What does a Printed Circuit board (PCB) do?

A PCB (Printed Circuit Board) and its components are used in the majority of electronic devices so they can perform their intended function. They are used to mechanically support and electrically connect electronic components using conductive pathways, track or signal traces etched from copper sheets laminated onto a non-conductive substrate.

PCBs are everywhere! Computers, printers, televisions, digital clocks, microwaves and you’ll even find one in your mobile phone!

Aside from the tasks it performs, the most important function of a circuit board is providing a way to integrate the electronics for a device in a compact space. A PCB allows components to be correctly connected to a power source while being safely insulated.

Circuit boards are less expensive than other options because they can be designed with digital tools and manufactured in high volumes.
