PRABHU STEELS Interview Questions and Answers

UPH stands for Units Per Hour, Line of Balance is a scheduling technique, PPM stands for Parts Per Million in quality control.

• UPH (Units Per Hour) is a measure of productivity in manufacturing, indicating the number of units produced in an hour.

• Line of Balance is a scheduling technique used in project management to track progress and ensure resources are allocated efficiently.

• PPM (Parts Per Million) is a measure of quality control, indicating the number of defective parts per...read more

SMT mounting flow chart is a visual representation of the steps involved in surface mount technology component mounting process.

• SMT components are picked and placed on the PCB using automated equipment.

• Components are then soldered onto the PCB using reflow soldering or wave soldering techniques.

• Inspection and testing are done to ensure proper component placement and soldering.

• Final inspection and quality control checks are performed before the PCB is considered ready for use.

A capacitor is an electronic component that stores and releases electrical energy.

• Capacitors are used to filter out noise in electronic circuits.

• They can store energy and release it quickly when needed.

• Capacitors are commonly used in power supplies, audio equipment, and electronic devices.

• Examples include ceramic capacitors, electrolytic capacitors, and tantalum capacitors.

SMT process stands for Surface Mount Technology process, which involves mounting electronic components directly onto the surface of a printed circuit board (PCB).

• Involves placing electronic components onto the surface of a PCB

• Utilizes solder paste to attach components to the board

• Involves reflow soldering to melt the solder and create a permanent bond

• Can include inspection and testing steps to ensure quality

• Common in mass production of electronic devices

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.

• Transistors are fundamental building blocks of modern electronic devices.

• They can amplify signals, regulate currents, and act as switches.

• Common types of transistors include bipolar junction transistors (BJTs) and field-effect transistors (FETs).
