Abstract:
A circuit structure that has a high rigidity, has high cooling performance for an electronic component, and can reduce electrical resistance between the electronic component and a bus bar. The circuit structure has a circuit board, bus bars, a binding material, metal chips, and electronic components. The circuit board has opening portions that penetrate in the thickness direction. The bus bars are overlaid on the circuit board. The binding material is interposed between the circuit board and the bus bars and binds them. The metal chips are arranged inside the opening portions and also placed on the bus bars. The metal chips each have a top face, which is located in approximately the same plane as an opening end face of an opening portion, and a bottom face, approximately the entire surface of which is joined to a bus bar. The electronic components are soldered to the circuit board and the top faces of the metal chips.
Abstract:
A suspension board with circuit includes a metal supporting board, a base insulating layer disposed at one side in a thickness direction of the metal supporting board, and a conductor layer disposed at one side in the thickness direction of the base insulating layer and including a connecting terminal electrically connected to a slider. The base insulating layer has a terminal region, when projected in the thickness direction, overlapped with at least the connecting terminal and a circumferential region not overlapped with the terminal region and around the terminal region, and the thickness of the terminal region is thicker than that of the circumferential region.
