Low
Pressure Copper Pre-Preg
COUPLERTM
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.
