Thick copper COF

Thick copper COF

We have a lineup of COF for cable applications for the purpose of passing signals and current.

The minimum wiring pitch can be up to 0.150mm.

(Please consult with us for finer requirements)

Stiffener can be attached to the connector insertion part.

You can freely choose the product size with a maximum width of 52 mm and a maximum length of 110 mm.


The conductor thickness is thicker than normal COF to lower the resistance for current flow. (8→18μm thickness)

Thick copper can be used not only for cable applications, but also for substrates for other applications that require current support.
