Does anybody have a practical experience with solder paste dispenser for small-scale production (prototypes, or 10-20 pcs. batches)? What ptich size is realistic? Let's say that the speed is not an issue, but the quality is. - Deni

We are considering buying a new stencil washer machine. We stencil print boards with NC solder paste and in the near future Lead free solder paste. I'd like to hear your experience with this equipments and what you recommend.

I would like to know, if the solder paste for SMT is unpacked (the syringe is opened) and is stocked at room temperature, then when I should trash it. After 12 hours/24 hours exposure? Or any other suggested time? Thanks.
