A shield can for an electronic eyewear device is described that reduces RF signals emanating from the electronic eyewear device. The shield can is attached to a ground plate of the electronic eyewear device using leaf springs on a side of the shield can. The leaf springs do not add to the stack-up thickness of the shield can assembly and provide a balanced force against the ground plate. The shield can is attached to a printed circuit board and encompasses radio frequency (RF) electronic components to prevent RF signals emanating from the RF electronic components. The leaf springs have a pair of fingers providing the balanced mechanical point force. A conductive pressure sensitive adhesive is also provided to secure a top surface of the shield can to the ground plate along with a thermal paste.
Electronic eyewear device, comprising:
A shield can configured to be disposed between a printed circuit board (PCB) having electronic components and a ground plate, the shield can having a leaf spring including a protrusion biased to engage the ground plate when the shield can is coupled to the ground plate, wherein the shield can is configured to reduce emanation of radio frequency (RF) signals generated by the electronic components from within the shield can.
A method of using an electronic eyewear device having a ground plate, a printed circuit board (PCB) having electronic components, a head-mounted frame supporting the ground plate and the PCB, a shield can disposed between the ground plate and the PCB, and a leaf spring having a spring arm extending from the shield can and having a protrusion engaging the ground plate, wherein the leaf spring has a spring arm biasing the protrusion against the ground plate, the method comprising:
A method of coupling a shield can between a printed circuit board (PCB) having electronic components and a ground plate, the shield can having a leaf spring extending from the shield can between the PCB and the ground plate, comprising:
