A boardview is a specialized file (often in .brd , .bdv , or .cad formats) that provides a 2D or 3D representation of a motherboard's PCB. Unlike a standard , which shows theoretical electrical connections, a boardview shows the exact physical location of every resistor, capacitor, and IC. HP ProBook 4540s

Boardview work cannot be performed without specific software designed to unpack and read CAD-based motherboard files. Software Tool Supported File Extensions Primary Use Case .brd , .bdv , .fv
