In one embodiment of the invention, a stacking element includes a printed circuit board (PCB) and a plurality of solder bumps. The PCB has a top side and a bottom side. The top side is attached to first pins of a first device. The plurality of solder bumps are on the bottom side and attached to upper areas of second pins of a second device to provide electrical connections between the first pins and the second pins.
Abstract:
The present invention relates to a method and to an arrangement for connecting a component, such as a chip (6), on a substrate (7) to a conductive surface of a carrier, such as an earth plane (10) on a printed circuit board (8) having a conductive layer (11) in a so-called compact design.
Abstract:
The invention relates to an electric component (surface mountable component) which can be mounted on the surface of a printed circuit board, and to a method of manufacturing said component. Such a component comprises a thin, electroconductive layer or stack of layers which is provided with end contacts and arranged on a support of an electrically insulating material. In accordance with the invention, the dimension of the layer or stack of layers in at least one direction parallel to the surface of the support is smaller than the dimension of the support in said direction, while leaving portions of the surface of the support clear on at least two sides of the layer or stack of layers, and end contacts for the layer or stack of layers are situated on the surface portions of the support which are free of this layer or stack of layers, the thickness of said end contacts being larger than the thickness of the layer or stack of layers. The method in accordance with the invention enables small-size electric components to be manufactured in which the end contacts form a reliable electric connection with the electroconductive layer or stack of layers of the component.
Abstract:
A surface mount package (10) to encapsulate one or more semiconductor devices (28) has a standoff (12) that maintains the thickness (D) of solder columns (26) bonding the package (10) to an external circuit (38). The standoff (12) either extends over or circumscribes a central portion (16) of the package base (14). To enhance the thermal performance of the standoff (12), a solderable layer (48) enhances soldering of the standoff (12) to the external circuit (38). In alternative embodiments, the standoff (12) contains a flange (58) having a plurality of apertures (62) useful for either mechanically locking an adhesive (34) or for enabling irradiation of an adhesive (34) by a light source. The standoff (12) may contain protrusions (64, 65) for alignment, strength or circuit (66) routing.

PROBLEM TO BE SOLVED: To mount a semiconductor element package on a circuit board without increasing a cost and without degrading electric performances of the semiconductor element package and the circuit board. SOLUTION: An interconnect board 20 interposed between a first circuit board 10 and a second circuit board 30 mounts the first circuit board 10 to the second circuit board 30. A metal plate 22 involved functions as a power supply layer or a ground layer electrically connected to a power supply terminal or a ground terminal of each of the first circuit board 10 and the second circuit board 30 through a first connection terminal 23-1 and a second connection terminal 23-2. A metal pile 24 electrically connects a signal terminal of the first circuit board 10 to the corresponding signal terminal of the second circuit board 30. The interconnect board 20 electrically connects the first circuit board 10 to the second circuit board 30, and an insulating layer 21 and the metal plate 22 function as a stiffener. Accordingly, stress caused due to deflection and warpage of the first circuit board 10 can be suppressed. COPYRIGHT: (C)2011,JPO&INPIT
