Every beep, blink, and buzz around you is powered by electronics — and behind it stands a skilled hand. If you've ever wondered how devices think, repair, and come back to life, the Electronics Mechanic Trade (2nd Year) Practical Book by NIMI is your next big step into the world of innovation

Why This Trade Matters

Electronics aren't just gadgets anymore — they're the backbone of modern life. From the smartphone in your pocket to the solar inverter powering your home, from IoT-enabled smart cities to medical devices saving lives — electronics run the world.

 That means trained Electronics Mechanics are in high demand. Whether it's repairing TVs, building IoT prototypes, or troubleshooting industrial systems, this trade opens doors to careers in manufacturing, telecom, consumer electronics, automation, and more.

What You'll Learn in 2nd Year Practical:

Electronic Cables & Connectors:

Learn to identify, crimp, terminate, and test cables used in audio, video, RF, and networking.

Every connection counts — mastering cables means fewer faults and faster repairs.

Computer Hardware, OS,MS Office & Networking :

Hands-on training in assembling PCs, installing operating systems, configuring networks, and troubleshooting hardware. 

IT support is everywhere — this module makes you job-ready from day one.

Basic SMD Soldering & Desoldering:

Work with Surface Mount Devices used in modern PCBs — solder, desolder, and repair with proper tools

  Today's electronics are compact and complex. SMD skills set you apart as a pro.

 PCB Rework :

Detect defects, repair damaged boards, and restore functionality to real-world circuits.

PCB repair is a high-value skill in mobile, laptop, and appliance servicing.

Protection Devices & Electrical Control Circuits:

Understand fuses, MCBs, ELCBs, relays, DC motors, and stepper motors — the building blocks of automation.

Control circuits are used in robotics, industrial machines, and smart systems.

Communication Electronics:

Modulate and demodulate signals using AM, FM, PWM techniques. Build and test transmitters and receivers.

Radio, wireless communication, and signal processing are core to telecom and broadcasting.

Microcontroller (8051):

Program and interface the 8051 microcontroller — blink LEDs, read sensors, control displays, and more. 

Microcontrollers power everything from washing machines to drones. This is where coding meets hardware.

Sensors, Transducers & Applications:

Work with RTDs, thermocouples, proximity sensors, and LVDTs. Build IoT-based projects like smart lights and door watchers. 

IoT is the future — and you'll be building it.

Fiber Optic Communication:

Set up fiber optic links, perform modulation experiments, and understand high-speed data transmission.

Fiber optics is the backbone of the internet and telecom infrastructure.

Digital Panel Meters:

Interface LED/LCD displays and build voltage/current meters using decoder/driver ICs. 

Display systems are everywhere — from dashboards to industrial panels.

SMPS, UPS & Inverters:

Troubleshoot switched-mode power supplies, uninterruptible power systems, and DC-DC converters. 

Power electronics are critical in energy management and backup systems.

Solar Power Systems:

Test photovoltaic cells, wire solar controllers, connect inverters, and charge batteries using renewable energy.

  Green energy is booming — solar techs are in demand nationwide.

Cell Phone Repair:

Disassemble smartphones, test components, replace faulty parts, and format devices. 

Mobile repair is a good way to earn money on your own with little investment.

LED Lights:

Dismantle LED circuits, identify connections in LED stacks, work with protection circuits and regulators, and create series-parallel LED matrices.

From homes to streets, LEDs shine — fix them and shine too.

LCD & LED TV:

Identify and operate different controls on modern TVs, understand components and sections, troubleshoot faults, replace modules, and work with remote controls and HDMI interfaces.

TV repair is in demand everywhere, making it a smart local business skill.
