Page 26: Materials Used For Machining
Tools and accessories 6.2 Materials used for machining In general all base materials supplied by LPKF can be used for machining. You are free to machine all other materials at your own risk. Take into consideration the notes of the manufacturers. - Page 27 FR4-material : engraving, drilling, milling Engraving film: engraving Material suitable for machining but not yet supplied by LPKF: Different HF applications: engraving, drilling, milling Danger! Keep from overheating, hazardous gases may be produced! Danger! When working with materials containing glass fibers there might be produced cancerogenous dusts.

It is important that there is no dirt (adhesive tape remains, drilling or milling chips) between the individual layers so that the base material can be laid absolutely flat. Small particles under the base material would adversely affect milling depth uniformity. ProtoMat M60... -
Page 29: The Mechanical Working Depth Limiter
Danger! Keep your fingers away from the movement area of the machine during operation! When milling isolation channels in PCB materials, it is extremely important to keep a constant milling depth.

Page 32: Isolation Milling
Caution! Before milling make sure that the PCB is positioned tightly! Switch on the vacuum system! Before milling, it must be ensured that sharp LPKF universal milling cutters (36 mm long) are used. The milling width is set to between 0.2 and 0.5 mm depending on component thickness. -
Page 33: Contour Milling In Pcb Material
After machining, the PCB has to be cleaned. This can be carried out either in a brush machine or alternatively manually with board cleaners (LPKF accessories). In either case, the PCB must be rinsed thoroughly with water to remove any copper dust produced by brushing. -
Page 34: Milling Wide Isolation Channels
The milling depth must be set such that when the copper is removed, only minimal burring results. The 3 mm double chamfered cutter is particularly well suited for milling very wide isolation channels (VDE regulations). 7.8 Front plate engraving fig. 17: Universal cutter ProtoMat M60... -
Page 35: Milling Layout Films
Use an LPKF universal milling cutter or LPKF double chamfered cutter. Danger! Use extractor when engraving, too! The LPKF ProtoMat can be used for milling through 3 mm thick aluminium front panels. 7.9 Milling layout films fig. -

Page 37: Milling Of Solder Mask Foils
If cleaning by hand, the PCB is placed on a flat support. The board is brushed in the direction of the conductor paths with wet board cleaner (e.g. LPKF board cleaner PAD). The purpose of the brushing is on the one hand to remove the layer of oxidation and on the other to remove swarf in the isolation channels. -
Page 38: Practical Tips
The solution lies in selecting the right milling direction. When isolating conductor paths with LPKF isolate, the solder side should be mirrored before isolating as the isolation algorithm itself works in a clockwise direction. The standard postprocessing is already designed for this. - Page 39 If the film is secured with elastic adhesive tape, waves may form in the film after a while. It is particularly important here that the milling base should be level (LPKF film engraving base). • Burrs are produced when milling films either because the tool is blunt or milling was too deep.
