Low-Cost Convective and Infrared System for SMT Rework

ST-PH Combo System nozzle applicationThe ST 925 combines three popular PACE products together into one convenient, low-cost SMT Rework System. The system is comprised of the ST 325 Programmable Convective/Hot Air Rework Station, the PH 100 Low Profile Infrared Preheater and ST 500A Z-Axis Platform. Together, the system provides a powerful 575 Watt convective top-side heater plus a 1600 Watt IR bottom-side preheater which allows operators to safely rework PCBs for fast, efficient soldering, rework or repair, even on the highest mass, thermally challenging, lead-free PCBs.

Fully Programmable, Self-Contained Convective/Hot Air Station

The ST 925 features a self-contained convective/hot air SMT rework station that is fully programmable and can be used to remove and install surface mount components. From the front panel, the system can be used in either manual or “timed” modes. Manual mode means that the system generates heated airflow when the cycle button is pressed; when it is pressed a second time the system shuts off. “Timed” modes allow the operator to create up to 20 “Profiles” that consist of time and temperature parameters to ensure process control and repeatability. The system uses a pump to generate airflow that first passes through a heater, where it is warmed to the appropriate temperature, and then through optionally available heat-focusing nozzles that “shape” the air stream for the specific component. A user-friendly front panel interface with Digital Display allows for easy adjustment of temperature, flow rate and timing and intuitive programming and profile development. A unique adapter allows instant change out of Nozzles, without tools. Over 80 low-cost Nozzles are available for a wide variety of surface mount components.
