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 Altiu...

Electroplating is a process of depositing a layer of metal onto a surface using an electric current.
Electroplating involves immersing the object to be plated (called the substrate) into a solution containing metal ions.
A direct current is then passed through the solution, causing the metal ions to be attracted to the substrate and form a metal coating.
Common applications of electroplating include improving the appearan...

I applied via Walk-in and was interviewed in Jul 2024. There was 1 interview round.
Current is the flow of electric charge in a circuit.
Current is measured in Amperes (A)
It is the rate of flow of electric charge
Current flows from positive to negative terminal in a circuit
Examples: Direct current (DC) and Alternating current (AC)
A multimeter typically measures several parameters including voltage, current, and resistance.
Voltage
Current
Resistance
Continuity
Diode testing
A CRO (Cathode Ray Oscilloscope) is used to display and analyze waveforms, while a function generator is used to generate different types of waveforms.
CRO is used for visualizing electrical signals in the time domain, while a function generator is used to create specific waveforms like sine, square, triangle, etc.
CRO provides a visual representation of the input signal's amplitude, frequency, and phase, while a functio...
Normal soldering temperature typically ranges from 300 to 400 degrees Celsius.
Normal soldering temperature ranges from 300 to 400 degrees Celsius
Different types of solder may have specific temperature requirements
Using a temperature-controlled soldering iron is recommended for precise soldering
Excessive heat can damage components and create poor solder joints
Schematic diagrams show the electrical connections and functions of a specific circuit, while block diagrams show the components of a system and their connections.
Schematic diagrams focus on the details of individual components and their connections within a circuit.
Block diagrams provide an overview of the system by showing the components and their interconnections.
Schematic diagrams are commonly used in electronics t...
