Original Abstract

Reflow process is an important part of the microelectronics manufacturing. Still discussed the introduction of the WEEE Directive 2003/108/EC standards and RoHS Directive 2002/95/EC got the soldering into new areas. There is a space for new material compositions which do not contain lead, new procedure process, device setting, and began to make greater use of protective atmosphere. This article is focus on nitrogen protective atmosphere. Soldering was made on alumina substrate with conductive motive created by silver paste without surface finish. Solder paste SAC305, Sn100C, SnAgCuBiIn was used and paste SnPbAg as reference. A measurement of wetting and visual inspection according IPC-610 was used to evaluate the influence of nitrogen atmosphere. Comparison between alumina and FR-4 with NiAu surface finish is shown at the end of paper.
