Abstract: Structures that implement three-dimensional (3D) conductive material (e.g., copper) in printed circuit boards (PCBs) are disclosed. 3D (three-dimensional) conductive material may include trenches and/or buried vias that are filled with conductive material in the PCBs. Trenches may be formed in build-up layers of a PCB by overlapping multiple laser drilled vias. The trenches may be filled with conductive material using electroplating process(es). Buried vias may be formed through the core layers of the PCB by mechanical drilling. The buried via may be filled with solid conductive material using a combination of electroless plating and electrolytic plating of conductive material. Various PCB structures are disclosed that implement combinations of these trenches and/or these buried vias filled with conductive material.

Abstract: Printed circuit boards (PCB) used to mechanically and electrically connect electrical components within an electronic device. Thin printed circuit boards (PCB) may be desirable to manufacturers and users of electronic devices. Accordingly, a process for manufacturing a printed circuit board may involve manufacturing a thin bilayer dielectric. The process may involve applying a first non-conductive layer to a metal substrate, and curing the first non-conductive layer to a C-stage resin layer that is fully cross-linked layer in a clean environment. In turn, a B-stage layer that is partially cured may be applied to the C-stage resin layer. Using a hot press, one or more metal traces may be pressed onto the B-stage layer. The B-stage resin layer may be fully cross-linked and integrated with the C-stage resin layer after lamination of the one or more metal traces and the B-stage resin layer.

Abstract: An item may include fabric having insulating and conductive yarns or other strands of material. The conductive strands may form signal paths. Electrical components can be mounted to the fabric. Each electrical component may have an electrical device such as a semiconductor die that is mounted on an interposer substrate. The interposer may have contacts that are soldered to the conductive strands. A protective cover may encapsulate portions of the electrical component. To create a robust connection between the electrical component and the fabric, the conductive strands may be threaded through recesses in the electrical component. The recesses may be formed in the interposer or may be formed in a protective cover on the interposer. Conductive material in the recess may be used to electrically and/or mechanically connect the conductive strand to a bond pad in the recess. Thermoplastic material may be used to seal the solder joint.
