"We were bringing up a new product line and needed a functional test system fast. The team at Cyth helped plan the project, fully developed the fixturing and DUT connectivity, and provided a software framework we could easily update with new tests. We simply didn't have the bandwidth to take on all this work ourselves while supporting existing lines."
