High-quality tacky flux (Amtech or Kingbo), leaded solder wire (63/37 alloy), low-melt solder (for easy component removal), desoldering braid (wick), and 99% Isopropyl Alcohol (IPA). 2. Understanding Motherboard Architecture and Power Rails
Everything works except one specific function. Culprit: ESD protection diodes (small 4-pin or 6-pin ICs near the port). Repair: Desolder the ESD chip. If the port works after removal, the ESD chip was shorted. Note: Do not leave it permanently removed; replace it.
