In-molded resistive and shielding elements
View Patent ↗An article of manufacture having an in-molded resistive and/or shielding element and method of making the same are shown and described. In one disclosed method, a resistive and/or shielding element is printed on a film. The film is formed to a desired shape and put in an injection mold. A molten plastic material is introduced into the injection mold to form a rigid structure that retains the film.
1. An electromagnetic shield, comprising:
a film having a conductive ink shielding layer printed on a surface of said film; and
a plastic support structure surrounding at least a portion of the film, wherein the film is secured to the plastic support structure.
2. The electromagnetic shield of claim 1 , the surface of said film having an A-surface and a B-surface, wherein at least one of the A-surface and the B-surface of the film is secured to at least one of an A-surface and a B-surface of the plastic support structure.
3. The electromagnetic shield of claim 1 , wherein said film is in-between a top of the plastic support structure and a bottom of the plastic support structure.
4. The electromagnetic shield of claim 1 , wherein the film is secure to the plastic support structure to form a three dimensional object having a plurality of surfaces, the surfaces being at least one of a flat surface and a curved surface.
5. A resistive element, comprising:
a film having a conductive ink resistive layer printed on a surface of said film; and
a plastic support structure surrounding at least a portion of the film, wherein the film is secured to the plastic support structure.
6. The resistive element of claim 5 , the surface of said film having an A-surface and a B-surface, wherein at least one of the A-surface and the B-surface of the film is secured to at least one of an A-surface and a B-surface of the plastic support structure.
7. The resistive element of claim 5 , wherein said film is in-between a top of the plastic support structure and a bottom of the plastic support structure.
8. The resistive element of claim 5 , wherein the film is secured to the plastic support structure to form a three dimensional object having a plurality of surfaces, the surfaces being at least one of a flat surface and a curved surface.
