Abstract
Abstract A novel circuit board and method of fabricating such, and a novel combination of a circuit board with batteries in a battery pack and assembly method are disclosed herein. The circuit board is connectable by welding or soldering of integral tabs of the circuit board metal layer to the battery terminals. The circuit board includes at least one, and preferably two, insulator sheets and a metal layer laminated between the insulator sheets in sandwich fashion. The metal layer has integral tabs extending in pairs into openings of the metal sheet, coincident with openings in the insulator sheets. The tabs are generally coplanar with the remainder of the metal sheet and readily accessible, for example, by a spot welder, through the openings. The metal and insulator components to form the circuit board are aligned with each other. The laminted board assembly is postpunched to remove sections of the metal layer, along with corresponding sections of the insulator sheets, to result in the desired circuitry.
