    摘要: A displacement compensating module is disclosed wherein a blocking article, such as a polyimide tape, is disposed between an epoxy composition and the back surface of a substrate and between the epoxy composition and the inner surface of a cap for blocking the movement of the epoxy composition into a gap area during the manufacture of the module. An electronic module comprises a substrate, an integrated circuit chip disposed on the substrate, a cap disposed over and enclosing the chip and the substrate, a heat dissipator disposed between the cap and the chip for carrying away the heat dissipated by the chip, and an epoxy composition secured to the back surface of the substrate for sealing the module, and specifically, the chip within the module from harmful external influences. The boundary of a gap is defined by the edge of the substrate and the inner surface of the cap. A blocking article, such as a polyimide tape, is disposed between the epoxy composition on one side and the back side of the substrate coupled with the inner surface of the cap on the other side for holding the epoxy composition external to the gap and preventing the epoxy composition from being disposed within the gap during the manufacture of the module. As a result, the cap is relatively free to move with respect to the substrate. Unnecessary distortion of the cap is minimized and resultant damage to the chips within the cap is avoided.
