Hi Jenny! I attempted to pull together a test plan to assess the reliability of polyball component technology for a couple of our avionics applications. Thanks to the wonderful assistance of Technet I found two sources of polyball components in the Far East but have finally dropped the project as I could not get a quote for test devices from either company. Hope you have better luck.

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.
