The PCB Via Design Guide offers practical, real-world insights into designing reliable and manufacturable vias. This eBook helps you make informed decisions on selecting and implementing the right via structure for your designs, including via-in-pad, stacked/staggered microvias, and thermal vias.

The handbook starts with the fundamentals, explaining when and where to use through-holes, blind, buried, and microvias. It then dives into the manufacturing processes covering drilling, plating, backdrilling, and via filling.

Drawing from actual production data, the PCB Via Design Guide highlights the most common DFM mistakes made by PCB designers and provides actionable tips on drill file setup, clearance guidelines, and layout rules. You’ll also learn how to calculate drill, pads, antipads, and annular ring sizes.

This eBook also explains how vias impact signal integrity, including impedance changes, reflections, and parasitic effects. Finally, it covers the essential testing and inspection methods, including sample fabrication notes to establish clear communication with your PCB manufacturer.
