7.8 Front plate engraving
fig. 42: Top: Double-edged cutter.
Bottom: LPKF Universal
Cutter
Set the traverse speed as appropriate for the engraving depth and the
material when engraving. Use an LPKF Universal Cutter or LPKF
double-edged cutter.
Caution! Switch on the vacuum system, even when engraving.
7.9 Milling solder-stop sheets
› Start up the tool library
SOLST-VS.TOL
in
BoardMaster
to load the
corresponding tools.
Create the pads in solder-stop sheets using a
MICROCUTTER
with a
tool diameter of
0.1 mm
.
The speed should be set to 40.000 rpm and the advance to 20 mm/s.
Note: Set the milling depth using an edge area of the solder-stop
sheet which is not used. Use the traverse buttons in BoardMaster
to mill a 2 x 2 mm square with the motor switched on and check the
depth.
› Once the milling depth has been set, start the milling procedure
using the file prepared by
CircuitCAM
.
› At the end of the milling procedure, check that all the pads have
been cut out. Start the milling procedure a second time if this is not
the case.
