Characterizing Dielectric Loss in Adhesiveless Polyimide Substrates
Adhesiveless polyimide substrates eliminate high-loss acrylic adhesives, dropping dielectric loss tangents to 0.002 at 10 GHz when paired with smooth rolled copper.
Resolving Intermittent High Speed Signal Integrity Escapes Surviving Static Advanced Boundary Scan Verification
Resolving intermittent high speed signal integrity escapes requires pairing static boundary scan with embedded IJTAG at speed stress testing to catch dynamic physical layer failures.
IPC Slash Sheet Laminate Selection Principles
IPC-4101 slash sheets establish mandatory baseline physical, thermal, and electrical limits that override generic trade names to enforce material reliability.
Mid Loss Laminate Selection Criteria for High Speed Circuits
Mid-loss laminates optimize high-speed signal reach between 5 and 28 Gbps by controlling dielectric loss without imposing low-loss fluoropolymer costs.
