General Information
Introduction
Thank
you for purchasing the PACE SODRTEK
Soldering/Desoldering System.
properly set up, operate, and maintain the ST 325. Please read this manual thoroughly before using
the unit. The ST 325 unit is a complete system designed for hot air removal and installation of SMD
components, including Ball Grid Arrays (BGAs). The following key features allow process controlled
placement and reflow of BGAs and SMD components. The ST 325 will store up to 20 profiles on its
own. A PC can be used to store additional profiles and to collect the thermocouple data.
Microprocessor Control
The microprocessor system offers precision control of temperature (closed-loop control), cycle time
(adjustable by one second increments), and blower speed provides consistent, repeatable results in
successive reflow operations. Utilizing the Quiet Flo (low noise) turbine blower, pressure/flow rate is
easily controlled and maintained at optimum levels for the particular task. A multi-level password
lock-out prevents unauthorized changes and an audible countdown timer indicates end of cycle.
ST 325 Handpiece
The user-friendly ST 325 static-safe handpiece incorporates a powerful heater and has easy-access
heat cycle and vacuum pick switches on the handle. A built-in, self-adjusting vacuum pick has a push-
pull action, allowing components to be lifted automatically after solder reflow. When utilized with the
ST 325 System work platform, the handpiece is easily converted to a precision reflow head.
The ST 325 unit is available in either the 115 VAC or 230 VAC version. The 115 VAC version system
bears the FCC Conformity Marking which assures the user that it conforms to all the requirements of
FCC Emission Control Standard, Title 47, Subpart B, Class A. This standard is designed to provide
reasonable protection against harmful interference when the equipment is operated in a commercial
environment. The 230 VAC version system bears the CE Conformity Marking which assures the user
that it conforms to all the requirements of (EU) directive EMC 89/336/EEC & 73/23/EEC.
