All,
I am wondering if we are is missing Happy's point... or maybe it's me. I
think that what Happy was saying was that because of the way you build a
board, you cannot use blind vias to go from just any layer to just any
other layer. You have to set up the blind vias for drilling layer pairs,
taking into consideration how you are going to stack the board at
manufacture. How are you going to drill from layer 1 to layer 5 unless
it's controlled depth drilling?

> Hi,
>
> Can anyone recommend PCB prototype manufacturer? We are based here in the

> for a board with the following characteristics:
>
> Board Material :FR4 0.5 oz copper
> Dimensions: 25.4x25.4 mm
> Thickness: 0.8 mm
> Layers: 6
> Finish: Immersion Gold
> Vias: PTH, Blind Vias - L1-L2, L1-L4, L1-L5, L3-L6
> Panel: 10 boards/panel. with TDR coupon
> Panel size: 145x82 mm
> Impedance control
> Required leadtime: 7 days or less (pref. 5 days inclusive of delivery)
>
>
> Although for our prototype, we only need one panel or so. If you can
> recommend any manufacturer, I would greatly appreciate it. We need to get
