Printing

The print definition of NC-560-LF is ideal for fine pitch applications. The stencil life of this no-clean product virtually eliminates waste of solder paste. This type 3 solder paste will meet pitch requirements from 16 mil to 24 mil.

Printer Operation

The following are general guidelines for stencil printer optimization with NC-560-LF. Some adjustments may be necessary based on your process requirements:

  • Print Speed: 25–100mm/sec
  • Squeegee Pressure: 0.2–0.7kg/inch of blade
  • Under Stencil Wipe: Once every 10–25 prints or as necessary

Stencil Cleaning

Automated stencil cleaning systems for both stencil and misprinted printed circuit boards. Manual cleaning using 99% isopropyl alcohol (IPA) works well.

Storage and Handling

  • Refrigerated storage at 42–47°F will prolong the solder paste shelf life to no less than 6 months
  • Syringes & cartridges should be stored vertically with the dispensing tip down.
  • Solder paste should be allowed to reach ambient temperature naturally, prior to use (about 6-8 hours)
  • Never freeze solder paste.

Heating
