Hi Werner, I received a couple of responses off the list and will be chasing them up. Thanks for the extra suggestions. It was your paper in Global SMT and Packaging that alerted me to the existence of these balls. Early days yet and I can't go in to details at this stage, but they might help in the assembly of our product. All depends on cost and availability.
