What are the different components of the printed circuit board?

The components of the printed circuit boards are available in many different types for control and control of electric flow through a particular circuit. Resistors, capacitors, diodes, transistors and integrated circuits (ICS) are the most common of all ingredients used in almost every electronic device, from mobile phone to hand radio. These components must be placed in strategic positions along the surface of the PCB (PCB) to create a useful electronic circuit.

The resistor is a tube component that usually has specifically colored stripes along its outer surface. Its main purpose is to prevent excessive electric current from entering the circuit area; Each resistor can only stop a certain amount of current based on the assessment of the component resistance. External stripes mean the value of the resistance to which the assemblies refer to when creating a PCB. Incorrect resistors can result in damage to other board components from printed circuits from high current Tmesh.

Capacitors resemble small cylinders that usually stand out from the PCB surface. These components of the printed circuit use the cylinder to store electric current; The capacitor allows some current to flow from the storage space and create a permanent power supply to the rest of the PCB. The electronic device as a whole may not work properly if the capacitors are incorrectly located. As a result of poor or incorrect capacitors, the electrical flow of the device may have large variations that cause components failure.

The

diodes ensure the power of the electric current through the components of the circuit board. As soon as the current enters and leaves the diode component, the electric flow cannot reverse the direction with the same diode. The internal design of the components is a barrier to reverse current; This roadblock is particularly useful for protecting sensitive microchipus that can easily fail of excessive ELekTrick flows.

Transistors are components of the plate circuits that can either amplify the electric current or switch it to another part of the perimeter. They usually have three legs that attach to the PCB instead of a typical two -legged design. Electricity can be multiplied in the transistor and directed to a specific area of ​​the circuit. It can also change the direction of the current flow to power another area of ​​the circuits, for example, when the buttons are pressed on a television remote control.

Integrated circuits are basically small PCBs in a small microchip. These components of the square printed circuit board allowed to reduce electronic devices, as more circuits may be contained in a smaller case. As a result, remote controls and mobile phones gradually decrease over time.
