Smartphone and Tablet Repair Course

Lesson 1 • Battery and Power Systems

Covers lithium-ion and lithium-polymer cell chemistry, capacity ratings, and charging circuits. Grounds students in power concepts critical for safe repair.

Lesson 2 • Connectivity and Communication Hardware

Surveys cellular, Wi-Fi, Bluetooth, and NFC hardware components. Links hardware knowledge to signal and connectivity diagnostics covered in later chapters.

Lesson 3 • Display and Touch Technologies

Explains LCD, OLED, and AMOLED panel technologies alongside capacitive touch systems. Connects display knowledge to common failure modes addressed later.

Lesson 4 • Mobile Device Categories and Ecosystems

Covers major device form factors, operating system families, and manufacturer ecosystems. Establishes the landscape technicians encounter daily in repair work.

Lesson 1 • Soldering and Rework Equipment

Introduces soldering stations, hot-air rework guns, and flux types used in board-level repair. Prepares students for the soldering skills taught in later chapters.

Lesson 2 • Electrostatic Discharge Prevention

Explains ESD damage mechanisms and protective measures for sensitive components. Proper ESD practice is compulsory before any hands-on disassembly work.

Lesson 3 • Essential Hand Tools for Device Repair

Identifies screwdrivers, spudgers, pry tools, and opening picks required for mobile repair. Correct tool selection prevents cosmetic and structural damage.

Lesson 4 • Diagnostic and Measurement Instruments

Covers multimeters, DC power supplies, and USB protocol analysers used in fault diagnosis. Instrument proficiency underpins every diagnostic workflow in the course.

Lesson 1 • Adhesive and Clip Fastener Management

Covers heat-softening adhesives, prying clip sequences, and re-adhesion methods. Mastery here prevents cracked frames and failed seals during reassembly.

Lesson 2 • Reading Service Manuals and Teardown Guides

Teaches interpretation of OEM service documentation, exploded diagrams, and torque specs. Accurate guide reading prevents assembly errors and component damage.

Lesson 3 • Connector and Cable Handling

Explains ZIF, LIF, and board-to-board connector types and safe disconnection methods. Proper technique prevents torn flex cables and broken connector locks.

Lesson 4 • Full Device Teardown Practice

Applies all prior disassembly skills in a structured, timed teardown of a complete device. Students document each step and verify correct reassembly function.

Lesson 1 • OLED Burn-In and Calibration

Addresses OLED-specific issues including burn-in, colour shift, and brightness calibration after replacement. Proper calibration ensures customer satisfaction with the repaired display.

Lesson 2 • Diagnosing Display Failures

Identifies cracked glass, dead pixels, backlight failure, and touch dropout symptoms. Accurate diagnosis determines whether glass-only or full assembly replacement is needed.

Lesson 3 • Quality Control and Customer Verification

Establishes post-repair testing protocols for display uniformity, touch accuracy, and seal integrity. Structured QC prevents callbacks and builds customer trust.

Lesson 4 • Full Display Assembly Replacement

Guides complete removal and installation of display assemblies including flex transfer. Correct transfer of small components prevents functional loss after replacement.

Lesson 1 • Post-Replacement Power Validation

Validates charging speed, battery percentage accuracy, and thermal behaviour after replacement. Thorough validation confirms the repair meets safety and performance standards.

Lesson 2 • Charging Circuit Diagnostics

Diagnoses charging IC faults, damaged charge ports, and PMIC failures using a bench supply. Isolating the fault layer prevents unnecessary component replacement.

Lesson 3 • Battery Health Assessment

Uses built-in diagnostics and third-party tools to evaluate cycle count, capacity, and impedance. Accurate assessment justifies replacement and sets customer expectations.

Lesson 4 • Safe Battery Removal Procedures

Covers adhesive pull-tab removal, prying techniques, and puncture-prevention practices. Safe removal eliminates fire and chemical exposure risk from damaged cells.

Lesson 1 • Microphone and Vibration Motor Service

Covers microphone element testing and vibration motor replacement on flex and board-mounted designs. These components affect call quality and haptic feedback customer experience.

Lesson 2 • Headphone Jack and Speaker Repair

Diagnoses and replaces headphone jack assemblies and speaker modules on applicable devices. Audio output restoration requires careful flex routing and acoustic seal integrity.

Lesson 3 • Power and Volume Button Repair

Addresses stuck, unresponsive, and physically broken power and volume button assemblies. Restoring tactile button function is among the most common customer repair requests.

Lesson 4 • Charging Port Flex Replacement

Covers removal and installation of modular charge port flex assemblies on common platforms. Modular replacement is the fastest path to restoring charging on most devices.

Lesson 1 • Diagnosing Camera Failures

Identifies blurry images, black screen, autofocus failure, and OIS rattle as distinct fault types. Each symptom maps to a specific hardware layer for targeted replacement.

Lesson 2 • Front Camera Module Replacement

Guides removal and installation of front-facing camera modules including Face ID sensor arrays. Sensor alignment is critical for biometric authentication to function post-repair.

Lesson 3 • Camera Lens and Glass Repair

Addresses cracked rear camera glass replacement without disturbing the module beneath. Lens glass repair is a high-margin, low-risk service when performed correctly.

Lesson 4 • Rear Camera Module Replacement

Covers single, dual, and triple rear camera module swaps including periscope telephoto units. Correct module seating prevents autofocus and OIS calibration errors.

Lesson 1 • Jumper Wire and Trace Repair

Addresses lifted pads, broken traces, and via damage using jumper wire and conductive epoxy. Trace repair salvages boards where component replacement alone cannot restore function.

Lesson 2 • Fault Isolation with Measurement Tools

Uses multimeter diode mode, resistance mapping, and bench supply current profiling to locate faults. Systematic measurement eliminates guesswork and reduces unnecessary component removal.

Lesson 3 • SMD Component Removal and Replacement

Covers hot-air and soldering iron techniques for removing and replacing 0201, 0402, and larger SMD parts. Precise temperature control prevents pad and trace damage.

Lesson 4 • Reading Schematics and Board Maps

Teaches schematic symbol interpretation, net tracing, and board-view software navigation. Schematic literacy is the foundation of every board-level diagnostic workflow.
