HDI PCB fabrication

Good day Robert, I have done some of your courses and like to watch all your videos. THANK YOU!!! I would like to find out from you the latest PCB fabricator you would recommend to do HDI prototype and small batch qty manufacturing. I have just completed another 12-layer HDI board that include some 0.4mm pitch BGAs and have to use u-via in pad and 3mil/3mil traces, lots of LVDS, etc. I staggered the micro vias, like you do. I have just submitted RFQs to PCB manufacturers, including Sierra, NCAB and others in China and are awaiting their responses.

Hello Arrie, thank you. We still mostly manufacture our prototypes through Exception PCB: https://www.exceptionpcb.com/ They are not what they used to be (talking to them is not as easy as used to be), but they are still ok.
