    摘要: An embedded circuit board made without gas bubbles or significant internal gaps according to a manufacturing method which is here disclosed comprises an inner layer assembly, an embedded element, and first and second insulating elements. The inner layer assembly comprises a first main portion with opposing first and second surfaces, a first groove not extending to the second surface is positioned at the first surface. A first opening penetrates the second surface, and the first opening and the first groove are connected. The first groove carries electronic elements for embedment. The first insulating element covers the first surface and a surface of the embedded element away from the second surface. The second insulating element covers the second surface and extends into the first opening to be in contact with the embedded element.

    摘要: An embedded circuit board includes a flexible printed circuit board, a component, a conductive material, two adhesive layers, and two substrates. The flexible printed circuit board defines at least one cavity passing through the flexible printed circuit board. The flexible printed circuit board includes a base layer, a first conductive circuit layer formed on at least one surface of the base layer, and a protective layer formed on both sides of the base layer. The base layer and the first conductive circuit layer protrude into the cavity. The component is received within the cavity and abuts against the first conductive circuit layer protruding into the cavity. The conductive material is applied in a gap between the component and the first conductive circuit layer. The two substrates are adhered to the flexible printed circuit board by the two adhesive layers.
