Selective Soldering System with Built-in Spray Fluxer

Designed For Use with Multilayer and High Density PCBs

The STS-2533SJ is a new Selective soldering system equipped with a Servo Jet Spray Fluxer system.

The Servo Jet system allows for precise flux application on small targets and through hole components.

XYZ-Programmable solder wave from a special nozzle allows users to make lead soldering easy and accurate.
