IN-MOLD COIL REPEATER ASSEMBLY FOR MOBILE DEVICE CASE

A method of constructing a mobile device case includes placing a coil repeater assembly on pedestal members of a mold section, the repeater assembly including a wireless charging repeater circuit and a substrate, assembling a mold using the mold section to form a mold cavity, the cavity defining surfaces of the case body, injecting into the mold cavity heated thermoplastic material which flows around the repeater assembly, and removing the mold, the wireless charging repeater circuit having an inductive coil disposed on a surface of the substrate and a capacitor electrically coupled to ends of the coil. The wireless charging repeater circuit excludes electrical connection to an active component that supplies power. The coil repeater assembly is located within the case body such that, when the mobile device case is attached to a mobile device, the inductive coil is located proximate to a wireless charging coil in the mobile device.
