    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. …”

    Bioestratigrafía y microfacies de la formación cuesta del cura (cretácico inferior) en la Cañada Guadalupe del municipio de Iturbide, Nuevo León, México. by Coronado Díaz, Miroslava

    Published 2018
    “…The scarcity of information available to the focal points of this research is based on more complex organisms such as ammonoids and other macroscopic organisms, which is why the lack of studies based on foraminifera has not allowed establish more concrete biostratigraphic sequences. …”
