Factors such as the thermal compatibility of the insulation layer, the influence of copper foil type on signal quality, and the mechanical support provided by the aluminum substrate are often far more critical than surface-level parameters. Drawing upon real-world case studies, this article shares how to prevent common failures through judicious material selection and process control, helping you achieve more reliable circuit board designs in harsh environments characterized by high temperatures, vibration, and shock.
