Round 2 - Technical 

(4 Questions)

  • Q1. What do you know about PCB ?
  • Ans. 

    PCB stands for Printed Circuit Board, a board made of non-conductive material with conductive tracks for electronic components.

    • PCB is used to mechanically support and electrically connect electronic components using conductive pathways.

    • It is made of non-conductive material like fiberglass, with copper tracks to connect components.

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

  • Answered by AI
  • Q2. What is the active and passive components?
  • Ans. 

    Active components require a power source to operate, while passive components do not.

    • Active components require an external power source to function, such as transistors and integrated circuits.

    • Passive components do not require an external power source, such as resistors and capacitors.

    • Active components can control the flow of electricity, while passive components simply store or dissipate energy.

    • Examples of active comp...

  • Q3. What is the difference between resistance and capacitor?
  • Ans. 

    Resistance is the opposition to the flow of current in a circuit, while a capacitor stores and releases electrical energy.

    • Resistance limits the flow of current, while a capacitor stores and releases charge.

    • Resistance is measured in ohms, while capacitance is measured in farads.

    • Examples of resistors include carbon film resistors, while examples of capacitors include ceramic capacitors.

    • Resistance dissipates energy in the...

  • Answered by AI
  • Q4. What do you know about SMT ?
  • Ans. 

    SMT stands for Surface Mount Technology, a method of electronic component assembly where components are mounted directly onto the surface of a printed circuit board (PCB).

    • SMT components are smaller and lighter than through-hole components, allowing for higher component density on PCBs.

    • SMT components are typically mounted using solder paste and reflow soldering techniques.

    • SMT technology allows for automated assembly pro...

Round 1 - Technical 

(2 Questions)

  • Q1. What is a transformer
  • Ans. 

    A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

    • Transformers are used to increase or decrease the voltage of an alternating current (AC) signal.

    • They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.

    • The primary winding receives electrical energy from a power source, while t...

  • Q2. What is a current
  • Ans. 

    Current is the flow of electric charge through a conductor.

    • Current is measured in amperes (A).

    • It is caused by the movement of electrons or ions.

    • Current can be either direct current (DC) or alternating current (AC).

    • DC flows in one direction, while AC periodically changes direction.

    • Examples of current include the flow of electricity in a circuit or the movement of ions in an electrolyte solution.

  • Q1. How many year experience ?
  • Q2. How to use bentonite use before pulsing
  • Ans. 

    Bentonite is used as a drilling fluid to stabilize boreholes before pulsing.

    • Bentonite is mixed with water to form a slurry and pumped into the borehole.

    • The slurry fills the borehole and stabilizes the walls, preventing collapse.

    • After the bentonite has set, pulsing can be done without the risk of borehole collapse.

    • Pulsing is a technique used in geophysical exploration to measure the properties of the subsurface.
