Mobile Repair Course

Lesson 1 • Workplace Safety and ESD Prevention

Establishes safe handling practices for electrostatic discharge and chemical hazards. Prevents component damage and personal injury throughout the course.

Lesson 2 • Core Hardware Components Overview

Identifies internal components including processors, memory, and batteries. Provides the anatomical map needed before any disassembly work begins.

Lesson 3 • Reading Schematics and Service Manuals

Teaches interpretation of circuit diagrams, exploded views, and manufacturer documentation. Accurate schematic reading underpins every diagnostic and repair decision.

Lesson 4 • Mobile Device Types and Ecosystems

Covers smartphones, tablets, and feature phones across major platforms. Establishes baseline vocabulary for all subsequent repair topics.

Lesson 1 • Connector and Cable Handling

Addresses ZIF, FPC, and board-to-board connector types and safe disconnection methods. Mishandled connectors are a leading cause of secondary damage.

Lesson 2 • Battery Removal and Safe Disposal

Covers adhesive pull-tab techniques, swollen battery protocols, and disposal regulations. Safe battery handling prevents fire and chemical exposure risks.

Lesson 3 • Display and Frame Separation

Teaches safe screen removal using suction cups, picks, and controlled heat. This skill is prerequisite for most internal component access procedures.

Lesson 4 • Reassembly Quality Checks

Establishes post-reassembly verification steps including fit, function, and waterproofing tests. Systematic checks reduce callback rates and ensure customer satisfaction.

Lesson 1 • Front Camera and Earpiece Integration

Covers transfer of earpiece mesh, front camera, and proximity sensor to replacement screens. Omitting these steps causes functional failures after display repair.

Lesson 2 • Digitizer Separation and Rebonding

Teaches glass-only digitizer separation using UV adhesive and OCA film. This advanced skill reduces part cost compared to full assembly replacement.

Lesson 3 • Diagnosing Display Faults

Identifies dead pixels, backlight failure, ghost touch, and cracked digitizers through visual and software tests. Accurate diagnosis prevents unnecessary part replacement.

Lesson 4 • Screen Replacement Procedures

Guides full screen assembly replacement including adhesive application and calibration. Correct procedure ensures optical clarity and touch accuracy post-repair.

Lesson 1 • Charging Port Diagnosis and Repair

Identifies bent pins, debris blockage, and board-level charging IC faults. Charging port issues are among the most frequent customer complaints.

Lesson 2 • Battery Health and Capacity Testing

Uses diagnostic software and multimeters to assess cycle count, capacity, and internal resistance. Accurate health data justifies replacement recommendations to customers.

Lesson 3 • Wireless and Fast Charging Systems

Covers Qi wireless coil inspection and fast-charge protocol compatibility issues. These systems require specific diagnostic steps distinct from wired charging faults.

Lesson 4 • Power Management IC Fundamentals

Introduces PMIC functions including voltage regulation and power sequencing. Understanding PMIC behaviour is essential for advanced board-level fault tracing.

Lesson 1 • Camera Module Diagnosis

Identifies autofocus failure, image blur, and OIS malfunction through software and visual inspection. Camera faults are high-value repairs requiring precise diagnosis.

Lesson 2 • Vibration Motor and Haptic Engine Service

Covers eccentric rotating mass and linear actuator motor types and their replacement. Haptic feedback quality directly affects perceived device premium.

Lesson 3 • Proximity, Gyroscope, and Accelerometer Faults

Uses diagnostic apps to isolate sensor failures affecting screen auto-off, orientation, and navigation. Sensor faults are frequently misdiagnosed as software issues.

Lesson 4 • Speaker and Microphone Repair

Diagnoses distorted audio, no-sound faults, and microphone dropout using tone generators and apps. Audio faults often involve mesh blockage before component failure.

Lesson 1 • IC and BGA Rework Procedures

Addresses removal, reballing, and replacement of BGA chips including charging ICs and PMICs. BGA rework is the highest-skill soldering task in mobile board repair.

Lesson 2 • SMD Component Removal and Replacement

Covers resistor, capacitor, and diode removal and placement using hot air and iron techniques. Precision placement on mobile boards requires steady hand and correct tool settings.

Lesson 3 • Soldering Station Setup and Technique

Covers hot air station, soldering iron, and flux selection for mobile board work. Proper setup prevents thermal damage to adjacent components during rework.

Lesson 4 • Component Identification and Sourcing

Teaches reading component markings, datasheets, and sourcing verified replacement parts. Correct identification prevents installation of incompatible or counterfeit components.

Lesson 1 • Wi-Fi and Bluetooth Fault Diagnosis

Isolates weak signal, no-connect, and dropout faults using signal strength tools and hardware inspection. Distinguishes antenna damage from module failure accurately.

Lesson 2 • GPS and Location System Repair

Diagnoses poor GPS lock, location drift, and no-fix faults through antenna and software testing. GPS accuracy is critical for navigation and location-based applications.

Lesson 3 • NFC and UWB Module Service

Covers NFC coil inspection, UWB chip identification, and contactless payment fault diagnosis. These modules require careful handling due to proximity to other antennas.

Lesson 4 • Antenna System Architecture

Maps antenna placement for cellular, Wi-Fi, Bluetooth, and NFC within device chassis. Antenna knowledge prevents accidental damage during unrelated repairs.

Lesson 1 • Data Recovery Fundamentals

Introduces file system recovery tools and backup restoration for common data loss scenarios. Data recovery skills add significant value to a repair technician's service offering.

Lesson 2 • Diagnostic App and Software Tools

Uses hardware diagnostic apps to test sensors, displays, and connectivity in structured sequences. Software tools accelerate fault isolation before physical disassembly.

Lesson 3 • Factory Reset and Data Wipe Procedures

Teaches hard reset methods via recovery menu and software tools with data implications. Proper reset procedures resolve software faults while managing customer data responsibly.

Lesson 4 • Boot Process and Failure Analysis

Maps the boot sequence from power-on to OS load and identifies failure points at each stage. Boot fault analysis prevents unnecessary hardware replacement.
