摘要： A method of attaching an integrated circuit (IC) package to a printed circuit board (PCB) with a set of direct current (DC) blocking capacitors includes: applying a conductive attachment material to a first set of attachment pads located on a first planar surface of the IC package; aligning the set of DC blocking capacitors in accordance with corresponding positions of the first set of attachment pads; attaching the set of DC blocking capacitors to the IC package by: positioning the aligned set of DC blocking capacitors so that a first surface of a first DC blocking capacitor of the set of DC blocking capacitors is adjacent to a corresponding attachment pad of the first set of attachment pads; and connecting the conductive attachment material to the IC package and to the first surface of the first DC blocking capacitor to create an IC package assembly.

摘要： An electronic system can be used to monitor temperature. The electronic system can include a characterized dielectric located adjacent to a plurality of heat-producing electronic devices. The electronic system can also include a leakage measurement circuit that is electrically connected to the characterized dielectric. The leakage measurement circuit can be configured to measure current leakage through the characterized dielectric. The leakage measurement circuit can also be configured to convert a leakage current measurement into a corresponding output voltage. A response device, electrically connected to the leakage measurement circuit can be configured to, in response to the output voltage exceeding a voltage threshold corresponding to a known temperature, initiate a response action.

摘要： A conductor on glass security layer may be located within a printed circuit board (PCB) of a crypto adapter card or within a daughter card upon the crypto adapter card. The conductor on glass security layer includes a glass dielectric layer that remains intact in the absence of point force loading and shatters when a point load punctures or otherwise contacts the glass dielectric layer. The conductor on glass security layer also includes a conductive security trace upon the glass dielectric layer. A physical access attempt shatters a majority of the glass dielectric layer, which in turn fractures the security trace. A monitoring circuit that monitors the resistance of the conductive security trace detects the resultant open circuit or change in security trace resistance and initiates a tamper signal that which may be received by one or more computer system devices to respond to the unauthorized attempt of physical access.

摘要： A lane within a processor bus that communicatively connects a transmitter and a receiver is dynamically assigned as a clock lane. The clock lane subsequently transmits a reference clock signal to coordinate data communications from the transmitter to the receiver. The clock lane may be assigned by determining signal margins of various lanes of the processor bus. The signal margins are determined by the transmitter sending a test pattern upon the various lanes and analyzing the received test pattern at the receiver. A dynamically assigned clock lane results increased overall signal integrity of communications between the transmitter and receiver. Further, a dynamically assigned clock lane may result in different lanes being assigned as the clock lane at distinct boot up instances, adding to the complexity of the unauthorized user determining the operational logic of the transmitter.

摘要： An optical electromagnetic radiation (EM) emitter and receiver are located upon a printed circuit board (PCB) glass security layer. A predetermined reference flux or interference pattern, respectively, is an expected flux or reflection pattern of EM emitted from the EM emitter, transmitted by the glass security layer, and received by the EM receiver. When the PCB is subject to an unauthorized access thereof the optical EM transmitted by glass security layer is altered. An optical monitoring device that monitors the flux or interference pattern of the optical EM received by the EM receiver detects a change in flux or interference pattern, in relation to the reference flux or reference interference pattern, respectively, and passes a tamper signal to one or more computer system devices to respond to the unauthorized access. For example, one or more cryptographic adapter card or computer system functions or secured crypto components may be disabled.

摘要： An interconnect device may include a first center conductor of a first material that has a first durometer. The first center conductor may be surrounded by a first inner dielectric ring, which may be surrounded by a conductive region of a second material having a second durometer. The second durometer may be different from the first durometer. The conductive region may have a first end that defines a first plane and a second end that defines a second plane. An outer dielectric ring may surround the conductive region. The first center conductor may have a first bulb and a second bulb, the first bulb may extend in a direction away from the second plane and beyond the first plane, and the second bulb may extend in a direction away from the first plane and beyond the second plane.
