Technical Proficiency: A deep understanding of PCB design software (such as Altium Designer, KiCad, Eagle, or OrCAD) and proficiency in using it efficiently is crucial. This includes knowledge of schematic capture, PCB layout, routing techniques, and design rule checks (DRC).
Electrical Engineering Knowledge: Strong fundamentals in electrical engineering are necessary to comprehend circuit designs, signal integrity, power distribution, and impedance control. Knowledge of electronics components and their characteristics is also vital.
Experience with Design Tools: Experience with CAD tools specific to PCB design is invaluable. Familiarity with library creation, component footprints, design libraries, and simulation tools can streamline the design process.
