The main goal of this paper is to highlight the importance of interrelating the physics and the chemistry in wave soldering and soft soldering in general. Often we find the disciplines of chemistry and physics being analyzed distinct and separate. However in the quest for alternative ways for leading edge competitive and especially environmental friendly manufacturing, separating or ignoring this interrelationship is detrimental to the success of No-Residue soldering....

It appears very logical that the successor of the 0402 size SMD would be the 0201. Curves showing the life-cycle of a body size, from introduction to most used to only for special cases, are very similar for the 1206, 0805, 0603 and 0402. So there is reason to expect that the same will happen with the 0201. Until now there is only little evidence for this, but most technologies come later than expected but faster than expected!...

The popular tin (Sn) rich lead free solders are causing severe corrosion to many of the materials used in today's Wave Solder systems. Users are experiencing higher maintenance frequency and reduced life of wave solder machine components. This paper describes the effects of Sn rich solders in contact with various materials and discusses alternate methods to alleviate this problem....

The electronics business has been a rather heated, if not over-heated, environment for many years. This has lead to a forgiving climate regarding inefficiencies, as resources have not been stretched and getting products out has been top priority. It might now be time to invest in some reflection on the strategies and tactics applied to the production environment in order to be prepared for the ‘heat’ of the future. Focusing investment in the right resources, and not sub-optimising, is the way to go....

Odd or SMD? At one time it was clear. An SMD component was placed on the surface of a PCB and all others were defined as 'odds' or 'specials'. This article discribes the changes and how equipment manufactorers react on it....
