    Resiliencia en el uso de las aplicaciones didácticas interactivas en Estudiantes Universitarios después de la pandemia. Estudio Comparativo by Pérez-Martínez, Katia Site, Saldaña-Pérez, Juan Enrique, Mendoza-Vargas, Marta Magdalena

    Published 2024
    “…A ambos grupos se les aplico la encuesta llamada: “Escala de Aplicaciones Didácticas Interactivas”, la cual está integrada por 10 ítems de tipo Likert. La primera muestra fue tomada en el año 2018, y la segunda en el año 2023, esto permitió contrastar la diferencia entre sus respuestas, ya que en la primera, la aplicación de Power Point resulto ser la de mayor conocimiento y uso por los estudiantes, sin embargo, después de la pandemia, los estudiantes mostraron una mayor variabilidad ante el uso de las diversas aplicaciones didácticas interactivas, aunque si bien, refieren usar ahora más de una, Power Point sigue siendo la de mayor conocimiento.  …”

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

    Published 2016
    “…In 2006 the Restriction of Hazardous Substances (RoHS) prohibited the use of lead (Pb) in solder paste, which has a melting temperature around 180oC, whereas lead-free solder pastes have a melting point around 230oC, 30oC-40oC higher than Pb solder paste, this has generated PCB thermo mechanical problems due to the temperature increase at which the material is exposed. …”
