πŸ“± TODAY'S TIP β€” MOBILE PHONE REPAIR
πŸ”₯ Find Short Circuits in Seconds Using a Thermal Camera






Still spending hours hunting for a short on a dead board? In 2026, that method is old-school.

βœ… Pro Workflow:
1. Connect dead board to your DC Power Supply
2. Inject voltage into the board
3. Point your thermal camera (QianLi / RF4 / IIT ShortCam) at the board
4. The faulty capacitor or IC will GLOW with heat on your screen in real time

⚑ Key Rule: If a phone pulls HIGH CURRENT but shows NO signs of life β†’ go straight to the thermal camera. Diagnosis drops from 2 hours to 20 seconds!

πŸ› οΈ Soldering Tips for 2026 Boards:

- Use No-Clean flux β€” zero corrosive residue, safe for deep board work
- Keep 138Β°C Low-Melt Solder for heat-sensitive components
- Use Cartridge-style soldering tips β€” better accuracy, no torn pads

Overheating is the #1 laptop complaint in every repair shop. Here is the correct workflow:πŸ”
Step 1 β€” Check basics first:
- Fan spinning? Any blocked vents?- Dusty heatsink? (most common cause β€” check this first!)- Thermal paste dried out?πŸ”

Step 2 β€” Software diagnosis:
- Use HWMonitor or ThrottleStop to check CPU temps live- Temps spiking above 90Β°C under light load = serious problemπŸ”
Step 3 β€” Hardware fix:
- Clean fans and vents with compressed air- Replace thermal paste on CPU and GPU chips- Faulty fan? Replace immediately before the board gets damagedπŸ’‘
Pro Tip: Dust buildup is the #1 silent killer of laptops. Tell every customer to clean every 6 months!
