    • The present invention embeds passive components within a multilayer substrate used for mounting integrated circuits and other electronic components to form an electronic module or circuit board. During construction of the multilayer substrate, passive components are attached to an inside surface of a metallic foil layer. The inside surface of the metallic foil layer is then laminated to another metallic foil layer, such that the foil layers are parallel to but separated from each other. As such, the passive component is embedded within the multilayer substrate. Contacts are formed for the passive component by etching away portions of the foil layer on which the passive component resides. Electrical connections can be routed in the foil to effectively couple the passive component to a circuit formed on the multilayer substrate as desired. The embedded passive components can take various forms, such as capacitors, inductors, and resistors.
    • 本发明将无源部件嵌入用于安装集成电路和其他电子部件的多层基板中,以形成电子模块或电路板。 在多层基板的构造期间,无源部件附着到金属箔层的内表面。 然后将金属箔层的内表面层压到另一金属箔层上,使得箔层彼此平行但分开。 因此,被动部件嵌入在多层基板内。 通过蚀刻去除被动部件所在的箔层的部分,为无源部件形成触点。 电连接可以在箔中布线以有效地将无源部件耦合到根据需要在多层基板上形成的电路。 嵌入式无源器件可以采取各种形式,如电容器,电感器和电阻器。
