Filled vias are solid metal connections through advanced substrates like ceramic or glass—ideal for high-power, high-frequency, or mission-critical designs. Plated vias, with metal-lined walls, are simpler and cheaper but offer less conductivity and thermal performance. Choosing between them isn’t just technical—it’s strategic. Like a strong foundation, filled vias offer depth and reliability when your design truly demands it.
