Originally published at: Top PCB Material OEMs and Laminate Families | Sierra Circuits
PCB material OEMs such as Isola, Rogers, and DuPont develop laminates optimized for specific electrical and mechanical requirements. These laminates are grouped into different substrate families (FR4, polyimide, PTFE) based on their resin system, dielectric performance, and intended application. Understanding the strengths of different OEMs and dielectric families helps you select the right substrate for your design. In this article, we list major PCB laminate manufacturers and their strengths. We also discuss different printed board material families and their properties. Highlights: High-speed digital laminates such as Megtron 6, Astra MT77, and Tachyon 100G are used for 56G/112G networking, AI, and…
