PCB Via Design Rules for Reliable Manufacturing
PCB vias are critical structures that connect copper layers in multilayer printed circuit boards. Proper via design directly affects PCB manufacturability, electrical reliability, and production yield. This article explains the most important PCB via design rules, including via hole sizes, aspect ratio limits, annular ring requirements, and spacing guidelines. It also compares common via types such as through-hole vias, blind vias, buried vias, and microvias. By understanding these design parameters and aligning them with real PCB fabrication capabilities, engineers can...
