Procedure
Theory
An SMD Rework Station is a tool used for performing intricate reworks and repairs of broken or off - kilter
electronic components. It makes surface-mount soldering more manageable and faster. Here are some key
features and accessories:
Key Features:
Hot Air Generation: The station can generate hot air temperatures needed to melt metal for reworks1.
Air Flow Grade: A dial on the main hardware adjusts the rate of hot air flowing from the hand tool1.
Temperature Control: Allows operators to adjust the temperature from the lowest to the highest range1.
Hot Air Wand: A handheld tool used to apply heat to metal solder1.
Wand Holder: A place to keep the wand when it’s not in use1.
Essential Accessories:
Nozzle Tips: Compatible with the station’s brand model1.
Solder: Used for repairing metal1.
Tip Cleaner: For constant tip maintenance1.
Flux: A liquid solution used for cleaning oxides and impurities from metal surfaces1.
SMD Tweezers: Help operators pick up small components without touching them1.
ESD Table Mat & Wrist Strap: Protect components from harmful static discharge1.
These stations are available from various manufacturers and suppliers, with prices varying based on features
and brand3.
