A device for inductively charging an electronic accessory includes a first portion, a second portion, and a spacer. The first portion includes a first transmission coil in a first plane where the first transmission coil is configured to generate a first magnetic field, and the second portion includes a first transmission coil in a second plane where the second transmission coil is configured to generate a second magnetic field. The spacer is positioned between the first transmission coil and the second transmission coil and between the first plane and the second plane. The spacer material magnetically insulates the second transmission coil from the first magnetic field.

The trackpad assemblies described herein maintain minimum overall stiffness, weight, and cost requirements of a trackpad assembly, while permitting a decrease in trackpad assembly thickness as compared to conventional trackpad assemblies. The trackpad assemblies may include one or more of a four-layer PCB, structural adhesives, a structural PCB stiffener, and a structural shield assembly. These stiffening features permit increasingly thinner trackpad assemblies and associated computing devices.
