Hi Greg!
They're charging YOU time to create a vision database to place a part on a board they're building for you? WOW!
I gotta say, in the 17-yrs. that I've been in contract manufacturing, that's the first time I've ever heard of that...
We do have a flat NRE charge for initial P & P programming and tooling, but that includes everything, i.e.; Stencils, vision programs for placement, color coded production aids, screen printer programs, reflow oven and wave solder recipes, rework recipes if we need them, ect., ect...
But to have itemized charges for each and every individual facet of the programming needed for manufacturing? Getting a little anal if you ask me...

technetters,
We recently introduced a 516 pin 1mm BGA on one of our latest boards. Our
EMS provider is trying to charge us 2 hours of line time (for a significant
amount of money) for time spent adjusting the lighting on their GSM cameras.
They claim that the non-uniform ball grid layout was causing recognition
errors at placement. It has been a while since I've worked directly with
P&P equipment, but 2 hours of time seems a ridiculous amount of time to
adjust the cameras. Any thoughts?
