16 Layer HDI prototype:
- PCB Layer: 16Layer
- Material: FR4 High TG
- Board thickness: 5.08mm,
- Finishing copper thickness: inner and outer 2/2oz,
- Surface finished: ENEPIG.
- Blind and Buried vias with 0.2mm in L1-L2,L2-L3,L14-L15,L15-L16, impedance control 50 ohm +/-10%.
- Contersink holes
- Impedance control
The board used a special surface finishing ENEPIG, it’s fantastic for ping board.
