General Information

Introduction

Thank you for purchasing the PACE SODRTEK

model ST 300 Analog Convective Soldering/Desoldering System. This manual will provide you with the information necessary to properly set up, operate and maintain the ST 300.

Please read this manual thoroughly before using the unit. The ST 300 system 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.

ST 300 Handpiece

The user-friendly ST 300 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 pushpull action, allowing components to be lifted automatically after solder reflow. When utilized with the ThermoFlo System work platform, the handpiece is easily converted to a precision reflow head.

The ST 300 unit is available in either the 115 VAC or 230 VAC version. 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.

Safety

Safety Guidelines

The following are safety precautions that personnel must understand and follow when using or servicing this product.

“NOTE”

Used to indicate a statement of company recommendation or policy. The message may relate directly or indirectly to the safety of personnel or protection of property. NOTE is not associated directly with a hazard or hazardous situation and is not used in place of "CAUTION", "WARNING" or "DANGER".

“CAUTION”

Used to indicate a hazardous situation, which may result in minor or moderate injury. May also be used to alert personnel to conditions, procedures and practices which, if not observed, could result in damage to or destruction of the product or other equipment.

“WARNING”

Used to define additional information that if not closely followed might result in serious damage to equipment and represent a potential for serious personnel injury.

“DANGER”

Defines additional information that if not closely followed might result in severe personnel injury or death. Danger is not used for property damage unless personal injury risk is present.

Usage Warnings/Cautions

WARNINGS

1. A fire hazard may arise if the ST 300 is used improperly.

2. Do not use the ST 300 in the presence of an explosive atmosphere.

3. Be careful when using the ST 300 in places where there are combustible materials. Heat may be conducted to combustible materials which are out of sight.

4. Do not apply heat from the ST 300 to one place for a long time.

5. Do not leave the ST 300 unattended while powered on.

CAUTIONS

1. The ST 300 handpiece heater assembly housing and any installed nozzle are hot when the system is being cycled and for a period of time thereafter. DO NOT touch either the heater assembly housing, nozzle or direct heated air stream. Severe burns may result!

2. Always use the handpiece with the Heat Shield installed except when the handpiece is mounted to its work platform. The Heat Shield helps to prevent unintentional contact with the heater.
