Abstract:
Stacked arrays of components are disclosed. In one embodiment, a first and a second layer of components are electrically and mechanically coupled to an interposer with an encapsulated third layer of components disposed between the first and second layers. The first layer can be configured to attach the stacked array to a host printed circuit board. The interposer can couple signals between the components on the first and second layers.
Abstract:
Stacked arrays of components are disclosed. In one embodiment, a first and a second layer of components are electrically and mechanically coupled to a thin interposer disposed between the first and second layers. The first layer can be configured to attach the stacked array to a host printed circuit board. The interposer can insulate the components from one another and also couple signals between the components on the first and second layers. In one embodiment, the components in the first and second layers are passive components.
Abstract:
The described embodiment relates generally to the field of PCB fabrication. More specifically conductive spheres are used in a bonding sheet to enable inter-layer communication in a multi-layer printed circuit board (PCB). The conductive spheres in the bonding sheet can be used in place of or in conjunction with conventional electroplated vias. This allows the following advantages in multi-layer PCB fabrication: dielectric substrate layers made of varying types of material; PCBs with higher resilience to stress and shock; and PCBs that are more flexible.
Abstract:
A low profile, space efficient circuit shield is disclosed. The shield includes top and bottom metal layers disposed on the top of and below an integrated circuit. In one embodiment the shield can include edge plating arranged to encircle the edges of the integrated circuit and couple the top and bottom metal layers together. In another embodiment, the shield can include through vias arranged to encircle the edges of the integrated circuit and couple the top and bottom metal layers together. In yet another embodiment, passive components can be disposed adjacent to the integrated circuit within the shield.

Abstract:
A spring finger interconnection system can include a plug and a receptacle. In one embodiment, the plug can include spring finger contacts configured to carry electrical signals. The receptacle can include a cavity to receive the plug and the cavity can be constructed with printed circuit board fabrication techniques. In one embodiment, the cavity can be formed, at least in part, in a pre-impregnation layer and a first and a second layer can be disposed above and below the pre-impregnation layer to further form the cavity. In one embodiment, contacts can be arranged on the first layer to contact the spring fingers when the plug is inserted into the cavity. In another embodiment, contacts can be arranged on both the first and the second layers. In yet another embodiment, the cavity can be shaped to aid in contact-to-spring finger alignment when the plug is inserted in the cavity.
Abstract:
The described embodiments relate generally to electronic components and more specifically to a capacitor array that can increase component density on a printed circuit board and reduce a distance to a ground plane. An array of capacitors can be formed by coupling a group of capacitors on their sides interspersed with interposer boards. The resulting configuration can increase component density and reduce an amount of resistance and effective series inductance between a set of power decoupling capacitors and an integrated circuit.
