LPKF ProtoMat 93s Manual If for some reason it should be necessary to switch the machine off and on again, then change to the Machine/Settings window of the BoardMaster program and click on OK. Thus all necessary initialization parameters like speed ranges, dwell times positions and so on are again transmitted to the machine. -
Page 15: After Switching On
LPKF ProtoMat 93s Manual During set-up take note that the bearings of the high-speed spindle have to be run in first after a longer period of standstill (several months) or after transport. During initial set-up the spindle should run at 10 000 rpm for several hours. -
Page 16: Home-Position And Two-Pin System
LPKF ProtoMat 93s Manual 3.6 HOME-Position and two-pin system The HOME position must be on the machine's X axis (two-pin system) to guarantee alignment of a double sided board. The data for the bottom side of a PCB is mirrored around the X axis and therefore the board must also be rotated around the X axis to maintain registration. -
Page 17: Programming The Home Position In Boardmaster
The home position needs to be programmed on new equipment and when the system has been moved. The HOME position of the LPKF ProtoMat 93s must be precisely on the mirror (X) axis (the two-pin system with the red plastic slides) for machining double-sided PCBs. -

Page 31: Tools And Accessories
Tools and accessories 6.1 Tools The tools for the LPKF ProtoMat 93s come in two different lengths. Tools used to machine the material surface (milling and engraving) are 30 mm long for 3 mm collets or 1.42 inch long for 1/8 inch collets, and tools used for drilling or contour milling are 32 mm long for 3 mm collets or 1.5 inch long for 1/8 inch collets. -
Page 32: Pen Holder (Optional)
LPKF ProtoMat 93s Manual Attention! Execute a tool change only in defined positions! The tools must always be inserted in the tool fixture as far as they will go. Otherwise the working depth will be incorrect. In certain circumstances, this can even result in damage to the machine base plate. -

3. Set the working depth limiter so that the ink pen just comes in contact with the paper. 6.3 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. -

LPKF ProtoMat 93s Manual Milling and drilling with the LPKF ProtoMat 93s 7.1 Securing the PCB on the machine bed Make 3.0 mm alignment holes in the base material and backing material spaced the same distance as the alignment pins. This can also be done with any upright drilling machine. -
Page 35: The Mechanical Working Depth Limiter
Attention! 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. With the LPKF ProtoMat 93s, this done by the mechanical working depth limiter. - Page 36 2. The material is held down within certain limits by the working depth limiter.

Page 39: Drilling
Attention! Before milling make sure that the PCB is positioned tightly! Switch on the vacuum system! Before milling, it must be ensured that sufficiently sharp LPKF universal milling cutters (30 mm long or 1.42 inches long) are used. The milling width is set to between 0.2 and 0.5 mm or 0.008 and 0.020 inches depending on component... - Page 40 (<0.2 mm isolation) is used, the tool wears more quickly than with deeper drilling. The LPKF micro-cutters can be used to produce even smaller isolation channels, but their service life is about 10% less than that of the above-mentioned universal cutters.
-
Page 41: Contour Milling In Pcb Material
(2mm/sec. or 0.1 inch/sec). The 2 mm contour milling cutter is substantially more robust, but does not remove as much material as the 3 mm milling cutter. Many LPKF software postprocessors are calculated for the 2 mm milling cutter (e.g. CUTTING). -
Page 42: Milling Wide Isolation Channels
For engraving, set the speed of movement as appropriate for the engraving depth and the material. Use an LPKF universal milling cutter or LPKF double chamfered cutter. Attention! Use extractor when engraving, too! Aluminum front panels can be milled through with the LPKF ProtoMat 93s circuit board plotter. -
Page 43: Milling Layout Films
LPKF ProtoMat 93s Manual 7.9 Milling layout films Secure the film base (sheet of perspex or glass) on the machine table with masking tape. Lay the film material on the base with the coated (matte) side facing upwards. Now smooth the film material firmly and level on the film support until the air has been completely expelled. -
Page 44: Coloring Milled Films
LPKF ProtoMat 93s Manual 7.9.2 Coloring milled films For milled negative films, there is Duroscal Einfärber schwarz, with which positives can be made. The fully milled gravure film is colored with Duroscal Einfärber by pouring the liquid onto a SAFIR pad and spreading it evenly over the whole film. -
Page 45: Basis Material
Special base materials with a thicker copper layer of up to 300 µm can no longer be machined with the LPKF universal milling cutter. Contour milling cutters or special tools are needed for this. In these cases, we would ask that you consult us and send sample material so that tests can be carried out if appropriate. -
Page 46: Cleaning The Pcb
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 47: 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 48 LPKF ProtoMat 93s Manual • Drill deflection occurs in particular with thin tools which are no longer absolutely sharp. However, this also depends on the surface structure of the material. If, for example the glass fiber structure of FR4 materials penetrates the copper, drill deflection cannot be avoided even with a sharp tool.
