Printing
The print definition of RMA-223 is ideal for fine pitch applications. The stencil life of this RMA product virtually eliminates waste of solder paste. Consult the powder distribution chart to determine your mesh size requirements.
Printer Operation
The following are general guidelines for stencil printer optimization with RMA-223. 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 boards. Manual cleaning using 99% isopropyl alcohol (IPA) works well.
Storage and Handling Procedures
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.
