SUPPORT PART FOR A COMPONENT OF A SECURED ELECTRONIC DEVICE
A support part for an LCD display module of an electronic device includes at least one element for receiving a press device for pressing a dummy key. The support part at least one attachment element for securing the part to a printed circuit board of the electronic device such that the press device is compressed between the support part and the printed circuit board.
PRINTED CIRCUIT BOARD
A printed circuit board includes a circuit layer and a ground layer disposed above the circuit layer. The ground layer includes ground layer sections each having metal members, arranged in parallel in one direction on a plane. Areas of the metal members of adjacent ground layer sections are different from each other.

OVERMOLDED ELECTRONIC MODULE WITH AN INTEGRATED ELECTROMAGNETIC SHIELD USING SMT SHIELD WALL COMPONENTS
An electronic module with an integrated electromagnetic shield using surface mount shield wall components has been disclosed. Each surface mount shield wall component provides side shielding of the circuitry within the overmolded electronic module and provides an exposed conductive shield wall section to which a top conductive shield can be applied. By including the shield structure as part of the overmolded electronic module, the need for a separate shield and separate process steps for installing the separate shield can be eliminated. Each surface mount shield wall component comprises a non-conductive portion that provides stability during a reflow soldering process, but at least a sacrificial portion of the non-conductive portion can be removed to reduce the amount of area occupied by the overmoldable shield structure.
PCB PAD FOR SMT PROCESS
A PCB pad for a SMT process is combined on a PCB. The PCB pad includes an insulation body and a metal reflow portion disposed on the insulation body. The metal reflow portion is located on the side of the insulation body adjacent to the PCB. The metal reflow portion is not electrically connected with the PCB. Thus, the PCB pad may support electronic components of the PCB and prevent the electronic components from being damaged by an external pressure.
DUMMY ELECTRONIC COMPONENT
An example device includes a planar circuit board with a first surface and a second surface opposite the first surface, an electrical circuit on at least one of the first surface or the second surface, and at least one dummy electronic component mounted on the first surface. The electrical circuit includes at least one electronic component. The dummy electronic component is electrically isolated from the electrical circuit. The dummy electronic component has a protrusion from the planar circuit board that is greater than protrusion of each of the at least one electronic component of the electrical circuit.
