摘要

Electrical circuits may act differently in Arizona than they do in Alaska-potentially affecting the performance of computers and other electronics. A new technique identifies and quantifies an important cause of this temperature sensitivity. Researchers at the National Institute of Standards and Technology (NIST) and DuPont Electronic Technologies (Research Triangle Park, N.C.) have demonstrated a nondestructive method for measuring how temperature affects the electrical properties of three common circuit board materials (ceramic, polymer and glass). The work, described at a recent conference,* provides manufacturers with an accurate technique for measuring high-frequency electrical properties of substrates without cutting up the material-enabling faster, less expensive and easier testing-as well as a tool for designing circuits and substrates with improved performance.
