YIZHUO
has
been
participated
in
all
kinds
of
LED
lighting
projects,
by
supplying
LED
PCB(
LED
circuit
board)
with
using
CEM3,
FR4,
aluminum,
and
copper
alloy
as
the
LED
PCB
base
material.
There
is
no
doubt
that,
compare
to
CEM
3and
FR
4
material,
aluminum
and
copper
alloy
have
better
performance
on
heat
transfer,
however,
since
copper
alloy
price
is
much
higher
than
aluminum,
so
we
can
say.
in
the
LED
lighting
industry,
aluminum
is
absolutely
the
most
economic
option
considering
thermal
conductivity.
rigidness,
and
cost.
