High Tg Glass Epoxy Multilayer Material <MCL>

MCL-E-679 ・ GEA-679N <prepreg>

These FR-5 equivalent materials offer increased Tg (175 TMA) and improved through-hole reliability. minimal water absorption rates of less than 50% of conventional FR-4s, these materials use advanced resin technology to offer superior CAF restraining property and better It is suitable for the substrate of plastic BGA. .


  • High Tg & excellent through hole reliability
  • Superior moisture resistance and good insulation resistance
  • High heat resistance after water absorption
  • Good processability(for drilling punching)
