For a long time now, flexible flat cables (FFCs) have found widespread use in the automotive and IT industries. Lamination and extrusion are the processes most commonly used for the production of FFCs today. The disadvantage of lamination is its extremely low production speed in conjunction with hygroscopic problems. Extrusion is unsuitable for the production of micro FFCs due to the high temperatures and pressures encountered in the extruder head: these make it impossible to maintain accurate geometrical dimensions and precise positioning.

As world market leader in coating equipment for optical fibres, Medek & Schörner has now developed a new pressureless cold process for the production of FFCs using UV cured resins , thus ensuring the perfect geometrical accuracy of the cable at high production speeds. The same procedure can also be employed inline with an extruder to position the individual flat cables accurately as they enter the extruder head.
