Evolution And Innovation In Printed Circuit Board Manufacturing

There is little doubt that you are only able to read this blog with the help of a machine or a gadget that contains a printed circuit board. There is also little doubt that most of us do not have a clue about what a printed circuit board or a PCB is.

In very simple words, a printed circuit board or a PCB is a very thin board that is often made up of fiber glass or another substance with similar qualities. Mostly it is green in color.

Printed Circuit Board: The Basic You Need To Know

A Printed Circuit Board is used in most of the gadgets and electronics that we can find around us, ranging from a simple single sided printed circuit board to the extremely complex multi sided printed circuit boards. Our smart phones, radios, cars, computers and even kitchen appliances have printed circuit boards in them.

Putting it simply the PCB is what makes our smart phones become smarter i.e. slimmer and slimmer, version after released version. It takes up less space and allows the mounting of other electronic components directly on to it. Continue reading

History of Printed Circuit Boards

One of the most revolutionary technological inventions of all time is the Printed Circuit board technology. As fascinating as a PCB is, most people have no idea about the history behind this chip that changed the electronic world completely. Looking at the revolution PCBs have brought into the world, one cannot help but marvel at the great mind that was responsible for sharing this ingenuity with the world.

Paul Eisler, was the genius who invented the PCB in 1936. He was born in Vienna in the year 1907. Seeing his inventions and its contribution to the electronic industry, one undoubtedly assumes he must have seen a lot of fame and fortune. That unfortunately was not the case as Paul Eisler lived a very hard life. Continue reading

Surface Finish Options For Printed Circuit Board

Why is a surface finish one of the most important decisions you will have to make when purchasing a PCB? All PCB basically have copper tracks on them. If left unprotected these copper tracks will deoxidize and deteriorate. The end result is a PCB that is of very little use to you. So, a surface finish basically protects the copper tracks on the PCB from being oxidized.

The most common types of surface finishes for a PCB are; Hot-air solder leveling (HASL), Electroless Nickel Immersion Gold (ENIG), Immersion Silver and Immersion Tin. Lets see the benefits of using each of these types of finishes. Continue reading
