Al Hosn Armored Systems Interview Questions and Answers

Answering questions related to JFET, SCR, impurity in semiconductor, gates, IC fabrication, resistivity of silicon, and transistors.

• JFET terminals are Gate, Drain, and Source.

• SCR terminals are Anode, Cathode, and Gate.

• Increasing impurity in intrinsic semiconductor decreases breakdown voltage.

• MOSFET gate is used as an inverter.

• Diffusion of resistors is difficult to fabricate in IC.

• Resistivity of pure Silicon is around 2300 ohm-cm.

• A transistor is made of two diodes.

Press tools are used in manufacturing to shape and cut materials. There are various types of press tools.

• Blanking tool

• Piercing tool

• Bending tool

• Drawing tool

• Forming tool

• Coining tool

• Embossing tool

• Extrusion tool

Cutting clearance for fine tool is crucial for precision and accuracy.

• Cutting clearance should be minimal for fine tools to prevent deflection and ensure accuracy.

• The clearance should be determined based on the material being cut and the tool being used.

• For example, a carbide end mill may require a smaller clearance than a high-speed steel tool.

• The cutting speed and feed rate should also be considered when determining the clearance.

• Regular maintenance and inspection of the to...read more

To calculate press force, multiply the area of the part being pressed by the pressure applied.

• Determine the area of the part being pressed

• Determine the pressure being applied

• Multiply the area by the pressure to get the press force

• Press Force = Area x Pressure

The basic tool structure consists of a handle, shank, and working end.

• The handle is the part held by the user and provides grip and control.

• The shank connects the handle to the working end and may be straight or angled.

• The working end is the part that performs the intended task, such as cutting or drilling.

• Examples include a hammer with a wooden handle, a screwdriver with a metal shank, and a saw with a toothed working end.

Communication is the exchange of information between individuals or groups through verbal, non-verbal, or written means.

• Communication involves the sharing of thoughts, ideas, and emotions.

• It can be verbal (speaking), non-verbal (body language), or written (emails, letters).

• Effective communication requires active listening and clear expression of thoughts.

• Examples include conversations, presentations, emails, and text messages.
