    Thermomechanical Performance of fr-4 Laminates in the Manufacturing Process of Printed Circuit Boards. por Rodríguez Vázquez, Carlos Alfonso

    Publicado 2016
    “…Typical problems are related with deformations of the PCB in the reflow process, such as “warpage”, which is a deformation along the “z” axis and is accompanied by other phenomena called “bow” and “twist’, “bow” is characterized by a curvature of cylindrical shape on both sides of the PCB whereas “twist” is characterized by the elevation of the corners. …”

    Molecular dynamics of coalescence and collisions of silver nanoparticles por Guevara Chapa, Enrique, Mejía Rosales, Sergio

    Publicado 2014
    “…When the original particles have their closest twins aligned to each other, the formed nanoparticle will likely stabilize its structure onto a particle with a defined center and a low surface-to-volume ratio, while nanoparticles with misaligned twins will promote the formation of highly defective particles with a high inner energy.…”
