Kappa 438 Laminates

Specifically formulated to have FR-4 matched dielectric constant (Dk),
design transition to Kappa 438 laminates will be effortless. These
laminates also exhibit low loss, tight Dk and thickness tolerances
needed to meet the growing performance needs of the wireless
market traditionally served by higher end FR-4 materials. Demand for
wireless data is growing exponentially, driving a need for substantially
higher levels of mobile network capacity and performance. FR-4 was
historically a material choice for many less demanding RF applications,
but changes in the wireless infrastructure related to growing
performance requirements, especially in small cells and carrier-grade
Wi-Fi, has resulted in instances where the properties of FR-4 are
lacking, and RF performance and consistency is compromised.

Wireless circuit designers can now realize a true breakthrough with
Kappa 438 laminates because they feature the performance of mid-tier
circuit materials that extend beyond performance limitations of FR-4,
and provide the optimum blend of price, performance, and reliability.
Kappa 438 laminates can be fabricated using standard epoxy/glass
(FR-4) processes and are compatible with conventional bondplies.
These laminates utilize RoHS compliant flame-retardant technology
to achieve a UL 94 V-0 flame retardant rating and are lead-free solder
process compatible. These materials conform to the requirements of
IPC-4103A, slash sheet /250.
