A Tale of Two Vias: Filled vs Plated in Ceramic, Sapphire, Quartz & Glass
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.

Photosensitive Polyimides in RF Microsystem Design
Photosensitive polyimides (PSPIs) are transforming RF microsystem design by enabling high-frequency performance, compact layouts, and simplified manufacturing. With their low dielectric constant, excellent thermal stability, and UV-patternable nature, PSPIs are ideal for RF filters, interconnects, and advanced packaging. As systems push into 6G and terahertz domains, PSPIs are proving to be an invisible yet indispensable design advantage.
