A method of making a printed wiring board (“PWB”) is disclosed. The PWB may be made by forming openings in a substrate. The substrate may be a dielectric substrate. The dielectric substrate may be at least partially uncured. A conductive sheet may be placed on one or both sides of the substrate to cover the openings. The substrate may be cured. The conductive sheet(s) may then be etched to form conductive tabs within the openings. The conductive tabs are free of dielectric material on both sides of the conductive tab. The conductive tabs may then be coupled to terminals of electrochemical cells to form a circuit as desired.

IC device assemblies including a power delivery bus board that is mounted to a primary PCB (i.e., motherboard) that further hosts a power-sink device and a power-source device. The bus board, as a secondary PCB, may be surface-mounted on a back side of the primary PCB opposite the power source and sink devices, which are mounted on the front side of the primary PCB. The bus board need only be dimensioned so as to bridge a length between first and second back-side regions of the primary PCB that are further coupled to a portion of the front-side pads employed by the power-sink device. The secondary PCB may be purpose-built for conveying power between the source and sink devices, and include, for example, short, wide traces, that may be formed from multiple heavyweight metallization layers.

A printed article is described. The printed article includes first and second sheets and a circuit board interposed between the first and second sheets. The circuit board supports a coin cell holder adjacent to the second sheet. The second sheet has a slit arranged to form a flap over the coin cell holder which is configured to allow a coin cell to be re-insertably removed from the coin cell holder.

A lighting unit is removably inserted into a pocket to create a light effect through use of a light effect material. The lighting unit has a PCB with a first side to which one or more LEDs and a battery are mounted. A clear potting material encloses the PCB, LEDs, and the battery and creates a transparent space proximate an inner surface of the light effect material which maintains the light effect material at a preselected distance from the LEDs so that light emitted from each light emitting die is dispersed by a plurality of dispersive elements in the light effect materials to create the light material viewing effect.

A battery connection module includes a plurality of bus bars provided on a battery stack in which a plurality of battery packs are assembled, and attached to electrodes of the battery packs, a flexible printed wiring board provided on the battery stack, and a first electronic component electrically connected to the flexible printed wiring board.

Aspects of the current subject matter relate to methods and system for protecting a battery cell and/or a /pack of multiple battery cells serving as a power source of a vaporizer device from developing a short-circuit in a vaporizer device. In one aspect, a vaporizer device is provided. The vaporizer device may include a power source including a battery and a power source lead extending outward from a distal end of the battery. The vaporizer device may further include a printed circuit board (PCB) electrically coupled to the power source via the power source lead extending outward from the battery. The vaporizer device may further include an insulator at least partially surrounding the power source lead. The insulator may be mechanically coupled to at least one of the power source and the PCB.

A flexible printed wiring board according to an aspect includes an insulating base film and a conductive pattern stacked on one surface side of the base film. The flexible printed wiring board further includes one or more square-shaped connecting terminals stacked over the conductive pattern with solder in between on one edge side of the conductive pattern. The connecting terminal is made of metal and includes a bent portion with both ends bent opposite to the base film. The connecting terminal includes a plated layer on an outer surface side of the bent portion.

A flexible printed wiring board according to an aspect includes an insulating base film, a conductive pattern disposed on one surface of the base film and including one or more land portions, and a solder resist layer disposed on one surface of the base film in a partial or any region excluding the one or more land portions, the solder resist layer having a CTI value of 200 V or more.

A biostimulator, such as a leadless cardiac pacemaker, having a flexible circuit assembly, is described. The flexible circuit assembly is contained within an electronics compartment between a battery, a housing, and a header assembly of the biostimulator. The flexible circuit assembly includes a flexible substrate that folds into a stacked configuration in which an electrical connector and an electronic component of the flexible circuit assembly are enfolded by the flexible substrate. An aperture is located in a fold region of the flexible substrate to allow a feedthrough pin of the header assembly to pass through the folded structure into electrical contact with the electrical connector. The electronic component can be a processor to control delivery of a pacing impulse through the feedthrough pin to a pacing tip. Other embodiments are also described and claimed.
