These products are ideal for use as internal wiring of electronic devices.
Parallel multi-core electric wires in which rectangular conductors are aligned with uniform spacing and laminated with insulating tapes.
All of TOTOKU's flexible flat cables are lead-free products.
(Note) "LEAFCONN" is a registered trademark of TOTOKU INC.
It is as thin as a tree leaf, and the veins of the leaves look like conductors, which is the image of a key part that bring breath to the product.

Features
Our lineup includes "halogen-free flexible flat cables" as an ecological measure, and "gold-plated flexible flat cables" as a countermeasure against whiskers.
Standard flexible flat cables
- More economical than FPC.
- Excellent elastic behavior able to withstand repeated bending.
- Products with any desired length and number of cores can be easily produced.
- Connection is simple since the electric wire itself can also be used as a connector contact.
- Better heat dissipation than round wires, for larger available current capacity per unit of cross-section area.
- Can be bent to any desired shape for use.
- Small wiring space requirements, for improved mounting density.
Halogen-free flexible flat cables (for ecological measures)
- Contain no halogen flame retardants or antimony compounds.
- Various properties including flame resistance are the same as past LEAFCONN products which used halogen flame retardants.
Gold-plated flexible flat cables (for countermeasures against whiskers)
- Zero whisker generation to ensure reliability of connection.
- Excellent contact stability of connectors and other components.
- Outstanding corrosion resistance, making soldering possible.
Application
- Lead wires for interconnection of printed circuit boards in electronic devices such as printers, copiers, stereos, TVs, VTRs, telephones, and fax machines.
- Lead wires for connection between printed circuit boards and electronic components.
