Printer Operation
The following are general guidelines for stencil printer optimization (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
Low Oxide Powder Distribution
Micron Size | Type | Pitch Requirements |
45 - 75μm | Type-2 | 24 mil and above |
25 - 45μm | Type-3 | 16 - 24 mil |
20 - 38μm | Type-4 | 12 - 16 mil |
15 - 25μm | Type-5 | 8 - 12 mil |
5 - 15μm | Type-6 | 5 - 8 mil |
2 - 11μm | Type-7 | < 5 mil |
Note: Type-6 and Type-7 may not be available in certain alloys. Other powder distributions are available on request.
Stencil Life
> 12 hours @ 30-45% RH and 20-25 °C
~ 4 hours @ 45-75% RH and 20-25 °C
Cleaning
No-clean solder paste that can be left on the board for many SMT assemblies. For applications requiring cleaning, the paste can be cleaned using commercial flux residue removers.
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 optimal 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!
