Safety
Safety Guidelines
The following are safety precautions that personnel must understand and follow when using or servicing this product.
1.POTENTIAL SHOCK HAZARD - Repair procedures on PACE products should be performed by Qualified Service Personnel only. Line voltage parts may be exposed when the equipment is disassembled. Service personnel must avoid contact with these parts when troubleshooting the product.
2.To prevent personnel injury, adhere to safety guidelines in accordance with OSHA and other applicable safety standards.
3.Always use PACE systems in a well ventilated area. A fume extraction system such as those available from PACE are highly recommended to help protect personnel from solder flux fumes.
4.Exercise proper precautions when using chemicals (e.g., solder paste). Refer to the Material Safety Data Sheet (MSDS) supplied with each chemical and adhere to all safety precautions recommended by the manufacturer.
5.Do not contact the Heater or its peripheral parts during operation.
6.Once turned off, let the unit cool completely before contacting.
7.After use, verify that the amber indicator lamp is off.
8.When using Fluxes, use fume extraction equipment or use in a well-ventilated area to minimize operator exposure to fumes.
Preheating Basics
Preheating of a printed circuit assembly is normally required in the repair process whenever any one or more of the following situations exist.
1.Epoxy glass substrate with 4 or more layers.
2.Substrate with large ground planes.
3.Substrate of ceramic, polyimide or other high heat dissipative material.
4.Printed circuit assembly with large metal heat sinks.
Preheating of assemblies such as those listed above will accomplish the following objectives.
1.Minimize thermal shock by elevating the assembly temperature to a level closer to solder melt temperature.
2.Minimize the heat cycle reflow time.
3.Overcome the heat dissipation characteristics of the assembly.
4.Minimize adjacent melts on densely populated assemblies.
