Materials Selection

This guide explains FR4 vs Rogers vs Polyimide for PCB teams that need a realistic material decision. It covers where standard FR4 still works, when low-loss laminates deserve review, when polyimide belongs in the stackup discussion, and how to communicate material intent clearly to manufacturers.

This guide explains how to compare high frequency PCB materials without brand hype. It covers FR4 versus low-loss laminates, dielectric constant, loss tangent, stackup communication, quoting risks, and the design details that matter before fabrication.
