    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. …”
