themselves can be made of copper wire, and the necessary radio components are installed by soldering. In this case, all elements are not attached from the bottom side, but from the top. In addition, it is very important that the conclusions
radio components were bent so that they run parallel to the contact conductors. Breadboard base ready!
Breadboard Application Problems
Developers who, by virtue of their activities, constantly use prototypes of various electronic devices, note that their use is usually associated with a number of problems. The first of these is the most obvious and lies in the fact that any prototyping board is soldered by hand. And if an error is made in the circuit, it has to be re-soldered. Secondly, it should be said that in order to create a single prototype of an electronic device, it is quite often simply unprofitable to make a printed circuit board. Thirdly, if circuits on analog microcircuits of a low degree of integration are allowed to be carried out by a hinged mounting method, then microprocessor equipment is very difficult to do so. Considering all these aspects, it is necessary to analyze everything in advance before starting to work with a device such as a breadboard.
