TAIYO PSR-4000BN Series LIQUID PHOTOIMAGEABLE SOLDER MASK Screen or Spray Application Available in Green or Dark Green Semi-Gloss Finish RoHS Compliant High Viscosity version for improved edge coverage on High Traces Compatible with Lead-Free Processing Best In Class for Small Hole Clearing Wide Processing Window Fine Dam Resolution Withstands ENIG & Immersion Tin Revised March 2005 Page 2 of 6 PROCESSING PARAMETERS FOR PSR-4000BN SERIES PSR-4000BN Series includes PSR-4000BN, PSR-4000BN (HV), and PSR-4000BN (DG). They are two-component, alkaline developable LPI solder mask products for flood screen and spray application methods. The products are designed to be user friendly with wide processing latitudes, low odor, fast developing and good resistance to alternate metal finishes such as ENIG and immersion Tin while maintaining dams of 3 mils or less. The PSR-4000 BN (HV) provides improved edge coverage over high circuits while the PSR4000BN (DG) provides the same benefit in a Dark Green color. PSR-4000BN Series meets or exceeds the requirements of IPC SM-840C Class H and Class T, Bellcore GR78-CORE Issue 1, and has a UL flammability rating of 94V-0. All Taiyo America products comply with the Directive 2002/95/EC of the European Parliament and of the Council of 27 January 2003 on the Restriction of the use of certain Hazardous Substances (RoHS) in electrical and electronic equipment.
