WebIn order to answer the question of currentcarrying capacity of a via, it is necessary to determine its DC resistance. One way to do this is to look at the plating in the hole as a sheet of copper that has been bent into a cylinder. Using this approach, a 12-mil outer diameter (0,33 mm) plated cylinder when unfolded into a flat sheet of copper ... 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. impact gcsWebTable 6-4 in IPC-2221 demonstrates the relationship between copper foil cross-sectional area, temperature rise and maximum current carrying capacity among external conductors and internal conductors. Moreover, a simplified formula has been summarized based on the tables above: I = KΔT0.44A0.75. In this formula, K is a correction factor. lists in redis
