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

Dear Luciano

How are you?

Yes.we are a PCB facotry. Some times. our customer send us the PCB gerber files. we will help to check the gerber files at first. when we saw the pcb gerber files. we will find some questions. like: a 2 layer pcb boards. there are two lines need 50 OHM impedance. but there are no any copper around the line. we need the copper to obstruct the signal. So. we suggest to change the 2 layer pcb to 4 layer pcb. we need to add L2 layer and L3 layer. L2 and L3 layer are copper layer. However. When we need to change the design. we must check with our customer. and after our customer approve the change. than .we start to produce the PCB. If our customer did not approve. we can not change any things.

Dear Luciano. we produce PCB from 1layer to 90 layers.If you need PCB boards. we can offer some free PCB samples to you at frist. to check the quality. and we can produce quick turn pcb. lead time is short. our web: http://www.alcantapcb.com

Thank you.

Henry.

Sometime yes, if your design is not good enough, then supplier provide a good solution or suggestion, then you can try. Supplier is not only a supplier, sometime they're professional and expert on their area. But change should follow your change management system.

We can provide better suggestions to customers, but customers do not agree, we will make products according to the original design of the customer, otherwise it will cause disputes. There is also a case,we are not sure whether the customer design has specific needs and we are not allowed to change it, so the supplier opinions must be mentioned, also to make the perfect product, but the most general decision right is the customer .

Very broad topic. Designers own design. Manufacturing engineers can suggest design changes based on DFM, DFX DFA analysis. These are suggested, so the board is manufacturable with very low to no rework. Both design and manufacturing have their expertise in their own field. Both should work together towards creating the better product.

Yes, of course, considering your manufacturer knows how to design and has a very good design team. Additionally, your manufacturer must have years of expertise to design complex circuit boards. Few manufacturers offer design to assembly services. All you need to do is keep a close eye on your manufacturer.
