solder paste shelf life | 3 November, 2005

Hi We currently use a small amount of Alloy : 43Sn 43Pb 14Bi Flux: RMA-51AC, Metal : 88.5%. We use it for reworking a product and only consume about 100g per year, we are in the middle or ordering in some more paste but the MOQ is 500g. Is it possible to lengthen the shelf life by sealing in a vacuumed bag and freezing at -55degrees C. or is there any other way shelf life can be improved? the supplier wasnt much help.

thanks

Unforunately, the only one who can give you that answer is the manufacturer. They are the only ones who know what is in their paste and how it reacts to different situations and conditions.
