Circuit assembly is one of the most important steps in electronics. It is in this phase that the electronic components are correctly connected, according to the electrical circuit diagram. Circuit assembly can be done in several ways, from using protoboards to making printed circuit boards.
Before starting to assemble a circuit, it is important to have all the necessary components and the electrical schematic of the circuit at hand. The electrical schematic is a diagram that represents the connection of components, indicating the values of resistors, capacitors, transistors, among others.
One of the most common ways of assembling circuits is the use of protoboards. Protoboards are boards with holes where components are inserted and connected through conductive tracks. This is a practical and quick way to assemble circuits, as it is not necessary to solder the components.
However, when it comes to more complex circuits or those that need greater precision, making printed circuit boards is the best option. Printed circuit boards are made from a circuit design in specific software, which is transferred to a copper plate through a chemical etching process. After that, the components are soldered on the board, following the electrical circuit diagram.
Regardless of the chosen assembly method, it is important to take some precautions to ensure the proper functioning of the circuit. It is necessary to pay attention to the polarity of the components, respect the values of the resistors and capacitors indicated in the electrical diagram, in addition to avoiding short circuits and poorly made solders.
Finally, it is important to remember that assembling circuits is an activity that requires patience, attention and technical knowledge. Therefore, it is fundamental to study the basic concepts of electronics before starting to assemble more complex circuits.
