            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.
