Injection molded control panel with in-molded decorated plastic film
View Patent ↗Provided are systems and methods for a control assembly including: a first film that is in-molded that includes decorative graphics, a front surface and a rear surface; and a second film molded to the rear surface of the first film having a printed circuit that includes sensors, control circuits and interconnects and a front and rear surface.
1. A method comprising:
printing a first film and forming, trimming and applying decorative graphics to the first film;
printing a second film and forming, trimming and placing a printed circuit frame on the second film;
mounting components of a printed circuit into the printed circuit frame and programming and testing the printed circuit on the second film;
placing the first and second film together in a mold and injecting the mold with molding resin between the films to form a resin core; and
inspecting the finished panel and packaging and shipping the finished panel once it has been tested,
wherein mounting components of a printed circuit into the printed circuit frame and programming and testing the printed circuit on the second film further comprises:
applying conductive silver epoxy aligned to component mounting pads;
dispensing glue at every component location to insure solid bonding with the second film;
placing components either manually or using conventional automated pick-and-place robotic placement equipment; and
curing conductive epoxy and glue at a manufacturer's recommended time and temperature if required.
2. The method of claim 1 , wherein a process used to print the first and second film and to mount the printed circuit to the second film comprises silkscreen, offset, flaxo, digital, gravure, sheet methods, roll to roll methods, and any combination of the listed.
3. The method of claim 1 , wherein a process used to form the first and second film comprises hydroform, high pressure forming, thermoforming, trimming using 2D or 3D trim tools, laser cutting, digital knife methods.
4. The method of claim 1 , wherein the process used to mount the printed circuit on the second film include PCB mounting methods, FPC mounting methods and adhesion.
5. The method of claim 1 , wherein printing the first film and forming, trimming and applying a decorative application to the first film further comprises:
depositing a film substance, the film substance comprising plastic, wood veneer, flocked products, leather, denim, pseudo suede synthetic imitations;
depositing a decoration film substance, the decoration film substance comprising plastic, wood veneer, flocked products, leather, denim pseudo suede synthetic imitations, metal, anti-microbial materials, anti-scratch hard-coat materials, mar-resistant coated materials, and texture treatments of finishes.
6. The method of claim 1 , wherein printing a second film and forming, trimming and placing a printed circuit frame on the second film further comprises:
depositing a film substance, the film substance comprising plastic, wood veneer, flocked products, leather, denim, pseudo suede synthetic imitations.
7. The method of claim 1 , wherein placing the first and second film together in a mold and injecting the mold with molding resin further comprises:
cutting holes in the printed circuit of the second film; and
shooting resin through the cut holes.
8. The method of claim 1 , wherein the first and second film comprises: in-molded decorated film, in-molded flexible film circuits, printed silver circuits, printed copper circuits, Indium Tin Oxide (ITO), and Polydioctyl-bithiophene (PDOT).
9. The method of claim 1 , wherein the components to be mounted comprise: in-mold capacitive switches, printed sensors, transparent or opaque touch-screen sensors, in-mold LED lighting, in-mold light guides to control and direct molded in LEDs, in-molded and normally printed: resistors, OLEDs, capacitors, transistors, antennas integrated with the printed circuit, component sensors, and camera lenses.
