Abstract: Provided is an apparatus comprising a conductive particle interconnect (CPI) and an electroactive polymer (EAP) structure. The CPI includes an elastomeric carrier and a plurality of conductive particles dispersed therein. The EAP structure is disposed around at least a portion of the CPI. The EAP structure is configured to move between a first position and a second position in response to an electrical field. The CPI is configured to exhibit a first electrical resistance when the EAP structure is in the first position and a second, different electrical resistance when the EAP structure is in the second position.

Abstract: In an example, a composite thermal interface object includes a first layer including a first thermal interface material that has first compliance characteristics. The first layer includes first graphite fibers, and the first graphite fibers are aligned in a direction that is substantially orthogonal to a surface of the first layer. The composite thermal interface object further includes a second layer including a second thermal interface material that has second compliance characteristics that are different from the first compliance characteristics.

Abstract: A method and structure are provided for implementing manufacture of a printed circuit board (PCB) with one of an infrared (IR) reflective mask or a novel solder mask to minimize coefficient of thermal expansion (CTE) mismatch between PCB laminate and plated through hole (PTH) copper. At least one of an IR-reflective mask and a solder mask composition for use in IR reflow processes is created such that radiant heat is reflected away from the major portion of the PCB yet permitted to impinge upon the PTHs. The copper within the PTH expands due to radiant heating while the bulk laminate expansion is significantly reduced due to the reflected IR radiation. Consequently, the CTE mismatch is minimized and tensile strain of the copper in the PTH is reduced, providing enhanced reliability.

Abstract: A multilayer printed circuit board (PCB) includes a laminate between a first core and a second core. The first core is located in a middle position of the multi-layer PCB and includes a resistive heating element directly upon a first core substrate. A portion of the resistive heating element protrudes from the multi-layer PCB perimeter. A laminator that fabricates the PCB includes a platen, a power supply, a processor, and memory that has program instructions embodied therewith which are readable by the processor to cause the laminator to position the platen against a surface of the multi-layer PCB and cure the laminate by heating the multi-layer PCB with the platen and cure the laminate by heating the multi-layer PCB with the resistive heating element.

Abstract: An impact resistant polyhexahydrotriazine polymer, processes of forming an impact resistant polyhexahydrotriazine polymer, and an article of manufacture comprising an impact resistant polyhexahydrotriazine polymer are disclosed. The impact resistant polyhexahydrotriazine polymer includes at least one hexahydrotriazine group and at least one chain comprising an allylic portion and a styrenic portion. Variations in the chain control properties of the impact resistant polymer. The process of forming the impact resistant polyhexahydrotriazine polymer includes reactions between formaldehyde and at least two classes of monomer that form hexahydrotriazine groups and impact resistant chains. Adjusting relative monomer concentrations controls properties of the impact resistant polyhexahydrotriazine polymer. The article of manufacture contains a material that has an impact resistant polymer. Impact resistance of the impact resistant polyhexahydrotriazine polymer is dependent upon variation in relative amounts of monomers used in its synthesis.
