6.4 Drilling
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 setting may be made with two setting nuts in
the pneumatic block on 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

phase in BoardMaster is intended for this purpose and uses a special
universal milling cutter, the "

.
Only one PCB can be drilled at a time. It is not possible to stack PCBs one on top of the
other. No drill cover plate is needed.
All drills are 38 mm long.
See the section entitled “Practical tips” for further instructions.
6.5 Isolation milling
LPKF Universal (1), Micro (2) and RF cutters (3)
Caution
Check that the board is properly secured before milling.
Switch on the vacuum system.
Ensure that the (36 mm long) LPKF Universal 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.
It is recommended that you degrease the board material with a cleaning spray (degreaser for
electronic components). This makes it easier to suction off the millings.
