Flexible Electronics PPT by Sourabh Kumar
- 1. Presentation on Flexible Electronics PRESENTED BY SOURABH KUMAR 13ECIEC008 B.TECH, EC, VIII SEM CITM COLLEGE SITAPURA
- 2. Outline: • Introduction to Flexible Electronics • Technologies and Integration Processes • Fabrication Technology • Flexible circuit board • Flexible electronic components • Manufacturing of flexible circuits & device • Material and thickness • Market Growth • Applications • Advantages and disadvantages • Reference & Conclusion
- 3. Introduction to Flexible Electronics • Flexible electronics, also known as flex circuits, is a technology for assembling electronic circuits by mounting electronic devices on flexible plastic substrates. • FLEXIBLE ELECTRONICS can actually be defined as the electronic devices which can be bent and stretched into any shape at any time.
- 4. Flexible Electronics A generic large-area electronic structure is composed of : Substrate Back-plane Front-plane Encapsulation
- 5. TECHNOLOGIES AND INTEGRATION PROCESSES Any manufacturable device has four essential characteristics: Superior and pre-specified performance, with reproducibility, uniformity, and reliability High yield to acceptable tolerance Simulations exist for both reverse engineering during development and right-first-time design Proven adequate in-service lifetime.
- 7. FABRICATION TECHNOLOGY FOR FLEXIBLE ELECTRONICS Fabrication on sheets by Batch Processing.. On a rigid carrier, facing up and loose; In a tensioning frame, facing up or down; In a frame, facing down and loose Fabrication On Web by roll-to-roll Processing Additive Printing
- 8. Flexible Circuit boards Flex circuits are made up of flexible plastic substrate usually polyimide, Polyester or thin sheets of glass
- 9. Flexible electronic components Electronic components such as transistors are being made from silicon nanomembrane usually called TFT’s(thin film transistors). Flexible resistors & capacitors structures are shown diagrammatically usually called thin flim resistors and thin flim capacitors
- 12. Flexible Displays Organic light-emitting diodes (OLEDs) are normally used instead of a back-light for flexible displays.
- 14. Manufacturing of flexible circuits & devices For the manufacturing of flexible electronics “Roll to Roll” (R2R) processing inkjet printing and soft lithography process is used. Steps of R2R processing
- 15. Layers materials and their thickness Base material or substrate 1.Flexible polymer flim 2. Polyethylene terephthalate 3. Thin glass sheet 12-125 µm Conductive path 1. Copper foil 2. Polyester 3. Graphene 200 nm
- 16. Market Growth • The market for flexible, printed, and organic large-area electronics is rapidly growing. Currently estimated at over $200M, the global market is expected to increase to a $800M market by 2020.
- 17. Applications Automotive field. Space crafts. Foldable displays. Military. Electronics Devices. Health Care Displays and Human- machine interaction Energy management and mobile devices Wireless systems Electronics Embedded in the living environment Flexible solar cells Flexible outwears
- 19. Stretchable Lithium ion battery Developed by University of llinois at Urbana
- 20. Flexible Devices
- 22. ADVANTAGES light weight Smaller dimensions required Space saving Foldable and bendable Increased circuitry density Wide Viewing Angle DISADVANTAGES Initial investment may be expensive Integration of components would be challenge for engineers Precision machines required Lifetime Manufacturing
- 23. Conclusion Flexible electronics in future will play a part in field of security, entertainment and may lead to innovative applications The demand for flexible electronic products at present may not be noticed but upto 2020 there would be huge demand and preference will be given to the flexible products in market
