Abstract
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.
Claims19
A method of manufacturing a printed wiring board comprising:
- forming at least one opening through a dielectric substrate;
- applying a conductor sheet to at least one side of the dielectric substrate to cover the at least one opening with the conductor sheet;
- and
- removing at least a portion of the conductor in areas disposed over the at least one opening to form at least one conductive pad suspended over or within the opening.
A method of manufacturing a printed wiring board comprising:
- forming a plurality of openings through a sheet of woven fibers that are pre-impregnated with uncured epoxy;
- applying a layer of copper to both sides of the sheet;
- curing the sheet with elevated heat and pressure;
- and
- etching at least a portion of the copper in areas disposed over the openings to form at least one copper connector suspended over or within the opening.
A method of electrically connecting a plurality of battery cells comprising:
- forming a plurality of openings through an at least partially uncured dielectric substrate;
- applying copper to opposites sides of the substrate and covering the plurality of openings;
- curing the dielectric substrate;
- etching at least a portion of the copper in areas disposed over the openings to form at least one copper connector positioned within each of the plurality of openings;
- placing the at least one copper connector on top of a battery cell;
- and
- welding the copper connector to a terminal of the battery.
