Printed Circuit Board stackup refers to the arrangement of conductive copper layers and insulating dielectric materials in a multi-layer printed circuit board. Think of it as the blueprint that dictates how signals, power, and ground are distributed across the board. A proper stackup design ensures signal integrity, minimizes electromagnetic interference (EMI), and supports efficient ... https://www.pcbhamal.com/what-is-printed-circuit-board-stackup-design/
