UPMSP High School Mobile-Phone Repair - Code 980 study plan

UPMSP High School Mobile-Phone Repair - Code 980 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Safety, Tools and Workshop Practice & Basic Electronics and Electrical Fundamentals

Set up a safe bench: identify and lay out ESD mat, wrist strap, fume extractor, fire-safe power strip and insulated tools, then demonstrate correct grounding before touching a board.
Distinguish series and parallel circuits by measuring voltage and current in two hand-built resistor circuits and stating the expected value before measuring.
Apply Ohm's law and power formula to calculate the correct series resistor for an LED across a 5 V rail and verify the result on the bench.
Demonstrate safe handling of lithium-ion cells and a DC power supply: set current limit, explain short-circuit risk and describe first response to a swollen battery.

A one-page bench safety checklist plus a signed lab log with measured-versus-calculated values for three circuits.

Week 2

Read a schematic of a phone power section and trace the path from battery connector through charger IC, PMIC and buck converters to the main rail.
Use a multimeter in continuity, diode and DC-voltage modes to identify a shorted capacitor and an open resistor on a scrap board.
Describe the role of CPU/SoC, RAM, eMMC/UFS storage, PMIC, charging IC, RF transceiver, PA, antenna switch and sensors, and locate each on a real scrap board.
Measure a crystal oscillator and explain in writing why clock failure stops boot.

Annotated photographs or hand sketches of one scrap board labelling at least 12 key components with their function.

Week 3

Identify SMD package types (0201, 0402, 0603, QFN, BGA, connectors) by measurement and state the rework risk of each.
Practise drag-soldering and hot-air reflow on scrap boards until you can remove and refit a 0402 resistor and a QFN IC without lifting pads.
Explain and demonstrate ESD-safe desoldering with wick and a heated tip, then clean flux residue and inspect under magnification.
Describe BGA reballing steps in sequence and state at least three failure modes of a poorly reflowed joint.

Five practice boards with removed and refitted components, plus a photo log of before/after joints rated pass or fail.

Week 4

Apply a structured diagnostic sequence (visual, current draw, voltage rails, then signal) to three dead-phone scenarios and record every measurement.
Diagnose no-charge and no-power faults by isolating battery, charging port, charging IC and PMIC using current-draw readings from a bench supply.
Distinguish hardware from software boot failure using current draw, recovery-mode response and display behaviour, and justify each conclusion in writing.
Explain water-damage assessment and cleaning procedure, including when a board is beyond economical repair.

Three completed diagnostic worksheets, each ending in a stated root cause or a ranked list of suspects with the next test named.

Week 5

Explain the boot chain (bootloader, recovery, kernel, system) and identify which partition or stage each common symptom points to.
Perform a factory reset, cache wipe and firmware flash on a practice device using the correct tool for that chipset, and verify IMEI and baseband survive.
Describe SIM card electrical interface, PIN/PUK handling, and the difference between SIM, eSIM and network lock states.
Explain IMEI structure, why IMEI alteration is illegal in India, and how to verify a device's IMEI status legitimately.
Distinguish 2G, 3G, 4G and 5G band and technology basics well enough to explain a no-service complaint caused by band or carrier mismatch.

A written flashing log for one device recording tool used, firmware version, outcome and post-flash checks, plus a one-page IMEI legality note.

Week 6

Build a symptom-to-test decision tree covering no power, no display, no charge, no network, no audio and overheating, with at least two tests per branch.
Write a customer-facing fault report template that states the observed fault, the tests done, the recommended repair and the risk of data loss.
Draft a transparent pricing and warranty policy covering parts, labour, turnaround and what voids the warranty.
Role-play a dispute over a repeat fault and record how you explain the diagnosis without blaming the customer.

A printed decision-tree poster for the bench plus a customer intake form and warranty policy used in one role-play.

Week 7

Prepare a simple shop budget listing tools, rent, parts stock, power and staff, and calculate the break-even repairs per month.
Explain GST registration thresholds, invoice requirements and record-keeping duties for a small repair shop in Uttar Pradesh at a general level, flagging where an accountant must be consulted.
Describe lawful handling of customer data during repair, including backup consent and device-wipe policy.
Re-run two earlier failed diagnostic worksheets and correct the reasoning errors you find.

A one-page shop business plan with break-even figure, price list and data-handling policy.

Week 8

Complete a full practical project end to end: intake, diagnosis, repair, rework, testing and handover, within a stated time limit.
Demonstrate safe bench shutdown and tool maintenance, including tip care, wick storage and battery disposal.
Answer viva questions aloud on safety rules, soldering parameters, boot chain and IMEI law, recording yourself and reviewing for gaps.
Sit one timed mixed mock test across all nine domains and review every wrong answer to a stated correct principle.

A completed repair project file with photos, measurements and a signed handover note, plus a scored mock test with a written error review.

Week 2: You can trace a phone power path on a schematic and correctly find a short with a multimeter without help.

Week 4: You have diagnosed three dead-phone scenarios and can state a root cause or a ranked suspect list with the next test for each.

Week 6: You have flashed one device successfully with a written log, and your diagnostic decision tree covers six symptom classes.

Week 8: You have completed one full repair project and scored at least 70 percent on the mixed mock test with every error reviewed.
