Procedures for milling and drilling
42 ProtoMat C30/C30-S
Danger! All speeds and feed rates prescribed in
BoardMaster
are
for FR4 material. You should begin at a lower feed rate when
working with other materials. Please note that some materials,
including FR4, may produce carcinogenic dusts (from glass fibres).
You should therefore always work with the vacuum system
switched on. Always use a microfilter. Some materials (such as
Teflon) may produce lethal gases during cutting.
10.8 Milling wide isolation channels and rubouts
fig. 27: Double-chamfered cutter
Wide isolation channels and rubout areas (the removal of areas of
residual copper) can be created using 36 mm long double-chamfered
cutters.
Various diameters (0.8 mm, 1 mm, 2 mm, 3 mm) are available
depending on the size of the area of copper residue to be removed.
The milling depth must be set such that the copper is removed with
minimal burring. The 3 mm double-chamfered cutter is particularly well
suited to milling very wide isolation channels (VDE regulations).
10.9 Front plate engraving
fig. 28: Top: Double-chamfered
cutter. Bottom: LPKF
universal milling cutter
Set the traverse speed as appropriate for the engraving depth and the
material when engraving. Use an LPKF universal milling cutter or LPKF
double chamfered cutter.
Danger! Switch on the vacuum system, even when engraving.
