2. INTRODUCTION
• Flexible electronics also known as flex
circuits ,is a technology for
assembling electronic circuits by
mounting electronic device 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

3. FABRICATION
TECHNOLOGY FOR FE
•Fabrication on sheets by batch processing
• 1. On a ridge carrier facing up and loose
•2. In a tensioning frame , facing up or
down
•3.In a frame facing down and loose
• Fabrication on web by roll to roll
processing
• Additive printing

4. FLEXIBLE CIRCUIT
BOARDS
•Flex circuits are made up
of flexible plastic substrate
usually polyimide ,
polyester or thin sheets of
glass

5. FLEXIBLE ELECTRONIC
COMPONENTS
•Electronic components such
as transistors are being made
from silicon nanomembrane
usually called TFT (Thin Film
Transistors)

6. EXAMPLES
Lithium ion flexible battery Non volatile memories

7. FLEXIBLE
DISPLAYS
Organic light emitting
diodes are normally used
instead of a backlight for
flexible displays

8. ADVANTAGES
•LIGHT WEIGHT
•SMALLER DIMENSIONS REQUIRED
•SPACE SAVING
•FOLDABLE AND BENDABLE
•INCREASWD CIRCUITARY DENSITY
•WIDE VIEWING ANGLE

9. DISADVANTAGES
•INITIAL INVESTMENT MAY BE
EXPENSIVE
•INTEGRATION OF COMPONENTS
WOULD BE CHALLENGE FOR ENGINEERS
•PRECISION MACHINES REQUIRED
•LIFETIME
•MANUFACTURING

10. 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 up to
2020 there would be huge
demand and preference will be
given to the flexible products in
market
