...Wei Liu; Yanhong Tian; Lei Yang; Chunqing Wang; Lining Sun Purpose The purpose of this paper is to investigate oxidation and the Au‐Sn reaction of laser reflowed (LR) micro‐solder joints when different protective atmospheres were applied. Design/methodology/approach A N2 atmosphere at room...

...G. Takyi; N.N. Ekere Purpose The purpose of this paper is to evaluate the effect of nitrogen and air atmospheres on the solderability testing of plasma‐treated hot air solder level (HASL) finish printed circuit boards (PCBs). Design/methodology/approach In this paper, the soldering performance...

... gas flow required. This allows enhanced stability of the control system and ensures that inert gas flow is not incessantly reacting to control the oxygen level to the set point. © MCB UP Limited 1997 Soldering Ovens Flow Atmosphere The use of inert gases to create an oxygen...

...F.J. de Klein Reflow soldering in a controlled O₂ atmosphere will lead to practical benefits in the wetting behaviour of solder pastes. The required O₂ level and its control depend on the solder paste used and the solderability of the materials to be joined. For a typical...
