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

    Publicado 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. …”

    Distribución espacial de los vectores de las enfermedades re emergentes (chagas, paludismo y dengue) en el estado de Jalisco, México. por Magallón Gastélum, Ezequiel

    Publicado 2018
    “…A multidisciplinary analytical cross-sectional study, with stratified probabilistic sampling, divided into two aspects: a) Study to estimate point prevalence of the diseases indicated in the open population as well as the spatial distribution of the vectors that transmit these diseases and b) Intentional study in patients Febrile to determine the frequency of these diseases in their active phase. …”
