Abstract: A circuit apparatus includes at least one circuit feature formed from patterning a conductive sheet. The conductive sheet includes an irregular surface and a planarized surface. Conductive sheet roughness is minimized in first regions of the circuit apparatus and is maintained in second regions of the circuit apparatus. Selectively planarizing portions of the conductive sheet allows for the utilization of lower cost rougher conductive sheets. The planarized surface allows for increased signal integrity and reduced insertion loss and the irregular surface allows for increased adhesion and enhancing reliability of the circuit apparatus.

Abstract: Electronic circuits, electronic packages, and methods of fabrication are provided. The electronic circuit includes a multilayer circuit board, and a tamper-respondent sensor embedded within the circuit board. The tamper-respondent sensor defines, at least in part, a secure volume associated with the multilayer circuit board. In certain implementations, the tamper-respondent sensor includes multiple tamper-respondent layers embedded within the circuit board including, for instance, one or more tamper-respondent frames and one or more tamper-respondent mat layers, with the tamper-respondent frame(s) being disposed, at least in part, above the tamper-respondent mat layer(s), which together define the secure volume where extending into the multilayer circuit board. In certain embodiments, one or more of the tamper-respondent layers are divided into multiple, separate tamper-respondent circuit zones, with the tamper-respondent layers, including the circuit zones, being electrically connected to monitor circuitry within the secure volume.

Abstract: An electronic printed circuit board structure for mitigating conductive anodic filament growth. The structure includes at least two conductive layers and a dielectric layer sandwiched between the conductive layers. At least one hole extends through the dielectric layer, and a layer of nonconductive material covers the at least one hole, wherein the nonconductive material is glass-free. A conductive plate layer is disposed over the nonconductive material layer to form a via connection in the structure.

Abstract: The embodiments relate to a method for integrating a venting system in a circuit board. Three or more interconnected accesses (VIAs) are formed in a printed circuit board (PCB). The VIAs are interconnected by routing a bi-planar channel spanning through the VIAs. The channel includes at least two sections, including a first channel section at a first plane extending from the first VIA to the second VIA and a second channel section at a second plane extending from the second VIA to the third VIA. The first and second sections are at different planar levels.

Abstract: An electronic component includes a first trace configured to transmit a first signal and a second trace configured to transmit a second signal. The electronic component further includes a layer of conductive material separated from the first and second traces by a layer of insulative material. The electronic component further includes a first vertical wall formed in direct contact with the layer of conductive material. The electronic component further includes a second vertical wall formed in direct contact with the layer of conductive material. The second vertical wall is separated from the first vertical wall by a void, and the void extends between the first trace and the second trace.
