PCB Full Form - Printed Circuit Board

 Printed Circuit Board

Printed Circuit Board

  • PCB stands for Printed Circuit Board.
  • It's an electrical circuit within the kind of a thin board made from a non-conductive material that completely holds copper circuitry like fiberglass, plastic, composite epoxy, etc.
  • Its conductive paths printed on that to attach different components, like resistors, transistors, integrated circuits, etc. It provides mechanical support and a pathway to its electronic components for the flow of current.
  • PCBs are used in all electronic and computing devices like TVs, digital cameras, tablets, cell phones, etc., including motherboards, network cards, graphics cards, and internal circuitry boards of hard drives.

Types of printed circuit Boards

 Types of  Pcb

Types of Pcb

Single-Sided PCBs

 Single Sided Pcb

Single Sided Pcb

  • It is made from one layer of substrate or base material.
  • It’s one side is coated with a layer of metal, which is typically copper because it is a superb conductor of electricity.
  • The metal coating is coated with a protective solder, which is additionally covered by silk-screen to mark out all of the weather on the board.
  • These PCBs are easy to style and manufacture as their circuits and components are soldered onto one side.

Double-Sided PCBs

 Double Sided Pcb

Double Sided Pcb

  • In this type of PCB, each side of the board is coated with copper.
  • Holes are drilled within the board to attach the circuits on one side to the circuits on the other side.
  • This type of board connects the circuits on all sides using either through-hole technology or surface mount technology.
  • In through-hole technology, the small wires, which are referred to as leads, are skilled the holes, and every lead is soldered to an appropriate component or circuit. Whereas, in Surface mount technology, rather than wires, small leads are soldered directly onto the PCB.

Multilayer PCBs

 Multilayer Pcb

Multilayer Pcb

  • They are made from several layers of substrate boards which are separated by insulating materials.
  • They are available in several sizes as small as four layers or as large as ten or twelve layers.
  • Multi-layer PCBs are suitable for using in File servers, Data Storage, Satellite systems, GPS technology, Weather analysis, and Medical equipment.
  • A bit like double-sided boards, the components on multilayer boards are connected through holes or vias on the board.

Rigid PCBs

 Rigid Pcb

Rigid Pcb

  • They are made from a solid, rigid, substrate material like fiberglass that keeps the board from twisting. For example, a motherboard within the tower of a computer is an example of inflexible PCB.

Flex PCBs

 Flexi Pcb

Flexi Pcb

  • They are made from a flexible substrate, typically a flexible plastic. The flexible material permits the board to suit into forms without affecting the circuits on the computer circuit board.
  • These boards can restore heavy or bulky wiring in superior gear like satellites, where weight and space matter.
  • Flex boards also can are available three formats: single-sided, double-sided or multilayer formats.

Rigid-Flex PCBs

 Rigid Flex

Rigid Flex

  • They are both rigid and versatile. So, they provide more benefits than the rigid or flexible PCBs surely applications. For example, they create possible streamlined design, and reducing the general board size and package weight. These are used with devices that need a strong board.
