Electronic device with structural layer

1. A device comprising:

a structural layer that comprises a first side surface, an opposing, second side surface, an opening, and connectors;

a first glass-reinforced epoxy circuit board mounted to the first side surface of the structural layer;

a second glass-reinforced epoxy circuit board mounted to the opposing, second side surface of the structural layer;

components wherein the components comprise a processor, memory operatively coupled to the processor, a flexible pouch lithium-ion battery, and a display operatively coupled to the processor, wherein the flexible pouch lithium-ion battery is disposed at least in part in the opening of the structural layer and operatively coupled to the processor, the memory, and the display;

a housing material supported by the structural layer wherein the housing material comprises couplings that couple directly to the connectors of the structural layer that transfer force applied to the housing material to the structural layer to protect the flexible pouch lithium-ion battery from the force applied to the housing material; and

display glass wherein the display glass forms, at least in part, a first side of the device, wherein the housing material forms, at least in part, a second, opposing side of the device, and wherein a thickness of the device between the first side and the second, opposing side is less than 10 mm.
