The UPMSP Vocational Mobile Repairing course is a Uttar Pradesh Board (UPMSP) vocational trade subject that introduces students to the practical craft of servicing and repairing mobile handsets. It suits secondary and intermediate vocational students who want a trade skill they can use in a repair shop, service centre, or their own small business, and it also appeals to self-learners who want structured grounding before entering the trade. The UPMSP Vocational Mobile Repairing study guide has 10 sections and about 2,963 words.
01Basic Electronics and Electrical Fundamentals
Basic Electronics and Electrical Fundamentals checks whether you can reason with voltage, current, resistance and simple semiconductor behaviour, not just recall symbols. Expect Ohm's law, series and parallel circuits, resistor colour codes, continuity and diode tests, capacitors, and transistors used as switches.
332 words, about 2 min02Mobile Phone Hardware Components and Architecture
Mobile Phone Hardware Components and Architecture tests whether you can identify blocks inside a smartphone and trace signal and power paths. Expect the SoC, baseband, RF front end, PMIC, charging IC, display and touch, cameras, audio, storage, sensors, connectors and antennas.
308 words, about 2 min03Mobile Phone Assembly, Disassembly and Tools
Assembly, Disassembly and Tools tests safe opening and reassembly: correct tool for each fastener, heat control on adhesive, flex handling, screw mapping and post-repair testing. Use the right driver: Phillips, Torx, pentalobe or tri-point.
293 words, about 1 min04Fault Diagnosis and Troubleshooting
Fault Diagnosis and Troubleshooting tests a logical path from symptom to cause: interview, visual inspection, power/current measurement, split-half testing, substitution and verification. Record the complaint in the customer's words and the phone's history: drop, water, repair, update.
285 words, about 1 min05Soldering, Desoldering and PCB Rework
Soldering, Desoldering and PCB Rework tests hand soldering, hot-air work, wick/flux use and damage avoidance on small pads and connectors. Tin the iron tip, keep it clean, and use flux for every joint.
305 words, about 2 min06Software, Firmware and Flashing Procedures
Software, Firmware and Flashing Procedures tests safe recovery of software faults: boot modes, firmware matching, backup, flashing and post-flash verification. Know the layers: bootloader, kernel, Android/system, baseband/modem.
272 words, about 1 min07Mobile Networks and Signal Testing
Mobile Networks and Signal Testing tests cellular basics and practical signal faults: SIM, bands, antennas, RF path, signal metrics and data settings. GSM, WCDMA, LTE and 5G NR use different bands and technologies.
292 words, about 1 min08Battery, Charging and Power Management
Battery, Charging and Power Management tests Li-ion behaviour, charging circuits and safe power diagnosis. Li-ion nominal is about 3.7–3.8 V, full charge 4.2–4.35 V, cutoff around 3.0 V.
275 words, about 1 min09Workplace Safety, ESD and Environmental Practices
Workplace Safety, ESD and Environmental Practices tests protection of technician, device and environment: static control, electrical safety, fumes, tools and e-waste. Wear a grounded ESD wrist strap with a 1 MΩ resistor and work on a grounded mat.
285 words, about 1 min10Entrepreneurship, Customer Service and Shop Management
Entrepreneurship, Customer Service and Shop Management tests whether you can run a repair counter professionally: cost a job, price it, record it, explain it and handle the customer's data and expectations. Expect break-even, stock control, written estimates, warranty and complaint handling.
