Junior PCB Engineer Interview Questions and Answers

PCB stands for Printed Circuit Board. It is used to mechanically support and electrically connect electronic components.

• PCBs are used in almost all electronic devices, from smartphones to computers to medical equipment.

• They are made up of layers of copper and insulating material, with a design that connects the components in a specific way.

• PCBs can be single-sided, double-sided, or multi-layered, depending on the complexity of the circuit.

• They are essential for the proper fun...read more

PCB design involves several steps from schematic capture to manufacturing.

• Schematic capture

• Component placement

• Routing

• Design rule check

• Gerber file generation

• Manufacturing

Cadence Design System is used to execute PCB projects.

• Create a new project in Cadence

• Design the schematic using OrCAD Capture

• Create the layout using Allegro PCB Editor

• Verify the design using PSpice simulation

• Generate Gerber files for manufacturing

• Export the design to a CAM file for fabrication

• Collaborate with team members using Cadence Team Design

• Use Cadence DesignTrue DFM to ensure manufacturability

Schematic is a diagrammatic representation of a circuit while layout is the physical representation of the same circuit.

• Schematic shows the logical connections between components while layout shows the physical placement of components on the board.

• Schematic is used for designing and testing the circuit while layout is used for manufacturing the circuit board.

• Schematic is usually drawn using software like Eagle or Altium while layout is done using PCB design software like KiCA...read more
