Study Notes

Pliers

Pliers are useful for pulling, twisting, bending and shaping wires
They can be used to position small components
Pliers can cut wire and provide excellent grab control and long reach for fine work
Long nose pliers are useful for reaching into confined spaces
Needle nose pliers have a narrow jaw designed for intricate work

Tweezers

Tweezers provide more gripping precision than pliers
They are ideal for positioning surface mount components

Diagonal Cutters

Designed to cut copper wire
Easily cuts "soft" metals like copper, brass, aluminum, and iron
The beveled edge leaves a sharp spike on the wire because the jaws force the wire to break apart
Useful for cutting wires and component leads

Flush Cut Cutters & Shear Cutters

Designed to leave a smoother surface after cuts
The reduced beveled edge requires less force to cut through wire than diagonal cutters
Blades are very fragile compared to a diagonal cutter

Wire Strippers

Strip the outer insulation off of wire without cutting the wire
Adjustable or fixed, manual or automatic

Screwdrivers

Used for driving screws or bolts with special slots
Rotate other machine elements
Consists of a head or tip (turns screw), a shaft, and a handle (applies torque to rotate the tip)
Can be manual or powered

Soldering Iron

Supplies heat to melt solder
Solder will flow into the joint between two work pieces
Low power irons: 15 to 40 Watts – range $15 to $80
Temperature-controlled irons: 0 oC to 350 oC – $160 ↑ ↑

Types of Desoldering Tools

Used to remove solder from a printed circuit board
Required to remove components from a circuit for troubleshooting, repairing, replacement, or salvage.

Desoldering Tools

De-soldering pump: Prime the pump, release to vacuum up liquid solder. Only $5 to $12, but requires cleaning.
Solder wick: Finely braided 18 to 42 AWG copper wire coated with rosin flux, “absorb” solder. Rolls start at $5.
De-soldering station: Hot air pump, also called a rework station. Expensive, $150 to more than $1000.

All-in-One Workstations

Combination of soldering and desoldering tools

PCB Stand & Bench-top Vise

Helping “Third Hand” holds the PCB securely in place
Useful during soldering and inspections

Solderless Breadboards

Construction base for reusable prototyping of electronics
A perforated plastic cover hides a special pattern of metallic strips underneath.
Component leads and wires are inserted into specific holes to create simple circuits.

Breadboard Limitations

Current and voltage limitations
- Board overheats & melts with high current/voltage
- Arcing may occur between nearby connector rows
Frequency limitations
- High frequencies (>1 MHz range): noisy responses
- Wires can start to look like inductors and capacitors
- Very low frequencies: contact resistance is a problem
Metal contacts wear out with repeated use
Circuit complexity limitations
- Overflowing connectors can easily be disturbed
- Troubleshooting becomes difficult to manage
- Contact resistance develops over time
