Happy Holden: ECWC15 Virtual Event a Success This is the first ECWC (Electronic Circuits World Convention) that I have not attended in person since 1978. To refresh your memory, these are held every three years on a rotating basis. I always look forward to these events, not just because they include some of the best presentations you will hear, but also because they bring all my old friends together one more time. For the last three, however, I have been just one of only a dozen or so Americans to attend. This illustrates how much the electronics manufacturing arena has changed.
