Introduction to Microelectronics


Quiz Questions

1.MICROELECTRONICS is defined as that area of technology associated with and applied to the realization of electronic systems made of extremely small electronic parts or elements.
True
False

2. The earliest electronic circuits were fairly simple. They were composed of a few tubes, transformers, resistors, capacitors, and wiring. As more was learned by designers, they began to increase both the size and complexity of circuits.
True
False
3. Another major problem with vacuum-tube circuits was the method of wiring components referred to as POINT-TO-POINT WIRING. Does the Figure 1-2 show an excellent example of point-to-point wiring?
Yes
No
4. Figure 1-5 describes a
Hybrid integrated circuit
Film Integrated Circuits
Monolithic Integrated Circuits
5. Two types of monolithic fabrication discussed are the
Diffusion Method & Epitaxial Method
None
6. Figure 1-14 denotes a
Vacuum evaporation oven
Evaporation mask
7. A MICROCIRCUIT MODULE is an assembly of microcircuits or a combination of microcircuits and discrete components packaged as a replaceable unit.
True
False
8. _________ is a production method to prevent unwanted interaction between elements within a chip.
Isolation
Desolation

9. The methods of interconnecting circuitry in multilayer printed circuit boards are the
Clearance Hole
Plated through Hole
Layer Build up
All the three
10.

An INTEGRATED LOGISTICS SUPPORT PLAN (ILSP) determines the maintenance level for electronic assemblies, modules, and boards for each equipment assigned to an activity.

True
False
11.

Early electronic systems could be completely checked-out with general-purpose electronic test equipment (GPETE), such as multimeters, oscilloscopes, and signal generators. Using this equipment to individually test the microelectronics components in one of today’s very complex electronic systems would be extremely difficult if not impossible.

True
False
12. A CAT (Centralized Automatic Test System) is an on-line system that continuously monitors the performance of electronic systems, predicts system performance trends, and isolates faults to removable assemblies.
True
False
13. (GPETE) is an acronym for GENERAL-PURPOSE ELECTRONIC TEST EQUIPMENT.
True
False
14. The repair station power unit is a standardized system that provides controlled soldering and desoldering of all types of solder joint configurations. Is this what is shown in figure 2-1.
Yes
No
15. Hand tools in figure 2-10 represent

Pliers, tweezers and dental tools
Pulleys, tweezers and dental tools
16. ROSIN or RESIN FLUXES are the only fluxes to be used in electronic work.
True
False
17. Figure 3-8E represents a
Solder cup terminal
Hook terminal
Fork terminal
18. ELECTROSTATIC DISCHARGE (ESD) can damage or destroy many types of electronic components including integrated circuits and discrete components.

True
False
19. Three generally accepted methods of solder connection removal involve the use of Solder wick, a manually controlled vacuum plunger, or a motorized solder extractor using continuous vacuum and/ or pressure.

True
False
20. INTEGRATED CIRCUIT (IC)-Elements inseparably associated and formed on or within a single substrate.
True
