The components of a printed circuit board may come in different types,with each of these functioning by regulating and controlling the flow of a specific circuit.The standard PCB, though, includes 5 components for it to function properly.
These components are what you’d normally see inside common electronic devices such as handheld radios and mobile phones. Each of these components has their designated place inside the surface of the PCB so that they could make the electronic circuit work.
The capacitors are the parts that look like small cylinders sticking out from the surface of a printed circuit board. The primary function of the capacitor is to serve as storage for the electrical current. By facilitating the flow of the current, the capacitor becomes a means for other PCB components to receive a constant power supply. If the capacitor is not placed in its designated position, the device will not work properly. This bad positioning of the capacitor may also lead to the eventual failure of the entire electrical device.
The resistor is the component that resembles a tube with colored stripes found on its exterior-
The primary function of this component is preventing the entry of too much electrical current to the circuit area. The total current that a particular resistor can hold is greatly dependent on the resistance rating of the component. The stripes on its surface determines the resistance value referenced by the PCB assembler during the design of the board. If a resistor is not placed in the correct position, the other components on the PCB could become damaged given the excessive amount of current flow they’ll receive.
The diode is the part responsible for directing the flow of current to the other components on the printed circuit board. As soon as electrical current goes into and out of the diode, the direction of electrical flow cannot be reversed through that exact same diode. In order to reverse the flow of the current, a barrier is formed by the internal design of the component. With this kind of flow blockage, the microchips would be protected from the possibility of too much current flowing through the component.
The transistor is the part of the printed circuit board that can function by amplifying the amount of current flowing through other components or redirect electrical current to another component. On a standard PCB assembly, the transistor has 3 legs stuck onto the board, which makes them distinctive given that other components usually have a pair of legs attaching to the PCB. The amount of electricity can significantly be increased by the transistor and then directed to a specific region of the circuit. This PCB component can also redirect the flow of the current so that another area in the circuit could receive power. This is what happens when you are pressing different buttons on the remote control of your television.
The integrated circuit is what you can consider a minute printed circuit board inside the actual PCB.
This is contained inside a square or rectangular-shaped chip that you can easily hold at the tip of your finger is what determines how big or small the electronic device can be. This component is primarily responsible for the way cell phones are becoming smaller and smaller with time. Because of how IC’s are being featured in smaller sizes, more circuitry can now be placed inside a chip. This boost in capacity for every unit area allowed newer cell phones to have a lot more features than older but similarly-sized models.
Each of the components inside a PCB assembly is very important in keeping an electronic device functional. A single component being placed in the wrong area could easily render the device inoperative.
