Impedance Controlled FFC

As electronic devices demand higher digital serial data transmission rate, recent development of serial I/O interface accelerates in tandem with an increasing need for high performance Flexible Flat Cable (FFC) to control components/parts cost. At higher serial data speeds, ability to maintain Signal Integrity (Quality) becomes critical through impedance control and matching.

Ventura V-Flex ® High Performance, Cost Effective Impedance Controlled FFC utilizes our company's proprietary V-Flex 'Selective Shielding FFC'TM method employing both Shielding and Controlled Capacitance to achieve the required characteristic impedance to attain the required spec. of serial data transfer speed. Our R&D team utilises the premier Tektronix Digital Serial Analyser and high performance Agilent Pattern Generator in aid to design and test of FFC's impedance verifying and conforming to stringent product specifications.


  • Minimize the use of expensive shielding material (up to 50%) to achieve Impedance Matching
  • Very competitive cost FFC while improving/maintaining existing EMI & ESD performance
  • Highly customizable to meet various impedance design specification
  • Conformance to various High Speed Serial Data Link Standard e.g. USB 2.0 & 3.0


  • Audio & Video Entertainment System
  • Blue-Ray Player
  • Optical Drive
  • Game Consoles
  • Smartphone/Tablet & Laptop PC
  • Laser/Inkjet Printers/Scanner
  • Mobile Devices utilizing serial I/O technologies
  • Others
