Low Pressure Copper Pre-Preg

Coupler is a novel organic copper-clad laminate that is available with 40-50 micron molecularly flexible dielectric and as thin 1/4 oz copper layer for ultra-thin components and boards.

AIT patented (US patent#7,154,046; 6,717,819; 6,580,035; 6,581,276; 6,108,210; 6,297,564; 6,665,193; 6,973,716)) flexible circuit substrates (FCS) are organic copper-clad laminate that differs from traditional FCS in two fundamental aspects to give them the unparalleled reliability performance:

  • Instead of polyimide-adhesive or vacuum deposited copper laminates, its uses AIT proprietary flexible hydrophic dielectric insulating layer resulting in stress-free and high speed circuits and interconnections.
  • Unparalleled high temperature stability to withstand soldering at 300°C.
  • Multi-layer capability with the same flexible dielectric copper pre-preg that can be laminate at low pressure of less than 14 psi and 125°C or higher.
  • Thinner pre-preg are available in rolls of 24-inch width.
  • Thicker pre-preg are available in sheets of 24-inch by 24-inch.
  • Ideal for flexible circuits, fine-pitch interposers, power and LED components, modules.
