    摘要: A method, structure, and method of design relating an electrical structure that includes a metal voltage plane laminated to a dielectric substrate. A determination is made as to where to place an opening for venting gases generated during fabrication of the dielectric laminate. An identification is made of a problematic opening in the metal voltage plane that is above or below a corresponding metal signal line within the dielectric laminate, such that an image of a portion of the corresponding metal signal line projects across the problematic opening. An electrically conductive strip is positioned across the problematic opening, such that the strip includes the image. In fabrication, the dielectric substrate having the metal signal line therein is provided. The metal voltage plane is laminated to the dielectric substrate. The opening in the metal voltage plane is formed such that the strip is across the opening and includes the image.

    摘要: A computer-implemented method provides an elastic modulus map of a chip carrier of a flip chip package. Design data including dielectric and conductive design elements of each of vertically aligned sub-areas of each of the layers of the chip carrier are modeled as springs to provide the elastic modulus map. Determining the elastic modulus of the sub-areas of the chip carrier identifies probable mechanical failure sites during chip-join and cools down of the flip chip package. Modifying a footprint of solder bumps to the chip carrier reduces stresses applied to the identified probable mechanical failure sites. Modifying the chip carrier design to reduce a stiffness of sub-areas associated with identified probable mechanical failure sites also reduces stresses from chip-join and cool-down.
