A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. PCBs can be single sided (one copper layer), double sided (two copper layers) or multi-layer (outer and inner layers). Multi-layer PCBs allow for much higher component density. Conductors on different layers are connected with plated-through holes called vias. Advanced PCBs may contain components - capacitors, resistors or active devices - embedded in the substrate.
Inventor of Printed Circuit Board
Paul Eliser is widely credited as the inventor of the circuit board in printed form and this was the invention which made him a great name of the field of electronics sciences. He was in Hampstead those days, when he started his formal work for this invention. Later on, he was hired to work on this thing and as a result succeeded in inventing the first printed circuit board.
Printed Circuit Board
This is also known as a PCB and it works on both the principles of mechanical as well as electrical engineering. The method of its working is that it supports in the mechanical format working on mechanical rules while the mode of connection is taken out through electrical method. In this thing, conductive tracks are used in the way to connect different electronic components electrically and to make it usable.
