    • Connection elements which, for example, may be used to facilitate interconnection to and stacking of electronic assemblies or may include an elongated conductive core, such as a wire or a hollow tube structure, coated with a layer of elastomeric material containing conductive particle such that the elastomeric material is conductive at least when compressed. The substrates of multi-chip modules (MCMs) have electrical connection sites in the form of metal-lined channels in the substrate edges, and the connection elements are pressed into the channels. Separate compression or clamping elements may be employed to enhance conductivity, as well as to facilitate external connections. The elongated conductive core may take the form of a hollow tube structure which may be expanded under internal pressure to compress the layer of elastomeric material. The compression elements may take the form of printed circuit boards. In alternative embodiments the connection elements may be clamped between conductive channels of side-by-side substrates or between opposed conductive channels of stacked substrates.
    • 连接元件例如可用于促进电子组件的互连和堆叠,或者可以包括细长导电芯,例如线或中空管结构,涂覆有包含导电颗粒的弹性体材料层,使得 至少在压缩时弹性材料是导电的。 多芯片模块(MCM)的基板在基板边缘中具有金属衬里通道形式的电连接位置,并且连接元件被压入通道中。 可以使用单独的压缩或夹紧元件来增强导电性,并且便于外部连接。 细长导电芯可以采取中空管结构的形式,其可以在内部压力下膨胀以压缩弹性体材料层。 压缩元件可以采用印刷电路板的形式。 在替代实施例中,连接元件可以被夹持在并排衬底的导电沟道之间或层叠衬底的相对的导电沟道之间。
