I'm working on several projects where I have 6-8 layer HDI designs. I need to find a cheap and affordable PCBA manufacturer either locally in the US or in Aisa? Anyone can suggest a good and & verified option?

 

Do you have any suggestions?

 

For PCB bare board, in the US, I've had good luck with American Standard Circuits PCB Manufacturer USA - American Standard Circuits (asc-i.com)
For assembly, I'm in Canada, microart has provided good quality with low volume. PCB Design, Prototyping, Production & Assembly by Microart Services
