TODAY'S TIP — MOBILE PHONE REPAIR
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.

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 → go straight to the thermal camera. Diagnosis drops from 2 hours to 20 seconds!

Soldering Tips for 2026 Boards:
- Use No-Clean flux — zero corrosive residue, safe for deep board work
- Keep 138°C Low-Melt Solder for heat-sensitive components
- Use Cartridge-style soldering tips — better accuracy, no torn pads

RF4 Thermal Camera on Mobile Board:━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ TODAY'S TIP — LAPTOP REPAIR Diagnosing Overheating Laptops Step by Step

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

Step 2 — Software diagnosis:- Use HWMonitor or ThrottleStop to check CPU temps live- Temps spiking above 90°C under light load = serious problem
Step 3 — 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 damaged
Pro Tip: Dust buildup is the #1 silent killer of laptops. Tell every customer to clean every 6 months!━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
