A light emitting diode is a two lead semiconductor light source. ____ are used as indicator lamps in many devices and are increasingly used for other lighting. Has two leads + and -. All ___ require some form of current limiting, add resistors.

|
_____ is a two terminal device("Di) ____allow electricity to flow in only one direction. Acts as a one way valve for electronics. The arrow of the circuit symbol shows the direction in which the current can flow.
|
DIODES
|
|
_____ are a keystone of modern electronics. They are the heart and brains of most circuits. They are the ubiquitous little black “chips” you find on just about every circuit board. Many footprints, machine precut.
|
IC
|
|
_____ store electric charge. A ____is considered a passive device bc it does not actively affect electrical currents , instead ____ store electrical energy between electrical conductors. The number printed on ____refers to the amount of current it can passively hold. Ex. water storage tank with a shut off valve if it gets too full.
|
CAPACITORS
|
|
An ______also called a coil or reactor, is a passive two-terminal electrical component which resists changes in electric current passing through it. It consists of a conductor such as a wire, usually wound into a coil. When current flows through it, energy is stored temporarily in a magnetic field in the coil.
|
INDUCTOR
|
|
Ball grid array is a type of surface mount technology (SMT) that is used for packaging integrated circuits. _____is made up of many overlapping layers that can contain one to a million multiplexers, logic gates, flip-flops or other circuits.
|
BGA
|
|
|
_____is a system for assembling small electronic components on printed circuit boards through automated assembly._____components have short pins or flat contacts that are held onto the preprinted circuit board by a thin layer of solder paste. The board and components are heated in an infrared oven, which eliminates the solder paste and melts the remaining solder. When the circuit board cools, the solder solidifies.

Surface Mount Technology
|
|
|
______ is the process which joins together metal items by melting and flowing a filler metal into the joint between them.
|
Soldering
|
|
|
_____is an electrical switch that allows a low power to control a higher one. A small current energizes the relay, which closes a gate, allowing a large current to flow through
|
Relay
|
|
|
A____ is an electrical component that reduces the electric current. The ____ ability to reduce the current is called resistance and is measured in units of ohms. Ex. Analogy of water flow through pipes, the resistor is a thin pipe that reduces the water flow.
|
RESISTOR
|
|
A____is a semiconductor device used to amplify and switch electronic signals and electrical power. Most likely has 3 leads
|
TRANSISTOR
|
|
A____is best known for providing the physical link between 2 components.
|
CONNECTOR
|
|
|
Ship board without component, basically means " yes company needs the board that part but we do not have parts".
