DPM(Direct Part Marking) Barcode

What is a DPM Barcode?

DPM

– Direct Part Marking

– DPM is the process of marking a permanent 2D barcode onto the part’s

surface in order to provide full traceability throughout the lifecycle.

– DPM makes it practical to identify almost anything, including small,

hard-to-label items.

– With DPM, expensive and/or mission critical parts and components can

be encoded with their serial number, lot code, configuration information

or other essential data.

The Advantage of DPM

Error proofing

Part traceability

Part authenticity

Supply chain management

Increased productivity

Many industries are now implementing parts tracking using DPM ID !!

4 Marking Methods

Laser Marking Ink Jet Marking

Dot Peen Marking Electro-Chemical Etch Marking

DPM Applications

Semiconductor -Wafer

Aircraft – Turbine blade Pharmaceutical - Vials

Automotive –

Engine components

Electronics - PCB Cell phone –

Camera Module

DPM Applications

Package Assembly – Micro PCB Medical – Surgical instruments

DoD – Machine, ID Optics – Lens tray

DPM Objects

Laser Mark on Exhaust Dot Peen Mark on Plastic

Dot Peen Mark on Casting

Laser Mark on Rubber

Laser Bonding on Glass Laser Mark on Wheel

One can mark almost anything !!

Challenges

Challenging points in DPM

– DPM often have very little contrast, because they are stamped or etched directly onto the metal and may be covered by grease, dirt or wear marks.

– A light source from the reader can create shadows, or may make the symbol too bright to read if the surface is reflective.

– Dot-peen type DPM(round-type) is different from normal paper barcode(square-type). It requires special image signal processing.

– DPMs on curved surface.

Good DPM barcode reader

– The reader has to be adaptive for a range of conditions.

Operating Modes

Continuous Mode

– Repetitively acquires barcode images as fast as possible regardless of

trigger source.

– If one defines code depth FIFO, one can avoid reading the same code.

OneShot mode

– Acquire single image

after receiving trigger.

Burst mode

– Acquire several images firstly and

decode after all images are ready.

– Good for recognizing barcodes on

moving object.

External trigger
