      Technical Terms of Soldering

      Preface

      This publication, "Technical Terms of Soldering", primarily in addressing electronic engineers and technicians involved in the Surface Mount Technology (SMT). Its main objective is to offer a rough-and-ready overview of the various phenomena that occur during soldering as well as to highlight possible problem areas within the current and future technical development of soldering. My sincere thanks go to President Mr. Makoto Sawamura as well as to his employees of the R&D Department of the Nihon Almit Co. Ltd.

      SJM – Low Silver Lead Free Alloys

      Due to steep rise of metal costs, examination of low silver Pb free solder is on the rise. Low silver SAC alloys have not been adapted to SMT assembly so far. Our SJM Solder especially improves thermal fatigue.
