Beyond FR-4: High Performance Materials for Advanced Designs

Beyond FR-4: High Performance Materials for Advanced Designs

In "Tech Talk #4," we covered basic FR-4 and variants that have been used in the commercial and military market for the past few decades, but in this report we will delve into the newer materials that target a specific application and/or market segment. As printed circuit boards have become less a point-to-point wiring base and more an integral part of the signal path, so have the properties of the material become more important due to their effect on the signal.
