摘要:
A resilient electrical connector assembly (100) includes a base PCB and stacked layers of interconnected resilient conductive structures where each structure has at least two resilient conductive strips (115, 130, 145) and at least two conductive contacts (105, 110, 135, 140, 150, 155, 160, 165). One contact is integrated with a conductive path on the base PCB (105, 110) and another contact pad (160, 165) is positioned to establish a conductive path with a target PCB when the latter is mounted parallel to the base PCB. The resilient conductive strips flex due to a compressive force exerted between the base PCB and target PCB on the stacked layers. The resilient conductive structures are formed by depositing metal to sequentially form each of the stacked layers with one contact being initially formed in engagement with the conductive path on the base PCB.

A related method of manufacture is presented.

A sub-component circuit board may be electrically and mechanically connected to a higher order circuit board using one or more leads extending from a lead frame embedded in the sub-component circuit board. The sub-component board is produced as a layered assembly with the embedded lead frame at the core. One or more dielectric layers and one or more circuitry layers are provided over the lead frame and then bonded using heat and pressure. Apertures in the dielectric and circuitry layers define a perimeter of the circuit board where the leads of the lead frame are exposed. The lead frame connects to the circuitry layer(s) using plated vias.

The present invention relates to polymer patterns of various shapes formed using modifications of means and methods used in the prior lithography process, and the metal film patterns, metal patterns and plastic molds using the polymer patterns, as well as methods of forming these patterns and molds. The method of forming the polymer patterns comprises the steps of: (a) depositing a photosensitive polymer on the substrate to form a polymer film; (b) placing a photomask on the polymer film; and (c) irradiating the polymer film with a light moving in random direction through the photomask, so as to form at least one pattern which is concave from the surface of the polymer film in a direction perpendicular to the substrate and extends in a direction parallel to the substrate. The inventive polymer patterns have at least one pattern which is concave from the surface of the polymer film in a direction perpendicular to the substrate and extends in a direction parallel to the substrate. The vertical cross-section of the concave patterns has at least one curved surface.
