WebMay 23, 2024 · Low aspect ratio: Contrary to through-hole vias in typical PCBs, microvias have small aspect ratio. The aspect ratio of these vias is preferably 0.75:1. Larger aspect ratios of 1:1, or even as high as 2:1, can be fabricated, but they bring reliability concerns. Because of this, they typically only span between a single layer.

WebOct 21, 2024 · So in our design, we have control only over the width of the traces. For most manufacturers, the minimum trace width should be 6mil or 0.152mm. That limitation comes from their manufacturing (etching) processes and the target yield. But to have some tolerance, we generally use 10-12 mil or 0.254-0.3 mm traces. WebJan 20, 2024 · So in this case the maximum current carrying capacity is 3.071 Amps, resulting in a temperature rise of 45 degC. Adding a Via A via is an electrical connection that links 2 traces that do not lie on the same PCB layer. A through hole via is a hole that is drilled all the way through the board and Copper deposited on its inner face.
