Many of us design folks don't have all the fine pitch gear to lift a super-dense quad pack and solder on a new one. Same goes for some of my clients, mostly the start-ups. So, are there any service providers that can do these jobs on a prototype board or two? The usual fabs often don't like such small jobs although some would reluctantly do it for a good customer.
Sacramento would be great, or Bay Area if it has to be. There's always Fedex, so in a pinch even father locations could work.
