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

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


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.


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.
