摘要:
The present invention is related to a mounting kit comprising a mother base, a son base and a connection unit. The mother base is disposed to a fixed object with a storage space to move up/down and/or turning left/right and fastened to a position of the fixed object. The son base is correspondingly connected to the storage space which permits the user to choose to move inward or outward and fastened to a position. The connection unit is correspondingly connected to the son base which to make up/down and or facing downward/upward adjustment and fastened to a position. Its front can be disassembled for fastening to the back of the display device or the back of the supporting object. Hence, the invention can steadfastly fasten different brands and different measurements of display devices to a fixed object (or its supporting rod), and adjust the best viewing angle for the user.

An exemplary method for manufacturing flexible printed circuit board is provided. A metal foil is supplied from a first feeding roller. The metal foil has a first surface and a second surface on two opposite sides of the metal foil. A first coverlay having a number of first openings defined therein is supplied from a second feeding roller and laminated on the first surface of the metal foil. Electrical traces are formed with the metal foil. A second coverlay having a number of second openings defined therein is supplied from a third feeding roller and laminated on the second surface of the metal foil. Each of the second openings registers with the respective first opening so that the electrical traces are exposed from the corresponding first and second openings. The method can improve quality and efficiency of manufacturing flexible printed circuit boards in a hollowed out form.

A substrate having single patterned metal layer applied in a package is provided. The substrate includes a first patterned dielectric layer, a patterned metal layer and a second patterned dielectric layer, wherein the patterned metal layer is embedded in the first patterned dielectric layer. Also, the top surfaces of the patterned metal layer and the first patterned dielectric layer lie in the same plane. At least part of the patterned metal layer are exposed from the holes formed on the lower surface of the first patterned dielectric layer, so as to form plural first contact pads for electrical connection downwardly. The second patterned dielectric layer, formed above the patterned metal layer and the first patterned dielectric layer, at least exposes part of the patterned metal layer to form plural second contact pads at the top surface of the patterned metal layer for electrical connection upwardly.

A substrate having single patterned metal layer includes a patterned base having at least a plurality of apertures, the patterned metal layer disposed on the patterned base, and a first surface finish layer. Parts of the lower surface of the patterned metal layer are exposed by the apertures of the patterned base to form a plurality of first contact pads for downward electrical connection externally, and parts of the upper surface of the patterned metal layer function as a plurality of second contact pads for upward electrical connection externally. The first surface finish layer is disposed at least on one or more surfaces of the second contact pads, and the first surface finish layer is wider than the second contact pad beneath. A package applied with the substrate disclosed herein further comprises at least a die conductively connected to the second contact pads of the substrate.

A chip package structure includes a substrate, a die, and a package body. The substrate includes a single patterned, electrically conductive layer, and a patterned dielectric layer adjacent to an upper surface of the electrically conductive layer. A part of a lower surface of the electrically conductive layer forms first contact pads for electrical connection externally. The patterned dielectric layer exposes a part of the upper surface of the electrically conductive layer to form second contact pads. The electrically conductive layer exposes the lower surface of the patterned dielectric layer on a lower periphery of the substrate. The die is electrically connected to the second contact pads, the patterned dielectric layer and the die being positioned on the same side of the electrically conductive layer. The package body is disposed adjacent to the upper surface of the electrically conductive layer and covers the patterned dielectric layer and the die.
