Abstract:
A method of making an optical fiber flexfoil, comprising the steps of:providing a base foil and a top foil,coating a top surface of the base foil and a bottom surface of the top foil with a pressure sensitive adhesive,applying optical fibers in predetermined paths to the coated top surface of the base foil to be bonded to the base foil by the pressure sensitive adhesive,placing the top foil at the top surface of the base foil to make the presentation sensitive adhesive at the bottom surface of the top surface come in contact at least with the optical fibers,removing air located between the base foil and the top foil, andafter removing the air, applying an evenly distributed hydrostatic pressure on the base foil and on the top foil for pressing the top foil and the base foil against each other to bond the top foil and the base foil to each other only by the pressure sensitive adhesive.
