background image

Please

 

note,

 

that

 

plotted

 

image

 

is

 

in

 

plotting

 

area

 

rotated

 

by

 

270

 

degree

 

(or

 

–90

 

degree)

 

and

 

mirrored

 

from

 

some

 

programming

 

reasons.

 

It

 

means,

 

X

 

axis

 

of

 

the

 

grey

 

plotting

 

area

 

represents

 

Y

 

axis

 

of

 

the

 

film

 

loaded

 

in

 

photoplotter

 

(drum

 

circumference),

 

while

 

Y

 

axis

 

of

 

the

 

grey

 

plotting

 

area

 

represents

 

X

 

axis

 

of

 

the

 

film

 

loaded

 

in

 

photoplotter

 

(drum

 

axis).

 

At

 

the

 

same

 

time

 

the

 

image

 

is

 

mirrored

 

over

 

the

 

Y

 

axis

 

of

 

the

 

plotting

 

area.

 

This

 

has

 

no

 

impact

 

on

 

proper

 

photo

plotting,

 

as

 

the

 

overall

 

size

 

of

 

the

 

plotted

 

image

 

is

 

the

 

same.

  

 

To

 

avoid

 

confusion

 

with

 

plot

 

rotation

 

on

 

the

 

film,

 

this

 

is

 

the

 

rule:

 

horizontal

 

line

 

of

 

the

 

plotted

 

image

 

will

 

be

 

vertical

 

in

 

plotter.

Gerber

associated

 

with

 

the

file.

 

The

 

master

 

Gerber

 

file(s)

 

can

 

be

 

located

 

anywhere

 

inside

 

the

 

plotting

 

area,

 

usually

 

on

 

layer

 

(film)

 

number

 

1

 

(default),

 

while

 

associated

 

Gerber

 

files

 

are

 

automatically

 

positioned

 

under

 

Master

 

Gerber

 

on

 

different,

 

specified

 

layers

 

(films).

 

If

 

Master

 

Gerber

 

file

 

is

 

for

 

example

 

top

 

side

 

routing

 

of

 

the

 

PCB,

 

then

 

Associated

 

Gerber

 

files

 

are

 

for

 

example

 

silkscreen,

 

soldermask

 

or

 

bottom

 

side

 

routing

 

of

 

the

 

same

 

board

 

 

they

 

will

 

be

 

in

 

same

 

location

 

as

 

the

 

Master

 

image,

 

but

 

on

 

different

 

layers

 

(films),

 

even

 

when

 

penalization

 

is

 

done.

 

Several

 

Master

 

Gerber

 

files

 

(same

 

or

 

different)

 

can

 

be

 

loaded

 

on

 

one,

 

same

 

layer

 

(film).

 

Associated

 

Gerber

 

files

 

are

 

loaded

 

into

 

selected

 

layer,

 

which

 

can

 

be

 

selected

 

in

 

top

 

right

 

window

  

 

Active

 

Layer.

 

 

Note:

 

The

 

meaning

 

„Master

 

Gerber

 

 

and

 

„Associated

 

Gerber“

 

makes

 

sense

 

only

 

in

 

case

 

of

 

several

 

artworks

 

(like

 

Top

 

side

 

routing,

 

Bottom

 

side

 

routing,

 

Silkscreen,

 

Soldermask,

 

etc.)

 

from

 

the

 

same

 

board

 

will

 

be

 

photo

plotted,

 

while

 

one

 

of

 

them

 

(Master)

 

will

 

be

 

panelised

  ‐

the

 

other

 

ones

 

(Associated)

 

must

 

be

 

then

 

be

 

panelised

 

too

 

and

 

be

 

positioned

 

exactly

 

to

 

the

 

same

 

location

 

as

 

the

 

Master

 

image.

 

If

 

films

 

are

 

not

 

panelised,

 

than

 

every

 

Gerber

 

file

 

can

 

be

 

considered

 

as

 

„Master

 

Gerber“,

 

as

 

it

 

can

 

be

 

positioned

 

anywhere

 

in

 

plotting

 

area

 

without

 

considering

 

another

 

Gerber

 

files.

  

 

If

 

standard

 

Gerber

 

file

 

is

 

loaded

 

(

RS274

D

),

 

then

 

data

 

format

 

of

 

Gerber

 

file

 

has

 

to

 

be

 

set

 

in

 

dialog

 

window

 

using

 

command

 

Preference

Data

 

Format

.

 

This

 

data

 

format

 

does

 

not

 

need

 

to

 

be

 

set

 

for

 

the

 

extended

 

Gerber

 

file

 

(

RS274

X

),

 

as

 

this

 

information

 

is

 

directly

 

in

 

its

 

Gerber

 

file.

 

After

 

reading

 

Gerber

 

file,

 

a

 

small

of

 

the

will

 

be

 

displayed

 

in

field

 

like

 

a

 

red

 

rectangle

 

with

 

its

equal

 

to

This

 

rectangle

 

can

 

be

 

moved

the

by

As

starts

 

to

at

 

top

 

left

 

corner

 

and

 

continues

 

to

it

to

this

to

 

the

After
