Introduction to Dielectric Constants and Materials A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor, but only slightly shift from Read more…
What is Differential trace impedance? Differential trace impedance is a critical aspect of high-speed PCB design, especially in applications involving differential signaling. It refers to the impedance between two traces carrying differential signals, which are equal in magnitude but opposite in polarity. Maintaining a consistent differential impedance throughout the length Read more…
Understanding SMT stencil area ratio What is SMT Stencil Area Ratio? SMT (Surface Mount Technology) stencil area ratio is a crucial parameter in the SMT assembly process.
