Flexible printed circuit

Flexible Printed Circuit, Flexible printed circuit board, flexible printed circuits General Description Single and double-sided flexible circuits are extremely cost effective interconnection media for low to high volume applications. Benefits:1. High reliability 2. Space and mass saving 3. Total repeatability 4. 3-D packaging system 5. Cost reduction 6. Improved current carrying capability 7. Improved heat dissipation 8. Light weight 9. Mechanical strength 10. Excellent in dynamic applications Materials/Applications1. Polyester - a low cost dielectric film. Lower temperature performance capability, solderable with care. Automotive, communication, consumer and similar highly cost conscious applications. 2. Polyethylene naphthalate (PEN) - an intermediate cost and performance option which can be soldered using conventional tin/lead alloys. Automotive, communication, consumer, computer and other applications. 3. Polyimide - high reliability, high performance material with good thermal and mechanical properties. Numerous applications from automotive to aerospace. 4. EMI/RFI and cross-talk shielding can be achieved by the use of silver loaded polymer inks. 5. Surface finishes - tin/lead, nickel/gold, immersion gold and OSP.
