TMM high frequency laminates are ideal for high reliability strip-line and micro-strip applications due to their electrical and mechanical stability. All dielectric variants can be produced as molded, 3-dimensional shapes. Shaped TMM components open up a new range of innovative design solutions for high or low frequency applications requiring controlled dielectric constant with low loss.


  • Wide range of dielectric constants (Dks)
  • Excellent mechanical properties, resists creep and cold flow
  • Exceptionally low thermal coefficient of Dk
  • Coefficient of thermal expansion matched to copper allowing for high reliability of plated through-holes
  • Available copper clad in larger formats, allowing the use of standard PCB subtractive processes
  • Resistant to process chemicals, no damage to material during fabrication and assembly processes
  • Thermoset resin for reliable wire bonding
  • No specialized production techniques required
  • TMM 10 and 10i laminates can replace alumina substrates
  • RoHS compliant, environment friendly
  • Third party metallization available
