Dual In-Line Package (DIP)
A IC package with two parallel rows of pins intended to be inserted into a socket of through holes drilled in a printed circuit board.
Fuse
A protective device in the current path that melts or breaks when current exceeds a predetermined maximum value.
Cold Solder Joint
A solder connection that exhibits poor wetting and is characterized by a grayish appearance
Plastic Leaded Chip Carrier (PLCC)
A square IC package with leads on all four sides designed for surface mounting on a circuit board.
Engineering Notation
A 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.
Diode
A two terminal device that conducts in only one direction.
SI Notation
Abbreviation of System International, a system of practical units based on the meter, kilogram, second, ampere, Kelvin, mole, and candela.
Small Outline IC (SOIC)
An IC package similar to a DIP, but smaller, which is designed for automatic placement and soldering on the surface of a circuit board.
Seven-Segment 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.
Capacitor
An electrical device used to store electrical charge.
Resistor Color Code
Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance.
Resistor
Component made of material that opposes flow of current and therefore has some value of resistance.
What is 60/40 solder?
Consists of 60% tin and 40% lead. Has a low melting point
Digital Multimeter
Electronic test equipment that can perform multiple tasks. Typically one capable of measuring voltage, current, and resistance.
Printed Circuit Board
Insulating board containing conductive tracks for circuit connections.
LED
Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting.
Solder
Metallic alloy of tin and lead that is used to join two metal surfaces.
Scientific Notation
Numbers entered as a number from one to ten multiplied by a power of ten.
Soldering
Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and lead) across them.
Transistor
Semiconductor device that can be used as an amplifier or as an electronic switch.
Tinning
The process of applying a thin coat of solder to materials prior to their being soldered
Solder Bridge
The unwanted formation of a conductive path of solder between conductors.
Soldering Iron
Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten.
