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

“…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. …”

Análisis geomecánico utilizando el método RMR, de un macizo rocoso ubicado en el km 40 de la carretera Linares – Iturbide. por Garza Pérez, Magdaleny

“…The RMR (ROCK MASS RATING) method proposed by Bieniawski in the 80's will be used as a parameter to classify the quality of the rock mass from a geological engineer point of view, so with complementary data to establish the parameters of the rocky mass for the purpose of slope stability, determining the degree of risk and generating necessary measures to deal with possible damages that could be generated. …”

Expectativas de los estudiantes de primer ingreso en la Maestria en Contaduría: Caso FACPYA (Expectations of first year students in the master of accounting: Case FACPYA) por Hernández Campos, Alfonso, Tamez Garza, Silverio, Leal Martínez, José Luis, Garza Coronado, Jessica Lizzet

“…The results indicate, among other things, that the two main areas of interest for future work to students are the Finance and Taxation, and that their interest is directed to work in the private sector in a corporate or large firm, practically leaving out the public sector. Experton points out that the learning process is easier to students through laboratory practical situations followed by lectures given by the professor, and videos of case studies. …”
