Multi-Layer PCB

1.Up to 64 layers;
2.Back drilling can reduce the loss on signal transmission;
3.Aperture ratio 15:1, plate thickness 0.4-10.0mm;
4.Blind buried hole technology, impedance control;
5.With Kingbrother’s technology inter-layer alignment deviation can be control within35um;
6.Adopt the special design methods- air vent design to improve the binding force between copper layer and hole wall.
7.Besides, our inner layer connection quality control method can improve the process parameters and special parameters, so that improve inner layer connection quality.
