Assistant Engineer Production Interview Questions and Answers for Freshers

Perfect soldering on P.C.B requires proper temperature, clean surfaces, correct soldering technique, and quality solder.

• Maintain the soldering iron at the correct temperature for the type of solder being used

• Ensure the surfaces to be soldered are clean and free of any contaminants

• Use the correct soldering technique such as drag soldering or reflow soldering

• Use high-quality solder with the appropriate flux for better adhesion and conductivity

There are different types of fires such as Class A, B, C, D, and K. Prevention methods include proper storage of flammable materials, regular maintenance of equipment, and employee training.

• Class A fires involve ordinary combustibles like wood and paper

• Class B fires involve flammable liquids like gasoline and oil

• Class C fires involve energized electrical equipment

• Class D fires involve combustible metals like magnesium and titanium

• Class K fires involve cooking oils and greases...read more

Flux is a substance used in soldering to clean and protect the metal surfaces being joined.

• Flux helps remove oxidation and impurities from the metal surfaces to ensure a strong bond.

• It also helps prevent oxidation during the soldering process.

• Flux comes in different forms such as liquid, paste, or gel.

• Examples of flux include rosin flux, water-soluble flux, and no-clean flux.

Unit operation involves physical changes in material, while unit process involves chemical changes.

• Unit operation involves only physical changes in material, such as separation, filtration, etc.

• Unit process involves chemical changes in material, such as reactions, transformations, etc.

• Unit operations are usually reversible, while unit processes are often irreversible.

• Examples of unit operations include distillation, crystallization, etc.

• Examples of unit processes include oxid...read more

My engineering stream is focused on production engineering, which involves designing, implementing, and optimizing production processes.

• Specialized in designing efficient production processes

• Implementing automation and robotics to improve productivity

• Optimizing production lines for cost-effectiveness

• Utilizing lean manufacturing principles to reduce waste

• Collaborating with cross-functional teams to ensure smooth production operations

There are mainly three types of feeders: Vibratory feeders, Centrifugal feeders, and Reciprocating feeders.

• Vibratory feeders use vibrations to move materials along a conveyor belt.

• Centrifugal feeders use centrifugal force to move materials towards the outer edge of a rotating disc.

• Reciprocating feeders have a reciprocating motion to move materials in a linear direction.

STEL value stands for Short Term Exposure Limit, which is the maximum concentration of a substance that a worker can be exposed to in a short period of time.

• STEL value is typically expressed as a time-weighted average over a 15-minute period.

• It is used to protect workers from the adverse effects of short-term exposure to hazardous substances.

• Exceeding the STEL value can result in immediate health effects or exacerbate existing health conditions.

• For example, the STEL value for...read more
