Free-Space Technique for Measurement of PCB Laminate Materials
PCB performance strongly depends on laminate dielectric constant and dissipation factor related to complex dielectric constant. Among the methods for measuring complex permittivity are waveguide, cavity resonator, open resonant cavities, split-post dielectric resonator and free-space techniques. The latter offers a simple, yet data rich, nondestructive characterization method.

Qualification vs. First Article Inspection
Military and commercial product suppliers often overlook what is being asked by their customer when they are asked to qualify a part. What’s more, there’s a disconnect between what FAI is and whether it is a sufficient technique for design qualification.
