Industrial Electronics Study Guide for Units 1 & 2

Screw Driver Tool Function

Used to tighten & loosen threaded screws that secure circuit boards, industrial panels, and equipment enclosures

Screw Driver Proper Use

Select exact match to not strip screw heads

Screw Driver Puncture Hazard

Never hold work pieces in palm while driving screws

Needle Nose Pliers Function

Designed to reach into small areas

Needle Nose Pliers Proper Use

Grip firmly on rubber insulated for stability; Do not use on energized live circuits

Wire Strippers Function

Removes outer plastic insulation from copper conductor wire.

Wire Strippers Proper Use

Match wire size gauge & squeeze handles; if size it too small it can cut the copper strands

Wire Cutters Function

Used to cut wire

Wire Cutters Proper Use

Wear safety glasses, shield wire, keep fingers clear of blade; don’t use on steel wire & hardened bolts (ruins blades)

Digital Multimeter (DMM) Function

Diagnostic tool (measures Voltage, Current, Resistance, etc.)

Digital Multimeter Proper Use

Set rotary dial to correct measurement; turn off when done; don’t use on live power circuit

Heat Gun & Heat Shrink Function

To shrink protective tubing over exposed wire joints & insulate splices

Heat Gun & Heat Shrink Proper Use

Keep nozzle moving/never touch metal; Place standing up

Soldering Iron Function

Melt component leads & wire terminal to connect (strong joints)

Soldering Iron Proper Use

Return to safety stand, not hot on desk, use fume hoods & wash hands after

Breadboard Description

Temporary construction base electronics connects components without soldering required

Breadboard (why use)

rapid prototyping & lets you troubleshoot mistakes instantly

Rows

Only holes in the exact same 5-hole row are connected

Center Gap

Zero power can cross the center gap

Types of Power Rails

Red - positive rail; Blue - ground rail

Breadboard (Vocabulary)

A reusable, solderless platform used for building and testing temporary electronic circuits.

Prototyping (Vocabulary)

The process of building a quick, physical model of a design to test ideas before final manufacturing.

Powerrail

Long vertical strips on edges of breadboard used to deliver power (+) and ground (-)

Terminal Strip (row)

Connected 5-hole horizontal rows to plug in components & form circuit connections
