Hey Guys! Hope you are doing great. We always enjoy when you come back to our site for useful information so you can excel and grow in your relevant field. Today, I am going to reveal the details on the Introduction to PCB. It is a printed circuit board that uses pads, tracks and lines incorporated on a single board to electrically connect the electronics components. I'll discuss main features of PCB and what makes it very useful in latest technology? Let's hop on the board and dive in the details of PCB.
Introduction to PCB
PCB is a acronym of Printed Circuit Board that helps in connecting the electronics components with pads, tracks and lines incorporated on a laminated copper sheet.
It is considered as an insulating material which can be developed using epoxy on which copper layer is laminated.
PCB design has been evolved in an amazing way and revitalized the latest technology. You can have a look at top 10 PCB design software.
Before the inception of PCB, professional used laborious method of point to point wiring to connect the electronics components. This method was costly and lead to a most complicated design.
In order to get rid of end to end wiring and make the circuit design hassle free, first PCB was developed by Australian Engineer Paul Eisler.
With the passage of time demands of electronics became prevalent, this made professionals think they should come up with an ideal solution that made the electronics cheap and incorporated in a lesser space.
This was the start of PCB that revolutionized the electronics industry with lots of innovation and productive ideas.
Mostly, PCBs are composed of composite material, composite epoxy and fiber glass.
These are the most common components used in electronics devices that makes the circuit design sophisticated and compact.
PCBs come in different layers and multiple designs. PCBs used in simple electronics are composed of single layer. Most compact and advanced hardware like graphics card and motherboard are composed of multi layers PCBs.
PCBs are not associated with computers only, they are widely used in advanced electronics including digital cameras, cell phones, TV, scanners and automatic control systems.
In these boards, copper tracks are applied on both sides of the boards.
In order to provide link between two points on the both side of the boards, holes are created on the boards and then laminated with the copper layer.
The components on these boards are electrically connected using two techniques i.e through hole or surface mount technology.
Using through hole technology, leads also known as wires are inserted in the hole and then each lead is connected to the right component and build a smooth conducting path throughout the board surface.
Wires don't behave as connectors in surface mount technology, instead whole board provides a wiring surface where small leads are directly connected to the board.
Different functions can be accomplished at a much faster rate with less space using surface mount technology which helps in minimizing the cost and makes the whole project light weight.
Double sided PCB boards are widely used in many applications including amplifiers, vending machines, LED lightening, HVAC systems and general power supplies.
These boards are then glued together with pieces of insulation in order to avoid excessive heat that can damage the components.
Multi layer PCBs come in different forms ranging from four layers to 16 layers or more.
The thickest multi layer PCB ever developed by professionals was 50 layers thick.
These boards are more complex than double layered PCBs, help in initializing faster operations than standard PCB boards and are very similar to microchip composition.
Multi layer boards are used in wide range of applications including satellite system, weather equipment, x ray equipment, data storage, GPS technology and many more.
I have discussed types of PCBs based on number of layers, however, there are other types too like Aluminum PCB and High Frequency PCB, but they are used for more robust applications where heat dissipation is required.
1: PCBs are widely used in industrial machinery for many useful applications. Thick copper PCBs are a great replacement of thin copper PCBs in many situations. Thick copper PCBs are suitable for many applications including motor controllers, industrial load testers and high current battery chargers. There are many software to make PCB design, however, if you are involved in embedded system you may like designing PCB in Proteus Ares.
2: Latest technology used in most of the electronics uses less power than their prior editions, making it economical and widely used in medical field. Most of the advanced medical equipments use high density PCBs that provide compact and smallest design possible. Small size and light weight of PCB beautifully replaces the old traditional equipments and becomes an ideal choice for medical field. These devices are useful for a range of applications from small component like pacemaker to large complex machine like X-Ray machines and CAT scanner.
3: Aluminum backed PCBs are widely used in LED based lighting systems which encompass low power consumption and high level of efficiency. These PCBs are capable of transferring heat from one point to another and are considered as a step ahead from standard PCBs. These PCBs are the back bone of basic lighting solutions and LED applications.
4: Automotive and aerospace industries are widely surrounded by vibration environment, this is where flexible PCBs come into play. These PCBs can withstand high vibrations and severe environments due to their flexible and compact design. They can house in tight spaces like instrument gauge and instrument panel. Being a light weight makes it an ideal choice for making manufacturing parts of transportation industries.
