So
you
think
you
have
the
copper
clad
board
out
from
its
packaging
and
then
you
set
it
flat
surface
and
then
you
carefully,
like
dimension
D
circuit,
so
that
you
have
a
line
where
you
want
to
cut
out
this
paper
board,
because
usually
you
don't
use
all
of
this
big
board.
Do
we
have
most
about
it
or
this?
Is
you
axel
axel?
That's.
A
You
said
that
you
want
to
cut
outside
of
the
work
working
edge
so
that
you
have
an
empty
gap
here
and
you
ensure
that
the
line
is
pretty
on
pretty
much
parallel
with
the
edge
of
the
table.
Then
you
put
a
piece
of
paper
not
about
the
glossy
paper,
but
just
a
piece
of
paper
over
here
such
that.
If
you
make
like
a
horizontal
stroke
accidentally
with
the
hacksaw,
you
don't
damage
the
copper
surface
and
then
you
proceed
to
hock
stolen,
come
on
clamp.

On
the
computer,
essentially,
we
want
to
one
example
of
a
workable
to
a
path,
is
use
ms
paint
and
make
the
etching
circuit
reversed
schematic,
and
then
you
take
that
and
put
it
onto
image
editor
and
edit
it
such
that
the
resolution
is
proper
because
evidently,
ms
paint,
when
you
print
it,
if
you
try
to
print
off
that
the
scaling
is
not
correct.
You
get
a
larger
circuit
than
what
is
actually
supposed
to
be
represented
on
the
software
board.
So
you
edit
the
picture
to
the
schematic
on.
Then
you
save
the
file.
A
D
B
B
A
It
cut
okay,
okay,
so
after
you've
got
the
circuit
circuit
Inc
on
the
velocity
paper,
you
have
to
cut
it
the
glossy
paper.
Similarly,
as
you
to
clap
board
except
night
to
distance
scissors,
so
now
you
buy
the
lines
that
you
can
see,
I'm
so
good.
You
just
cut
using
scissors
and
you
got
the
matching
dimension,
glossy
paper
with
the
ink
for
the
board.
Okay.
So
now
you
set
the
board
with
the
focus
on
the
working
surface.
Then
you
set.
A
Then
you
take
the
glossy
paper
that
has
the
ink
on
it,
and
if
this
is
the
paper-
and
you
have
the
ink
on
this
side,
then
you
take
that
and
you
lie
it
already.
A
copper
board
such
that
did
I
mention
is
like
the
dimension
correlation
that
the
external
promoter
is
like
near
perfect.
Then
you
take
small
pieces
of
tape
and
tape,
say
the
middle
of
two
or
three
sides
like
say:
ok,
just
standard.
B
A
D
C
Can
you
burn
through
too
much
like?
Can
you
actually
burn
it?
I,
don't
think
you
need
too
much
uh-huh.
What's
setting
on
iron
dudududu
hi
yea
high
as
it'll
go
and
dies,
it
will
go
and
that's
not
going
to
melt
the
board
or
anything
or
the
paper
like
I
mean
you'd
probably
want
to
stop
if
the
actual
papers,
starting
to
get
brown
right,
yeah.
C
A
Okay,
so
if
all
went
well,
then
the
toner
from
the
glossy
paper
should
have
been
transferred
completely
onto
the
copper
board,
but
the
glossy
paper
will
still
be
sticking
now
to
the
copper
board
through
d
toner
as
a
kind
of
adhesive.
So
you
have
this
copper
board.
Glossy
paper
combination
that
you
can
hold,
preferably
like
the
Garnett's
corners.
A
What
you
want
to
do
is
run
this
over
a
sink
of
our
running
water,
such
that
the
paper
gets
wet
and
after
that,
because
it's
get
because
it
got
stuck
because
the
paper
got
soggy.
You
can
just
scrape
it
off
your
finger
and
it's
important
that
you
get
all
the
glossy
paper
off.
Otherwise,
during
the
etching
process,
go
out,
the
Arctic
particles
or
small
pieces
of
the
glossy
paper
will
stop
the
etching
from
happening
at
certainly
did
that's
like
this
for
I
finished,
for
because
you
might
get
unwanted
connections
or
the
lack
of
connections.
Yeah.
B
A
After
the
glossy
paper
is
completely
removed
after
making
it
soggy,
and
then
you
have
a
board
with
toner
on
it
that
it
correlates
to
the
the
amount
of
material
you
want
left
after
the
copper
is
removed,
copper,
copper
board
with
ink
physically,
and
then
you
set
this
side
and
you
begin
to
prepare
the
etching
container
mm-hmm.
So
this
is
glass,
and
can
you
slide
your
container
for
larger
boards
if
necessary,
and
this
is
P
PCB
etchant
solution
and
it
contains
ferric
chloride,
ferrous
chloride
and
hydrochloric
acid.
