Abstract: A self-heating solder flux material includes a solder flux material and a multi-compartment microcapsule. The solder flux material includes a solvent carrier, and the multi-compartment microcapsule includes a first compartment, a second compartment, and an isolating structure. The first compartment contains a first reactant, and the second compartment contains a second reactant. The isolating structure separates the first compartment from the second compartment. The isolating structure is adapted to rupture in response to a stimulus.

Abstract: A triggering condition is applied to a conductive polymer positioned in a drilled hole in a printed circuit board. The applied triggering condition causes the polymer to vertically expand within the drilled hole such that the expanded polymer creates an electrically conductive path between contact pads located in different layers of the printed circuit board.

Abstract: An electromagnetic radiation (EMR) receiver is located upon a printed circuit board (PCB) glass security layer. EMR flux is transmitted by the glass security layer and received by the EMR receiver. When the PCB is subject to a tamper event the EMR transmitted by glass security layer is increased. A monitoring device that monitors the flux or interference pattern of the EMR received by the EMR receiver detects a change in flux or interference pattern and passes a tamper signal to one or more computer system devices to respond to the tamper event. For example, one or more cryptographic adapter card or computer system functions or secured crypto components may be disabled.

Abstract: A flame retardant lysine-based derivative, a process for forming a flame retardant lysine-based derivative, and an article of manufacture comprising a flame retardant lysine-based derivative are disclosed. The flame retardant lysine-derived molecule can be synthesized from a bio-based source, and can have at least one phosphoryl or phosphonyl moiety. A flame retardant proline-based derivative, a process for forming a flame retardant proline-based derivative, and an article of manufacture comprising a flame retardant proline-based derivative are also disclosed. The flame retardant proline-derived molecule can be synthesized from a bio-based source and can have at least one phosphoryl or phosphonyl moiety.

Abstract: In an example, a dry film solder mask (DFSM) composite laminate material is disclosed. The DFSM composite laminate material includes a printed circuit board (PCB) laminate material, a cyclic compound chemically bonded to the PCB laminate material, and a DFSM material. The DFSM material is reversibly bonded to the PCB laminate material via the cyclic compound.

Abstract: To provide for a physical security mechanism that forms a complete envelope of protection around the cryptographic module to detect and respond to an unauthorized attempt at physical access, a tamper sensing encapsulant generally encapsulates the cryptographic module. The tamper sensing encapsulant includes a first shape actuation layer associated with an electrically conductive first trace element and a second shape actuation layer associated with an electrically conductive second trace element. The first shape actuation layer is positioned against the second shape actuation layer such that the first trace element and the second trace element do not physically touch at an operating temperature of the cryptographic module and do physically touch when the first shape actuation layer and the second shape actuation layer are thermally loaded. Upon first trace element and the second trace element touching, a circuit is formed that disables the cryptographic module.

Abstract: A self-heating thermal interface material (TIM) may be formed using heating components dispersed within the TIM. The heating components may produce heat when the TIM is compressed. The heating components may be formed from microcapsules and the microcapsules may contain exothermic reactants. The reactants may be isolated from contact within the microcapsule until a compressive force is applied.

Abstract: A repatternable nanoimprint lithography stamp includes a magnetic substrate and magnetic core nanoparticles. The magnetic substrate includes a magnet and a magnetic mask, and the magnetic core nanoparticles are arranged in a pattern on a surface of the magnetic substrate. The pattern is defined by selective application of a magnetic field to the magnetic substrate using the magnet and the magnetic mask.
