Abstract:
An electronic device including a substrate having opposing top and bottom surfaces is provided. A ground layer is disposed in the substrate. An electrically conductive chassis has a mounting surface to receive the bottom surface of the substrate and is in electrical contact with the ground layer by a ground stitch via. An electromagnetic shield is defined by the ground layer, the ground stitch via and the chassis to enclose the bottom surface of the substrate and protect the bottom surface from electromagnetic interference. A non-conductive cover is assembled to the substrate in tension so that an interior surface of the cover applies a force to the top surface of the substrate thereby ensuring the chassis maintains in electrical contact with the ground layer.
Abstract:
Described are a shielding case, a Printed Circuit Board (PCB) and a terminal device. The shielding case includes a first shielding case body (1) and a second shielding case body (2) that are interconnected, wherein the second shielding case body (2) at least partially covers the first shielding case body (1), and a heat storage material (3) is accommodated between the first shielding case body (1) and the second shielding case body (2).
