Gripping & Placer Tools: How to utilize straight and curved ESD-safe tweezers to safely disconnect fragile ZIF (Zero Insertion Force) and coaxial cable connectors.
This section transitions the user from basic mechanical teardowns to logical troubleshooting when a phone won’t turn on or charge.
Digital Multimeter (DMM): Step-by-step instructions on setting up the meter for DC voltage testing (checking battery and charging port output) and continuity/diode mode (hunting for short circuits).
DC Power Supply: How to boot a phone motherboard without a battery attached, interpreting current draw (Amperage) to diagnose power management failures.
USB Ammeter / Tester: Utilizing an inline USB safety tester plugged into the charging block to instantly diagnose if a phone is pulling normal current ($1A$ to $2A$) or completely dead ($0A$).
For advanced users handling board-level fixes like swapping out charging ports, audio IC chips, or FPC connectors.
Soldering Iron Stations: Temperature calibration tips, tip selection (chisel vs. conical), and maintenance/tinning procedures.
Hot Air Rework Stations: Managing the delicate balance of air flow and temperature to safely desolder multi-pin components without blowing adjacent surface-mount resistors off the board.
Chemical Consumables: Proper application of rosin flux (to clean joints and fluidize solder), solder wick (braided wire to remove old solder), and low-melt solder alloys.
The final step is cleaning up the internal cavity and sealing the device back up to its original structural integrity.
Chemical Cleaners: Safe usage of 99% Isopropyl Alcohol (IPA) to dissolve old glue residues, flux oils, and clean mild liquid damage.
Liquid Adhesives vs. Tape: Instructions on applying specialized acrylic glues (like B-7000) versus applying precision-cut double-sided adhesive gaskets.
Camping and Curing: Utilizing specialized display repair clamps to apply even, steady pressure while the new adhesives cure over 15 to 30 minutes.
