: Clear the remaining old solder using a desoldering wick until the footprint is completely flat.
Electrostatic Discharge (ESD) can instantly destroy sensitive silicon chips. Always wear an anti-static wrist strap and work on an ESD-safe mat.
High-quality flux is essential for clean, strong solder joints. Isopropyl Alcohol (IPA) is required to remove residue after repairs. 2. Essential Techniques Using Your PCB Repair Tools
: Effortlessly track electrical paths between components that are hidden within multi-layer boards.
A critical but often overlooked tool, the preheater warms the entire PCB from underneath before a technician applies localized heat. This reduces the thermal gradient (the difference in temperature between the area being soldered and the rest of the board), minimizing the risk of warping or "popcorning" (moisture expansion inside the PCB layers).
