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 Non- Cleanroom 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 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 Die cutting & sheeting UV Lamination Cold Foil

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)

Print conductive tracks Example below Flexo silver 0.4 mm wide track printed using 15 CM3/M2 anilox Plate Kodak NX Evaluating Inks / Materials Drying / Curing Production speeds Sintering Measuring resistance Plate Recently printed trial for large volume application

Cross section of Silver 5µm Substrate PET

Analysis Equipment at CPI Material/ ink properties –Rheometer –Contact angle measurement Structural properties –Optical microscopes –Scanning Electron Microscope with Elemental analysis –Atomic Force Microscope –White light interferometer

DEK Screen Printer –for conductive ink & structural adhesives –print accuracy down to 10 microns Screen Printer

Pick and Place-component attachment Placement and attachment of components onto conductive adhesive or tape or print Able to position components of a range of sizes Pick and place equipment with low to medium volume focus and high flexibility of component types Placement accuracy of 35 microns

Adhesive Curing Cure to form electrical & structural connection between components and printed circuit/substrate Oven - air drying adhesive systems UV Curing - Radiation cure adhesive systems

Cut & Crease / Converting To convert smaller quantities of print into finished products and samples Esko digital cutting table –Cut & crease boxes –Kiss cut labels Trotec CO 2 Laser –Fine cutting –Engraving –Ablation of circuits

Summary CPI’s new ISS line opened in April 2012 Equipped with commercial print, packaging and electronics equipment Available for development, prototyping, scale up and pilot production projects
