What does a Printed Circuit Board do?
A PCB (Printed Circuit Board) and its components are used in most electronic devices. They are used to mechanically support and electrically connect the electronic components using conductive pathways created using, track or signal traces which are etched from copper sheets laminated onto a non-conductive substrate.
PCBs are everywhere. Computers, printers, televisions, digital clocks, pacemakers, 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 connected to a power source while being safely insulated.
Printed Circuit boards are less expensive than other options because they can be designed and manufactured with digital tools and manufactured in high volumes.
