Abstract

The present invention is systems for and methods of producing droplet actuator substrates using web coating processes and web-like processes that are suitable for volume manufacturing. In one example, a gap coating system of the present invention uses a Mayer rod for applying an amorphous fluoropolymer coating to a continuous web of laminate, wherein the laminate may be used for forming droplet actuator substrates. In another example, a gap coating system of the present invention uses a Mayer rod for applying an amorphous fluoropolymer coating to a continuous feed of discrete laminate parts. In yet another example, a gap coating system of the present invention uses a “knife-over-roll” coating technique for applying an amorphous fluoropolymer coating in a web coating process. In yet another example, a rotary die cutting system of the present invention uses a rotary die cutter for cutting laminates that are used for forming droplet actuator substrates. In yet another example of the present invention, a slot die coating system uses a slot die for applying an amorphous fluoropolymer coating to a web of laminate. In yet another example of the present invention, a slot die coating system uses a slot die for applying an amorphous fluoropolymer coating to a continuous feed of discrete laminate parts. In still another example of the present invention, a curtain coating system is used for applying an amorphous fluoropolymer coating to laminate in a web coating process or alternately to a continuous feed of discrete laminate parts.
