To all I politely disagree,
I have been to no less than six IPC sponsored seminars
specifically gear to the future trends in the IC industry.
We now have a presentation that doesn't focus on manufacturing
anymore, but how to use manufacturing techniques for routing
advances. We are currently working on a 2000 plus I/O BGA at .8 mm
pitch. I'm sure there are other board shops working with
customers with even higher routing needs. I'm surprised someone
directly from IPC hasn't responded to this e-mail. This has been one
of the most popular issues that I've attended in the last two years.
Our seminars for routing techniques has become the best
attended seminar we sponsor. Even over the PCB manufacturing
guidelines.
Just a thought,
