Do you allow your manufacturer to do some changes to your PCB design? If yes, do you think that the manufacture can make your design better?

Absolutely not, and if they were able to make it better, than your design isn't sufficient to begin with. Designers design, manufacturers manufacture.

We just subcontract assemble boards, but have our preferred PCB supplier. If an existing board manufacture is transferred to them they often recommend change/ improvements which we have to get authorised from our customers. Although the boards may work ( electrically ) I pftem confer with the designers too to ensure reliable manufacturing quality etc

The problem is they said what we designed is not qualifyed for production and they have files called "DFM" which is used for the real production to fit with the production line

yes I think that make sense but are there any good way to let both sides win?

*You* may be well versed, but not every designer is experienced or even familiar with DFM.

I don't care how sophisticated the circuitry is, if you can't build it it's a lousy design, and as an EMS we see many designs that shouldn't have passed the review stage (if there WAS a review).

Holes too small for the PTH leads, unplugged vias in pads, HASL specified for high density designs, and designs with NO drawings, no notes, etc..

That said, our favored fab shops rarely suggest changes to a design unless the board files included panelization and the method isn't appropriate for the layout, or if the design is incompatible with standard methods and processes.

personally, I do allow. usually, they will do some design for manufacturability change. this cannot be avoided. I have read an interesting article talking about this question, maybe you can check: http://www.starivergroup.com/News/info.aspx?itemid=1064
