Arlon 65GT, 55ST, 55NT and 55RT laminate and prepreg systems are bad on DuPont's Thermount®, a nonwoven aramid (NWA) reinforcement, and are engineered to provide a unique combination of properties to the designer of HDI and SMT printed circuit boards. Arlon's epoxy NWA products are ideal for such diver applications as MCM-L, Fine Pitch SMT, BGA and Micro-BGA, and LCCC and offer design and performance advantages in a wide range of end us such as handheld phone boards and burn-in boards for IC testing.

When HDI Requirements Necessitate Surface Microvias
• Convenient Cost Effective Lar Microvia Formation
• Random Fiber Reinforcement Resists Resin Cracking
• Controlled Flow of Resin for Parallel Planar Surfaces
When Performance Criteria Demand CAF Resistance
• When Hole Spacing is Sized for sub 0.5 mm Pitch
• Random Fiber Aramid Reduces the Available Path for CAF
CAF (Conductive Anodic Filament) formation requires voltage bias, ionic residue and a physical
pathway. Nonwoven aramid laminates (picture above, right) do not provide the fiberglass “freeway”
(picture above, left) that is typical of woven glass constructions. In addition, Arlon has engineered the
65GT and 55ST resin systems using interpenetrating polymer network (IPN) technology to optimally
"saturate" the fibers, further limiting the possibility of conductive path growth along the fiber.
When SMT Requires Controlled Substrate CTE
• Tailorable CTE from near 6 ppm/ºC
• Smooth Surface Permits Fine Pitch SMT Designs
The ability to tailor CTE values of nonwoven aramid
systems to values as low as 6-9 ppm/ºC allows
attachment of a variety of SMT configurations with
minimal risk of solder joint failure caud by
device/substrate CTE mismatch.
Wh y U Arlon’s Epo xy Non wo ven Aramid Products?
Arlon's epoxy NWA products allow the formation of
cleaner (vs. FR-4) lar microvias in surface layers while
permitting the u of buried FR-4 signal bus layers in the
center. In many cas this results in greatly improved学校教学工作计划
interconnect density at reduced total cost, a key objective
in many applications, and particularly in mobile electronic
devices.

Laminate Availability
Arlon 65GT, 55ST, 55NT and 55RT epoxy nonwoven aramid products are available in thickness from 0.002" to 0.125" with 1/2 1 and 2 ounce copper foil standard. Other laminate thickness and special copper cladding (such as 1/4 ounce) may be available. Standard sheet size is 36" x 48" which yields standard 12 x 18 or 18 x 24 panels.
