to target heat to individual components without dislodging other SMT parts by way of eddies air currents.
Adopt infrared weld technology which independent exploration, infrared penetration strength, components uniform heating, beyond the traditional hot air heating vowed to prevent blow off the IC surrounding small components.
Technician focused infrared heat is easy to target most component removal/replacement and re-work.
Infrared heat source bulbs are long-lived, un-expensive and
