Abstract
A flexible laminate electronic device includes a flexible substrate that includes electrical connections between electronic components attached to the flexible substrate. A first flexible additive layer includes apertures, wherein at least one of the one or more electronic components is aligned in one of the apertures. A subsequent flexible additive layer is disposed over the first flexible additive layer and aligned around respective portions of the electronic components protruding above the first flexible additive layer. A flexible cover layer is placed over the subsequent flexible additive layer.
Claims21
A flexible laminate electronic device comprising:
- a flexible substrate comprising a flexible circuit electrically connecting a plurality of electronic components attached to the flexible substrate;
- a first flexible additive layer on the flexible substrate and comprising apertures, wherein each of the plurality of electronic components are aligned in a respective aperture of the apertures and wherein a top surface of the first flexible additive layer is flush with a top surface of each electronic component of a first set of the plurality of electronic components;
- a subsequent flexible additive layer on the first flexible additive layer and covering the first set of the plurality of electronic components, the subsequent flexible additive layer comprising apertures aligned around respective portions of a second set of the plurality of electronic components protruding above the first flexible additive layer from the flexible substrate, wherein a thickness of the subsequent flexible additive layer corresponds to a difference between a thickness of a second set of the plurality of electronic components and a thickness of the first flexible additive layer;
- and
- a flexible cover layer on the subsequent flexible additive layer and covering the plurality of electronic components.
A flexible electronic device, comprising:
- a flexible substrate comprising a flexible circuit electrically connecting a plurality of electronic components;
- a first flexible additive layer on the flexible substrate and comprising apertures, the first flexible additive layer comprising a first thickness, wherein a first electronic component of the plurality of electronic components is aligned with a first aperture of the apertures and wherein a top surface of the first flexible additive layer is flush with a top surface of a second electronic component of the plurality of the electronic components;
- a second flexible additive layer on the flexible substrate comprising apertures, the second flexible additive layer having a second thickness, wherein the first electronic component and the first aperture are both aligned with a second aperture of the second flexible additive layer's apertures;
- and
- a flexible cover layer on the second flexible additive layer, wherein
- a sum of the first thickness and the second thickness corresponds to a height of the first electronic component of the plurality of electronic components, and
- a thickness of the flexible electronic device at a location overlapping the first electronic component equals a thickness of the flexible electronic device at a location overlapping the second electronic component.
