PCB

Definitions

1. Printed Circuit Board — a laminated board of insulating material with conductive copper traces etched onto its surface, used to mechanically support and electrically connect electronic components.

   In plain English: The flat green (or other color) board inside every electronic device that holds all the chips and components in place and connects them with thin metal pathways, like a city's road network for electricity.

   Example: "The four-layer PCB came back from the fab house with a short between power and ground. DRC passed, but the manufacturer's minimum trace spacing was tighter than specced."
