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?

In short: almost every up-to-date fab is able to handle those 
structures. But you will have to pay them for.

Bad.

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.

This is not the only problem with your design. There are many 
unacceptable Errors even in this small Picture. I would refuse to 
produce such PCBs in any case.

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.

And then run a DRC (design rule check) with real world parameters from a 
manufacturer. When you go out of that DRC with no errors, then you are 
ready for manufacturing.
