StratEdge uses several unique processes to
build its ceramic packages. These depart radically
from other ceramic package manufacturers, but provide substantial
improvements in electrical performance of the final product.
Most companies use green tape, co-fired ceramic packages
for microwave applications. This limits performance, especially
at the higher frequencies, because green tape has inconsistent
shrinkage when it is fired.
StratEdge uses hardened, or post-fired, ceramic
that does not shrink, resulting in complete dimensional
stability and precise mechanical tolerances. StratEdge
then mates these ceramics with its patented electrical transition
designs to manufacture semiconductor packages with exceptionally
low electrical losses, even at frequencies as high as 50
GHz.
StratEdge also uses a molded ceramic/glass technology to
manufacture a series of hermetic
SMT packages. These packages provide an inexpensive
and short lead time alternative to conventional ceramic
package technology, particularly for new applications with
less than 1 million pieces per year. This same technology
is used to manufacture metal
packages with glass to metal seals.
