What is an SMD LED PCB Board?
SMD
stands
for
Surface
Mount
Device.
Surface
mount
technology
(SMT)
has
almost
replaced
the
through-hole
technology.
However,
through-hole
technology
is
still
used
for
the
components
that
cannot
be
surface
mounted.
Therefore,
Surface
Mount
LED
PCB
is
very
popular
SMDs
are
compact
components
that
can
be
directly
placed
over
the
PCB.
There
is
no
need
for
a
hole
because
the
components
do
not
have
leads
or
might
have
small
leads.
There
are
only
small
contacts
at
the
ends
of
the
device
that
are
used
to
make
connections.
Consequently,
the
PCBA
is
very
compact.
SMDs
are
soldered
using
reflow
soldering.
At
first,
the
solder
paste
is
applied
to
the
bare
board.
Then,
the
components
are
picked
and
placed
in
the
desired
place.
Finally,
the
board
is
passed
through
a
reflow
oven,
and
the
components
are
directly
mounted
without
any
hassle.
An
SMD
LED
PCB
board
contains
SMD
LEDs
that
are
more
compact
than
their
through-hole
equivalents.
SMD
LEDs
are
widely
used
nowadays.
They
provide
higher
lumen
output,
which
improves
the
level
of
illuminance
in
the
area.
They
are
more
efficient
and
brighter.
This
is
the
reason
SMD
LED
PCB
boards
are
preferred.
