Low Dissipation Factor, High Heat Resistance Multilayer Material

MCL-LX-67Y ・ GXA-67N <prepreg>

"Type No. MCL-LX-67Y" is high heat resistance multilayer material, which indicates low dielectric constant and low dissipation factor in GHz range of frequency, and also the processing characteristics are close to conventional FR-4. It is suitable for high frequency circuit board of cellular phone base station in the wireless communication market.


  • Low transmission loss in GHz range of frequency (about 40% of FR-4)
  • Drift of its dielectric properties is small. (frequency dependence, temperature dependence, after water absorption)
  • High Tg, low water absorption, high heat resistance
