CPI's New Printed Electronics Line-bringing interactivity to print Neil Porter October 31 st 2012

Centre for Process Innovation (CPI)

• UK-based technology innovation centre • CPI’s Printable Electronics Centre focuses on design, development and prototyping for the emerging printable electronics industry

BPIF Labels Technical Seminar

Aim

•

To demonstrate that any label converter using commercially available equipment can be part of the Integrated Smart Systems supply chain through printing of conductive inks in a standard pressroom

Technology Areas

OTFTs for Flexible Arrays © Visionox © Sony CPI Printable Electronics Process Equipment & Materials Technologies © Aveso ) Solid State Lighting (SSL) Thorn Moisture / Gas Barrier Films Integrated Smart Systems (ISS) and Sensors © Molecular Vision Solar Cells

Integrated Smart Systems (ISS)

• Integrated Smart Systems are functional items produced by the integration of electronic components with circuits prepared by traditional printing processes

Printed Electronic Devices

ISS technology

Market Areas

• Food/drink, tobacco, cosmetics, music, software & FMCG packaging • Pharmaceutical/healthcare applications • Publishing • Advertising • POS/POP • Lightweight, robust inexpensive wiring looms • Automotive, Aviation, architectural & military • Within consumer products & industrial goods • Brand protection & anti-counterfeit

ISS Equipment Criteria

• Print industry recognised equipment and processes • Non clean room location • Versatile enough to support wide range of applications • Cost effective to run for development work but also capable of small scale production runs • Sufficiently instrumented to provide process feedback • Ability to offer an upgrade path to support the ISS technology roadmap

Layout of ISS Line

Print Circuits

Combination Press based on… • • • • 16 “ modular reel to reel / sheet platform + auxiliaries Can handle paper, carton board, films, foils & label stocks with thicknesses of between 25-370 microns Litho UV / Conventional Screen UV and WB Flexo UV / Solvent / WB Gravure Solvent

Press prints offset litho, flexo, screen & gravure

-all interchangeable Re-register from unit 1 - offering versatility to reproduce significantly larger presses with multiple print stations

Ancillary On-Press Processes

De-Lam Re-lam UV Lamination Cold Foil Die cutting & sheeting

ISS line Print graphics (Nilpeter) Print conductive circuits / devices. Inks available for Flexo, Screen, Gravure, Litho Add components and integrate into packaging to create interactive products / smart packaging. (Offline / online equipment)
