IPC 2D Panel Barcode (IPC 2D)
QR Code or Data Matrix applied to bare PCB panels and assembled boards to encode manufacturer ID, panel lot, revision level, and assembly routing data throughout SMT and wave soldering lines.
Governing Specification: IPC-2D-001 / IPC-2581
Data Format & Required Fields
QR Code or Data Matrix encoding structured board identity: manufacturer CAGE code, work order number, revision, panel ID, and optional IPC-2581 digital product model reference.
Allowed Character SetAlphanumeric board ID, work order, revision, and panel sequence.
Payload Length Rule Between 6 and 100 characters
Example Valid Format
PCB-PRX-WO2026-REV-C-PN-001-PANEL-04Industry Guidance & Practical Applications
- SMT pick-and-place machine feeder verification and board identity checks
- Wave solder, reflow oven, and AOI traceability across PCB assembly stations
- Board repair depot and RMA return tracking in contract electronics manufacturing
Packaging & Scanning Notes: Essential for IPC Class 3 medical and aerospace board assemblies requiring full component-level traceability.
Symbol Constraints & Label Guidelines
- Labels must survive solder reflow temperatures (up to 260°C peak); requires polyimide substrates.
