Learn How to Solder SMD in this Detailed Surface Mount Soldering Guide.

SMD Soldering and Desoldering is little different from thru-hole Soldering and Desoldering Process.
SMD Desoldering is generally done using a Hot Air Blower while Soldering can be done using a soldering iron and solder wire or using solder paste or solder balls (BGA) and SMD Hot Air Blower / rework station.

There are many process for surface mount soldering for SMD Components but none is perfect for all applications.
Types of SMD Soldering Process
All SMD soldering processes have technical concerns and there are ways to resolve those concerns. Because it offers higher yield and lower operation cost, convection dominant IR soldering has evolved as the preferred process for reflow soldering.

Vapor phase soldering will not disappear but will continue to be used in niche applications. For some specialized jobs, other reflow soldering processes such as laser and hot bar resistance soldering are also used.
These soldering processes are intended not to replace either vapor phase or IR but to complement them. The process ultimately used should be selected on the basis of the specific requirements of the intended application, the solder defect results, and the overall cost.
