Main Parts of PCB Board

Hello readers welcome to the new tutorial. Here we will discuss the Main Parts of the PCB Board. PCB board is the main part of any electronic component and project. This board is now a very significant part of any module and applies in every circuit. It has a configuration of different component symbols on the board where configurations are arranged to make the projects.

It is created with the combination of different parts that we will discuss. PCB comes in different types such as single layers multilayer, and double layers. Each type of board has its features and applications. Here we will cover details about its different parts. With this, we will discuss how you can get a good PCB board at good rates from PCBWAY.

What is the PCB Board

• The PCB board is a circuit board used for component assembly and connections are configured that help to pass current between components.
• The baseboard is made with rigid nonconductive materials, but flexible base materials are also used.
• Electronic components like diodes, inductors, resistors, and transistors are configured on board and traces help to make connections between components.
• PCB boards help to make circuits of different devices and projects on board. Such as different devices come with PCB boards such as laptops, tablets, smartphones and smartwatches, and some other IoT devices.
• PCB also helps to provide communication systems and also part of industries and medical devices,aviation.

How to get PCB Board

• Various PCB-based companies are operating in the world that provide various PCB-related services and other features.
• As a result, they also offer different features and services to their users to receive different prizes and coupons to get services at affordable prices.
• There is one of the best and most efficient PCB service providers that offers PCB-based features and various services to its users. That well-known and prominent PCB service provider is PCBWAY. PCBWAY is a China-based PCB manufacturer that provides a variety of PCB-related services to its users at affordable prices.
• PCBWay is the manufacturer of a combination of PCB and PCB composite. Shenzhen has for decades been a global center for electronics R&D and manufacturing. By surpassing all middle-class companies, they succeed in delivering savings and bring complete satisfaction of PCB / PCBA purchasing experience to their valued customers. That’s why 100% of our old customers come to us to get their future orders.

PCB Pad

• The position where components of projects are connected on the board and that area is created with copper.
• These pads help to make the firm connection of components to the board and strong support.
• There are 2 main categories of PCB pads first one is surface mount and the second one is through the hole.
• In surface mount pads like the SMT components are positioned on the board and in through hole pad components the pins are connected on the board by making the holes on the board like the through hole techniques.

SolderMask

• It is a thin liquid layer created with polymer and applied on the PCB traces to protect the board from external environmental conditions such as oxidation.
• It also decreases the creation of solder bridges created in the solder pads.
• Solder bridges are connections created between the two conductive points on the board.
• The application of a solder mask reduces the chances of short circuits.

What is Silkscreen

• The upper layers of the pcb board are called silkscreen where different components are connected.
• At this part of PCB, different symbolic representations of components are made to connect these components to make a circuit.
• It comes in different colors such as red black yellow as well blue and in standard color is white mostly used is green color.

PCB Vias

• Vias of pcb board help to make the connection between pads and traces on the board.
• These vias help to decrease the size of the board when joining the different layers of the board.’
• These vias are created by placing the copper pads at every layer of the board and making holes.
• In the inner area of the hole, electroplating is placed to make conductive parts.
• normally three main vias are used in PCB board. Buried, Blind and through hole”

Design

• The schematic on the board is a configuration where components of circuits are assembled on the board.
• Different configurations exist in these parts such as solder paste, solder mask silkscreen
• The features of schematic changes are based on different parameters needed.

Some main PCB assembly components are

Resistors

• Resistors are the main component and are mostly used in PCB boards. It transmits current for generating voltage and dissipates power in the form of heat. It is made with the use of different materials and has color combinations for finding value resistance.

Transistors

• The transistor is used as an amplifier and switch and works as a control signal. Transistor comes in different types such as bipolar transistor that has 3 pins base emitter and collector.

Capacitors

• It is a common component like a resistor used in PCB assembly. Capacitors store charge in board and release when power is needed on the circuit, normally gathering charges on two conductive layers, parted with insulating materials

 Inductors

• It is like a capacitor and stores energy in the form of a magentic field when the current passes. It is used for signal blocking in board like the interface of other devices

Transformers

• It is a device that is used for changing the voltage level from high to low or low to high..

 Diodes

• The diode is a component used for conversion AC into DC for one part of the wave and not for the other part.So it is used for blocking current in one direction and allow to flow in another. Common types of diodes are LED

PCB Applications

• Pcb has used various communication tools such as cell phones, clocks, radios, etc.
• All types of computers such as PCB motherboards, such as personal computers, tablets, laptops, or other workstations.
• It has been used on all Media Player devices such as TV, DVD, and various types of games we play.
• Everything used in our homes is made on PCB like microwave ovens, refrigerators, clocks, etc.
• Different industrial equipment also PCBs to integrate different electronic components.
• All types of equipment use a PCB to perform their design such as ups, inverters, or other power devices.
