Vocabulary 1.1
Vocab 1.1
1.capacitor-An electrical device used to store electrical charge.
2.Cold Solder Joint-A solder connection that exhibits poor wetting and is characterized by a grayish, porous appearance due to excessive impurities in the solder inadequate cleaning prior to soldering &/or the insufficient application of heat during the soldering process.
3.Digital Multimeter- Electronic test equipment that can perform multiple tasks. Typically one capable of measuring voltage, current, & resistance.
4.diode-A two terminal device that conducts in only one direction
5.Dual In-line Package-A very common IC package with two parallel rows of pins intended to be inserted into a socket of through holes drilled in a printed circuit board.
6.Engineering Notation- A floating point system in which numbers are expressed as products consisting of a number greater than one multiplied by an appropriate power of ten that is some multiple of three.
7.Fuse-A protective device in the current path that melts or breaks when current exceeds a predetermined maximum
8.LED (Light-Emitting Diode)-An electronic device that conducts current in one direction only & illuminates when it is conducting.
9.Plastic Leaded Chip Barrier(PLCC)- A square IC package with leads on all four sides designed for surface mounting on a circuit board.
10.Printed Circuit Board(PCB)-Insulating board containing conductive tracks for circuit connections.
11.Resistor-Component made of material that oppose flow of current & therefore has some value of resistance.
12.Resistor Color Code-Coding system of colored stripes on a resistor to indicate the resistors value & tolerance.
13.Scientific Notation-Numbers entered as a number from one to ten multiplied by a power of ten.
14.SI Notation-Abbreviation of System International, a system of practical units based on the meter, kilogram, second, ampere, kelvin, mole, & candela.
15.Seven-Sigment Display- An array of seven independently controlled light-emitting diodes(LED) or liquid crystal display(LCD) elements, shaped like a figure - 8, which can be used to display decimal digits and other characters by turning on the appropriate elements.
16.Small Outline IC- An IC package similar to a DIP, but smaller, which is designed for automatic placement and soldering on the surface of a circuit board.
17.Solder-Metallic alloy of tin and lead that is used to join two metallic surfaces.
18.Solder Bridge-The unwanted formation of a conductive path of solder between conductors.
19.Soldering-process of joining two metallic surfaces to make an electrical contact by melting solder(usually tin and lead) across them.
20.Soldering Iron-Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten.
21.Tinning-The process of applying a thin coat of solder to materials prior to being soldered; For example, application of a light coat of solder to the filaments of a conductor to hold the filaments in place prior to soldering the conductor.
22.Transistor-Term derived from "transfer resistor." Semiconductor that can be used as an amplifier or as an electronic switch.
