Procedures for milling and drilling
40 ProtoMat C30/C30-S
10.5 Drilling
fig. 23: Twist drill
Caution! Make sure that the board is secured in position before
drilling. Switch on the vacuum system.
The boards must be drilled with drills designed specifically for boards. It
is important that the head always lowers at a constant speed. This is
ensured by a damper built into the plotter head.
Lowering the head too quickly may result in burring, particularly with
holes of small diameter. We therefore recommend that you punch holes
with a small diameter before drilling. The
MARKINGDRILLS
phase in
BoardMaster
is intended for this purpose and uses a special universal
milling cutter, the
0.2 MM UNIVERSAL MARKING CUTTER
.
Only one board can be drilled at a time. It is not possible to stack boards
one on top of the other. A drill cover plate is not required.
All drills are 38 mm long.
See the section entitled “Practical tips” for further instructions.
10.6 Isolation milling
fig. 24: LPKF Universal (1) and
microcutters (2)
Caution! Make sure that the board is positioned securely before
milling. Switch on the vacuum system.
Ensure that the (36 mm long)
LPKF universal milling cutters
being used
are
sufficiently sharp
before you start milling. The milling width is
preset in
CircuitCAM
by selecting the isolation track width and the
appropriate tool. The preferred milling width is between 0.2 and 0.4 mm.
