Selective soldering involves soldering THT (through hole technology) components on printed circuit boards heavily populated with SMD’s (surface mounted components). This process is used when wave soldering is not possible and the alternative is labour intensive hand soldering.

The ERSA Versaflow is the industry benchmark, used by many blue chip OEM and CEM companies in UK such as BAe Systems, Rolls Royce and MBDA.

ERSA selective soldering machines include the Versaflow, Ecoselect and Smartflow range of machines.
