The basic electronic components are divided in two main groups: active and passive. The Passive elements are those that do not require any power to operate or are unable to control the current, whereas the active elements require some power to operate and can easily control the flow of current in a PCB circuit board. The passive electronic components are resistors, diodes, capacitors etc. and the active electronic components are transistors, Integrated Circuits (ICs) etc.
PCB of Electronic Components
Connectors: The connectors serve the purpose of making the electrical connection among the components.
Resistors: They are used to resist the certain flow of current. One must think why we are choking our own throat by placing the resistors. For example a certain diode needs very small of amount of current to work, if we do not use the resistor then a big value of the current will directly supply to the diode making it dead.
Switches: Switches are used to flow or no-flow the current.
Capacitors: Capacitors are used to store the electric charge in a PCB circuit board and other circuit boards. When needed, they provide their stored charge to the required components.
Diodes: Diodes are the semiconductor devices which are used to allow the current to flow in one direction only.
Transistors: It is also the semiconductor device used in the PCB circuit board and other circuit boards to amplify the current.
ICs: They are the whole system or computer made from different components in a single chip.
PCBs are an important part of every electrical device and therefore they have to be quality and well-produced. For this reason, many manufacturers are looking at the materials and technology they use in the manufacture of PCBs. A good PCB assembly manufacturer is needed in many fields, and the demand for them is really huge in every country.
