Normally, for handling fees, adding 20% is pretty much standard. >We're planning to move to a new design and >architecture for our productline. The board we're >designing is a typical embedded board.

I'd design these out if I were you- it limits the shops that can do the work. Small companies DON'T design in BGA.

I have in my bag one of the best layout guys I've every known. There are guys all along the Mexican border who can do a great assembly job. Mexican workers are real artisans. But these guys have been burned a few times, and will only deal with people with proven financial resources. They won't be a partner unless you are a relative of Ted Turner. >I was hoping that some of you may have gone through >this type of process.

What you need is called an investor, who will put his name and money on the line. This guy will have enough clout to "fix" things when they train starts to run off the track.
