In repair archives a .pcb is typically an XZZ (XinZhiZao) boardview — popular for phones and recent laptops.

What is a .pcb file?

XZZ .pcb files are encrypted and include resistance and diode-mode reference values next to the layout. They open in the XZZ viewer and in recent OpenBoardView and FlexBV builds.

The extension is also used by unrelated CAD tools (Altium, PADS). Those are design databases, not repair boardviews, and need the original CAD software.
