How are buried vias made

Web18 de abr. de 2024 · I suggest you use wide metal over wide metal, and have a line of vias down the middle of the metals, so the vias are fed with current from both sides and on each layer. Summary: draw sketches of the current flows. A long thin metal overlap with lots of vias in a line will cause massive current crowding. Current crowding is NOT what you want. WebThe downside of stacked vias is that they come with a higher cost than standard through-hole vias or blind/buried vias. A microvia is merely a very small via. As you can imagine, microvias are very desirable to PCB designers — the smaller the diameter, the more routing space you have on the board and the lower the parasitic capacitance, which is essential …
