ALL ABOUT PCB

Printed Circuit Boards are commonly known as PCB. There are electrical and electronic components are connected on the board. In the designing phase any pcb is connected via wires for testing purpose. It is very complex and very hard to test. The wire connections are not suitable for large applications like motherboard. Components are internally connected without wires in the PCB which decreases the overall complexity. PCBs can design as per the requirements. It is found in most of electronic devices like TV, Cell Phones, Computers, Camera etc. It is also used in communication devices, defence equipment etc. India Circuit is leading pcb manufacturing companies in india.

There are two types of Mounting processes are used Through-hole and Surface mounted.

First is through-hole PCB. There are holes made on the circuit to mount the leads of the components and it soldered on the other side of PCB. In the through-hole process the components have support from PCB for performance and this is widely used for mount the components on PCB. As there are holes are drilled in the PCB the manufacturing cost is increased. This is suitable for single-sided PCB but for double or multilayer it is not recommended.

The next method is surface mount. In this process there is small size components with small or no leads are used. In this process the components are directly mounted on the board and the holes are not required to mount. After mounting process, the solder paste is applied to hold components on the surface of PCB.

PCB construction is depending on the requirements. It is in single layer, double layer or multilayer.

Single Sided PCB

Double Sided PCB

Multilayer PCB

Rigid PCB

Flexible PCB

Rigid-flex PCB

Single Sided PCB 

First in the list is single-sided PCB. It is also called single layer PCB. It is widely used as it has simple design and easily manufactured. There is copper applied on the one side of PCB as the copper has better electric conductivity than other materials. The solder mask is applied to prevent the damage in the process of silkscreen coat for marking of components on the PCB. There is an electric component on the single side. The components are soldered on the other side of the PCB. Single sided PCBs are cost effective and it is best option for bulk manufacturing. Single sided PCBs are used in devices like printers, calculators etc.

Double Sided PCB

It is also known as double layer PCB. There is copper coat on the single side and in the double side the copper coating is on the both sides. The two layers are connected with hole made on the surface. The price of double side is low and are suitable to make complex circuit with compact size. Double sided PCBs are used in gaming motherboard, gaming pc, mobile phones, Inverter, Amplifies etc.

Multi-Layer PCB

There are more than two conductive layers in the multilayer PCB. There is glue is applied between layers to protect components from heat produced while performance. It is used for a complex circuit with compact size for best performance. This type of PCBs is used in satellite system, data servers etc.

Rigid PCB 

Rigid PCB is made from solid material which is very strong. It can be made in single layer, double layer and multilayer. The shape of PCB remains same after installation. It is not bent as per base. Rigid PCBs are long lasting. This PCBs is used in CPU, RAM and GPU. Single sided rigid PCBs are most used as it has simple design.

Flexible PCB

The material in the PCB makes it flexible. There is conductive plastic is used. Flexible PCBs are used where the rigid PCBs is not. It has very complex design and it is made in single sided, double sided and multilayer. This is used in LED, Solar Panel, Laptops etc.

Rigid-Flex PCB

This is a mixture of the Rigid and Flexible technique. Rigid-Flex contains number of rigid circuits are connect with flexible circuits. It is used in camera, cell phones etc.

We hope that this information is helpful to choose PCB according to your need.
