OBJECTIVES:

After going through this module, you are expected to:

Conduct complete testing of termination/connection of electrical wiring/electronics circuits in compliance with specifications and regulations using appropriate procedures and equipment

ELECTRONIC HAND TOOLS AND EQUIPMENT

ELECTRONIC HAND TOOLS AND EQUIPMENT

To work with electronic and electrical circuits, a beginner needs to acquire special hand tools and equipment. Each of these hand tool and equipment does one or more specific job in connecting, replacing, securing and troubleshooting of electronic circuits.

Basic Electronic Hand Tools and Equipment

Soldering Iron/Pencil

used to join two or more metal conductors with the support of soldering lead melted around it.

Basic Electronic Hand Tools and Equipment

Desoldering Iron/Pencil

used to unsoldered unwanted parts or component in the circuit with the support of soldering pencil

Basic Electronic Hand Tools and Equipment

Flat-head Screwdriver

used to drive a slotted screw head

Basic Electronic Hand Tools and Equipment

Philips-head screwdriver

Also called the crosshead screwdriver; used to loosen or tighten crosshead

Screws

Basic Electronic Hand Tools and Equipment

Side Cutter Pliers

is used for cutting or trimming of connecting wires or terminal leads in the circuit board

Basic Electronic Hand Tools and Equipment

Long-nose Pliers

used for holding, bending and stretching the lead of electronics component or connecting wire

Basic Electronic Equipment

Multimeter/Multitester

are tools used to measure current, voltage and resistance. The primary difference between the two is the display, an analog multimeter (Fig. A) uses a needle to show the value, while a digital multimeter (Fig. B) will show the results as numbers on a screen.

Basic Electronic Equipment

Portable Electric Handrill

is used for boring hole/s in the plastics chassis or metal chassis

Basic Electronic Equipment

Multi-Volts Power Supply

is used to supply the desired direct current voltages in the circuit

Occupational Health and Safety

with the use of electronic tools and equipment:

• Keep all tools in good condition with regular maintenance.
• Use the right tool for the job.
• Examine each tool for damage before use and do not use damaged tools.
• Operate tools according to the manufacturers’ instructions.
• Provide and properly use the right personal protective equipment.
