Photosensitive Dry Film "PHOTEC"SL Series / DL Series for Direct Imaging

Image of SL Series / DL Series for Direct Imaging

SL series and DL series are fully aqueous applicable photosensitive films for direct imaging system.


SL-1800 Series

  • SL series are suitable for UV laser direct imaging system (light source: 355nm).
  • SL-1800 series are appropriate for forming HDI (High density interconnect) due to high photosensitivity, adhesion and resolution.
  • SL-1800 have good tenting property and make a contribution to high production yield.

SL-1900 Series

  • SL-1900 series have high photosensitivity (9~20mJ/cm2: recommended exposure energy, 355nm), excellent adhesion and resolution.
  • SL-1900 series excel especially in tenting property.

DL-9000 Series

  • DL series are suitable for direct imaging system (light sorce: 405nm).
  • DL-9000 series have high photosensitivity, excellent adhesion and resolution, threfore are appropriate for forming HDI.
  • DL-9000 series have excellent teting property over small diameter hole and make a contribution to high production yield.
