Abstract

See full text

A PCB for wireless power transfer includes an antenna and the antenna includes a coil. A method for manufacturing the PCB includes providing a prefabricated PCB, the prefabricated PCB including a PCB design and a first area and providing a first sheet of a conductive metal for the first area. The method includes applying an etch resistant coating on a coil area within the first area and laser cutting the first sheet within the coil area, based on a laser cutting path for a first plurality of turns for a first layer of the coil, the first geometry configured wireless power transfer. The method further includes substantially exposing the first sheet to an etching solution, the etching solution substantially removing first portions of the conductive metal from the substrate to define, at least, first turn gaps between at least two of the first plurality of turns.
