    Publicado 2002
    “…Por otra parte, se ha podido comprobar, que no existe diferencia significativaen el conocimiento del daño a la salud por el consumo de alcohol y tabaco; por lo cualno se puede considerar como un factor protector el tener una propensión de educacióncircunscrita a la salud.AbstractThe consumption of alcohol and tobacco is a remarkable social problem, and it is thatthere is a modification in the use pattern and in the class of the consumers. Numerousstudies point out the adolescent stage as that of more risk in the beginning of theconsumption of alcohol and tobacco, oscillating the age and indicating that if it isbegun in this habit to an early age the risk it increases. …”

    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. …”
