Printer Operation
The following are general guidelines for stencil printer optimization with 4300. Some adjustments may be necessary based on your process requirements.
Print Speed: 25-100 mm/sec
Squeegee Pressure: 70-250g/cm of blade
Under Stencil Wipe: Once every 10-25 prints, or as necessary

Storage
Solder paste should be stored between 3-8°C (37-46°F) to obtain the maximum refrigerated shelf life of six months. Unopened solder paste stored at room temperature, 25°C (77°F) will have a one-month shelf life. Syringes and cartridges should be stored vertically in the refrigerator with the dispensing tip down. Allow 4-8 hours for solder paste to reach an operating temperature of 20-25°C (68-77°F). Keep the solder paste container sealed while warming the solder paste to operating temperature. NEVER FREEZE SOLDER PASTE.
