We have a pcb design with track space less than 5/5mil. And i was told many fab can not make it,it will take long time to change it. Anyone have recommendation of fab who can produce it?

But you will have to pay them for.

@Arkus Bruce (Company: electronic lab) (arkusbruce001) >We have a pcb design with track space less than 5/5mil. Bad. >And i was told many fab can not make it,it will take long time to change >it. I doubt it, especially in the screenshot shown. I guess you are just too lazy. Most manufacturer make 6/6 mil desgins using their standard process. Smaller track/gap is (much) more expensive. So your time to fix the design saves Money and provides a good opportunity to improve your layout skills. Njoy

Just have look at the lower left corner, there is a window with a LOT of error messeages . . .
Hi Njoy thank you for your suggestion, sound good idea. i'll make some changes before manufacturing to save money.

I have a Min Track/Spacing 4 / 4mil project produced at PCBGOGO. But the price of this line spacing is very expensive. It is recommended to modify your PCB design file. This will save you a lot of project costs.

For people, who also try to design with dense routings, the file found under the link might be an interesting lecture. Conclusion for one part: do not push to the manufacturer's boarders without any need. https://resources.ema-eda.com/pcb-design-content-central/hitchhikers-guide-to-pcb-design
