What is a printed board circuit?
A printed circuit board is a non-conductive material on which the conductive lines are etched or printed. The presence of the electronic components & the traces connects the board components. Through these connections, a working circuit or assembly is formed.
The printed circuit board is also known as PCB or PC board. It’s a rigid structure that assembles different types of electronic components to support the working of many electronic devices. It’s mostly used as mechanical support and an electrical connection using conductive pathways from the laminated copper sheets onto a non-conductive substrate.For more detailed information and manufacturing services, visit the One-stop PCB&PCBA Manufacturer.
How Is a PCB Manufactured?
Mainly the PCB manufacturing starts with the pre-designed & verification. Afterwards the fabrication of the circuit board is introduced. Later on it requires machine-driven tools, guidance from computers. This is done to prevent damages from the incomplete circuits or it also prevents from the short-circuit.
Many companies are manufacturing PCBs on a commercial level. Some of the top manufacturers of PCB are as follows;
- Genus Electrotech Ltd
- Shogini Technoarts Pvt. Ltd
- Ascent Circuits Pvt. Ltd
- Epitome Components Ltd
- Anand Electronics
Components of Printed circuit board
The PCB is made from the electrical components & PCB materials that include the following:
- Resistors
- Capacitors
- Transistors
- Inductors
- Diodes
- Transformers
- Sensors
Layers of printed circuit board
Depending on the type of PCB the number of layers in it varies. Whatever the type it has, it’s made up of following four types of layers that are as follows;
1. Copper Layer
This layer is made up of thin copper foil. With the help of heat, this layer is laminated on the board. The PCB with a higher level of copper has a higher level of power in it.
2. Substrate Layer
The rigidity in the PCB is due to the presence of this substrate layer. It’s made from fiberglass or epoxies. However, fiberglass holds durability more than the epoxies layer.
3. Silkscreen Layer
This layer is used for the ease of humans. This layer adds up the numbers, letters, and symbols. It makes it easier to understand the LEDs and pins according to their functionalities.
4. Solder Mask Layer
This layer is carefully deposited so that it doesn’t connect any elements. Mostly it gives the green appearance on the board. This layer insulates the Copper layer.

All of the electronics devices we are using include the PCBs in their formation. Most of the devices focused on advanced functionalities including these all. It’s present within all the communication, home appliances & computer devices.
- Uses In Industrial Sector
The industrial sector requires highly powdered and durable PCBs in their equipment. They are used in upgrading devices to deal with high temperatures, durable metals, vibrating machinery, and rough handling.
Majorly these are useful in the measuring and power equipment. Robotics or tech-related machinery are using PCBs.
- Automotive Industry
In automotive components such as sensors, control & navigation systems are using the integrating systems of the PCBs. These are useful in the sensors that help in the detection of nearby objects and identify spots.
- Defense Application’s
PCBs are useful for the preparations of military or defense equipment. Due to the presence of PCBs, the devices can be exposed to extreme conditions. It’s useful for the preparation of the missile detection systems and jamming systems.
- Telecommunications
Cell towers transmit the signals from the cellphones using the PCBs. Routers, phone switching systems, modems, and (VoIP) devices are also using the system if PCBs are in it. The LED indicators & displays also utilize the PCBs.
- LEDs
Through the LEDs, these are highly useful for the computer, technology, medicine & automobile industries.
- Aerospace
In the Aerospace component, the PCB is used to handle Extremely harsh conditions.
- Other Uses:
Aside from the above-mentioned uses, it’s also useful in almost all Appliances, Maritime applications, Media devices, Internal devices, Lighting, and other purposes.
