In today’s world Printed circuit boards have become very popular that it needs no introduction. In this article we will learn more about these PCB, their types, materials used in making them, and some basic terminologies and concepts associated with their design. These Printed circuit boards are also called as Circuit Boards or PCB for short. This created a drive for a better solution which led to the development of the Printed Circuit Boards in the year 1936 by Pail Eishler. At this point, due to the rise in demand, it no longer made sense to keep using old methods of manufacturing electronics like wire wrapping as they were time consuming and costly. This called for a new method which will be more reliable and compact for building electric connections between components.įurther as the silicon and integrated circuits became more popular in the 20th century, the size and cost of electronic components began to decrease and the demand in electronics products increased. But as the circuits became complex they created a huge mess and occupied a lot of space in final products. In this method the leads of components were actually wrapped (coiled) with other leads to form connections. In earlier times a method called wire wrapping was used by engineers to create permanent connections. While breadboards and dot boards might work for small circuits and design validations it is not practical to use them in final products or in larger circuit. An average electronic circuit could consist of anywhere between tens to hundreds of components in it.
