Mr. Dartin XinWhat can I do for you?

vvias are small holes, usually,we say vias are holes less than 0.3mm.
Blind via is the via from top or bottom layer to inner layers, they are not through,we can see the vias from PCB top or bottom side. Buried via is the vias in the inner layers,we can not see these vias from PCB top or bottom side. Stacked vias are laminated blind or buried vias, multiple vias inside a circuit board built together around the same center |
