Abstract
A printed circuit board (PCB) with visible circuit includes a circuited substrate, a first and second release films, and a first and second optical clear adhesive (OCA) layers. The first and second release films are pressed onto and are adhered to two opposite surfaces of the circuited substrate via the first and second OCA layers respectively, and the first and second OCA layers are made of polymethyl methacrylate (PMMA).
Claims16
A printed circuit board (PCB) with visible circuit, comprising:
- a circuited substrate;
- and
- a first and second optical clear adhesive (OCA) layers deposited on two opposite surface of the circuited substrate
- wherein the first and second OCA layers are made of polymethyl methacrylate (PMMA).
A method for making and using a PCB with visible circuit, the method comprising:
- providing a circuited substrate;
- providing two adhesive tapes, each of which comprises a release film and a layer of optical pressure sensitive adhesive applying on the release film;
- pasting the two adhesive tapes onto two opposite surfaces of the circuited substrate using the layer of optical pressure sensitive adhesive which is mainly comprised of PMMA;
- pressing the adhesive tapes and tearing off the release films to cause the layers of optical pressure sensitive adhesive entirely remaining on the circuited substrate;
- providing two electronic modules;
- and
- adhering the electronic modules to the circuited substrate via the layers of optical pressure sensitive adhesive.
