While I don't think you should be charged, I do remember working with Teradyne BGA connectors that had each row of balls 1/2 pitch offset from the previous row. At the time (2 years ago) the software on GSM's was not very capable of recognizing this connector (the connector body was white). It could be that your CM needs to upgrade the software (and/or cameras)...
The CM should have checked out this part previously and let you know about the possible issues...
just my opinion...

Sounds like they're charging you to resolve their P&P programs. THat would be like charging the customer who running their product when the machines went down.

I don't think we would charge for this. You paid for it up front, period.

Eric,
This is not an ECO. This board is a new board just introduced to our CM. We did pay a standard NRE charge to cover P&P programming, tooling, etc. Once the part was on the machine and running or getting ready to run, the CM started having trouble with the lighting of the camera. It took them 2 hours to get it right and now they are asking us to pay for the 2 hours of line time that was lost in order to set it up properly. My opinion is that this should be covered by the initial NRE charges. If it was a revision change or modification then I agree that the CM would charge some amount to cover the changes. This is not the case here.

Happy Halloween to all!!
It seems fair to charge a standard initial tooling price. But if I understand the original statement, this is a new part added to an existing board. Steve, after you have charged the tooling cost, how do you handle changes to the board? Essentially, every part of the process has to be changed or modified with the revision change. Isn't it fair in this case for the CM to charge the customer for these modifications?

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?
