Electrochemical Noise Analysis of Nickel Based Superalloys in Acid Solutions por Gaona Tiburcio, Citlalli, Aguilar M, M.R, Zambrano Robledo, Patricia del Carmen, Estupiñan López, Francisco Humberto, Cabral Miramontes, José Ángel, Nieves Mendoza, Demetrio, Castillo González, E., Almeraya Calderón, Facundo

“…In this paper we study the corrosion behavior of nickel-based superalloys (Inconel 690, Inconel 718, Incoloy 800, Incoloy 825), compared with commercial steels (carbon Steel 1018 and stainless steel 304), in acid (10% H2SO4 and 10 % CH3COOH) and H2O at room temperature, by electrochemical noise technique, with sampling 1024 points per second. Statistical analysis of electrochemical noise technique yielded LI localization index, the type of corrosion and the noise resistance as well as the corrosion rate. …”

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. …”
