Flexible Flat Cable

LEAFCONN

It is the best product for internal wiring of electronic equipment.

This is a parallel multicore wire made of rectangular conductors arranged at regular intervals and laminated with insulating tape.
All of our flexible flat cables are lead-free.
(Note) “LEAFCONN” is a registered trademark of TOTOKU INC.

Processing type	Bending processing double-sided tape pasted punching Shield processing etc.

Features

The lineup also includes a "halogen-free flexible flat cable" as an environmental measure, and a "gold-plated flexible flat cable" as a whisker-proof measure.

Standard flexible flat cable

It is more economical than FPC.
It is highly flexible and can withstand repeated bending.
Products of any length and number of cores can be easily manufactured.
Connections are easy because the wire itself can also be used as a connector contact.
It has better heat dissipation than round wire and can have a larger current capacity per unit cross-sectional area.
It can be bent into any shape.
Wiring space is small and packaging density is improved.

Halogen-free flexible flat cable (for environmental protection)

Contains no halogen flame retardants or antimony compounds.
The properties, including flame retardancy, are the same as those of Leaf Con made using conventional halogen flame retardants.

Gold-plated flexible flat cable (for whisker prevention)

There are no whiskers, ensuring connection reliability.
Excellent contact stability for connectors, etc.
It has excellent corrosion resistance and can be soldered.

Gold-plated flexible flat cable

Shield type flexible flat cable

Use

Lead wires for connecting printed circuit boards of electronic devices such as printers, copiers, stereos, TVs, VTRs, telephones, and fax machines.
Lead wire for connection between printed circuit board and electronic components
