    Abstract: A method and structure are provided for implementing a column attach coupled noise suppressor for a solder column structure of the type used to join a substrate to a circuit card. The electrical noise suppressor structure includes a plurality of elongated through openings that are arranged in a predefined pattern. The elongated through openings have electrically conductive sidewalls and are electrically connected together. The predefined pattern of the elongated, electrically conductive through openings corresponds to a layout of solder columns. The solder columns are attached at one end to either a substrate or a circuit card and are inserted through the elongated through openings of the electrical noise suppressor structure, spaced apart from the electrically conductive sidewalls. Then the solder columns are attached at the other end to the other one of the substrate or circuit card.

    Abstract: A method, program product and apparatus include resistance structures positioned proximate security sensitive microchip circuitry. Alteration in the position, makeup or arrangement of the resistance structures may be detected and initiate an action for defending against a reverse engineering or other exploitation effort. The resistance structures may be automatically and selectively designated for monitoring. Some of the resistance structures may have different resistivities. The sensed resistance may be compared to an expected resistance, ratio or other resistance-related value. The structures may be intermingled with false structures, and may be overlapped or otherwise arranged relative to one another to further complicate unwelcome analysis.
