Abstract:
A circuit layer manufacturing method is applied to a portable computer. The portable computer includes a front bezel, a display module, and a back cover. The front bezel is connected to the back cover for containing the display module. The front bezel includes a metal portion. The metal portion has a flat region corresponding to a side of the back cover. The circuit layer manufacturing method includes forming at least one control circuit layer assembly on the flat region, grounding the control circuit layer assembly to the flat region, and forming a protection layer on the control circuit layer assembly. The control circuit layer assembly includes an insulation layer and a control circuit layer. The control circuit layer is electrically connected to the display module. The insulation layer is formed between the control circuit layer and the flat region for being alternately stacked with the control circuit layer.
Abstract:
A pre-molded cavity 3D packaging module with layout is disclosed. The 3D packaging module includes a pre-molded cavity. A wall and a vertical plane of the pre-molded cavity form an inclined angle of more than 3°. An intersecting region between a bottom and a sidewall of the 3D packaging module has a curved profile to facilitate smooth circuit layout.
Abstract:
A configuration in which a stand-alone plug connector is directly fitted to the wall of a product case, and in the fitting state of the stand-alone plug connector, the contact part of a contact comes in contact with the contact part of a wiring pattern conductive path exposed on the surface of a fit connecting hole, and the electrical connection of a signal transmitting medium can be performed in a simple configuration.
Abstract:
An antenna shape can be inked onto a thin film and then the thin film can be shaped to form a three dimensional (3D) flex-film. The 3D flex-film can then be integrated into a carrier using conventional molding processes. The resultant housing includes a carrier that supports the 3D flex-film on an inner or outer surface of the carrier. The resultant housing thus allows for improved integration of an antenna with a housing so as to provide a more desirable housing for devices that can benefit from the corresponding antenna, such as, but not limited to, mobile devices.
Abstract:
There is provided a mobile communication terminal case including: a case body of a mobile communication terminal having a first surface and a second surface opposite to the first surface, and a via hole formed through the first surface and the second surface; a conductive pattern provided on the first surface of the case body; a carrier film provided on the first surface of the case body to cover the conductive pattern; and conductive epoxy filling the via hole and having one end thereof in contact with the conductive pattern.
Abstract:
