JANUARY 2021 I DESIGN007 MAGAZINE 73 PCB fabricators. The stackup should be cre- ated at the schematic capture stage and flow through the project to CAM deliverables. This avoids expensive design changes at the end of the project. Stackup planning enables users to quickly explore alternatives in their substrate dimen- sions and material parameters to quickly assess the impact on performance. The right stackup strategy can reduce crosstalk and suppress EMI, ensuring that the signals will remain sta- ble in the intended environment. DESIGN007 References: 1.
