Manual ProtoMat 95s/II 2.11 What is LPKF BoardMaster used for? The data required to drive the plotters is generated by postprocessing with LPKF CircuitCAM and is stored in an LPKF binary file (LMD format). BoardMaster now reads these files, decodes the plotter commands and modifies them for the particular machine being driven. This is necessary as although different machines may perform similar operations, they nevertheless use different command sets.
ProtoMat 95s/II Manual 17 3 Setup 3.1 Before switching on Caution You must ensure that the voltage set on the machine corresponds with the mains line voltage before switching on. If not, see the section headed Setting the device voltage, electrical fuses. Remove all objects from the plotter and its traverse range before switching on. Pilot pins must not be projecting from the board material. Caution Carefully close the hood. Never reach into the machine while it is running.
ProtoMat 95s/II Manual If, for whatever reason, it should be necessary to switch the machine off and back on, you must switch briefly to the BoardMaster Machine Settings... dialogue box and quit this with OK.

ProtoMat 95s/II Manual 3.6 Functional test using LPKF BoardMaster Caution Make sure that no other persons are working on the machine while the first functional test is taking place. First check the configuration of the serial port: 9600 baud , 8 data bits, 1 stop bit, no parity bit, hardware handshake and FIFO off. Also check that the correct interface has been selected in BoardMaster under CONFIGURATION, CONNECT... . Consult the BoardMaster manual if you require assistance.
ProtoMat 95s/II Manual 25 3.7 HOME position and registration hole system The HOME position must be on the machine's axis of symmetry (registration hole system) to ensure correct alignment of a double-sided board. Double-sided boards are rotated about this axis of symmetry. Inaccuracies in the HOME position result in misalignment when double-sided boards are rotated during the machining process. The HOME position is contained on the configuration diskette supplied as standard.
ProtoMat 95s/II Manual 3.8 Checking and correcting the HOME position The test file NULL-PKT.LMD is supplied with the installation program to simplify the procedure for checking the HOME position. This program drills a hole on one side of the board and then rotates the board before milling a circle in the same place. This allows you to perform a visual check on the position of the HOME point on both axes. Carry out the following steps: 1. Make registration holes in double-sided board material. 2.

ProtoMat 95s/II Manual 41 5 Tools, material and accessories 5.1 Tools Tools for the LPKF ProtoMat 95s/II have a diameter of 1/8 inch and two different lengths. Tools used to machine the material surface (milling and engraving) are 36 mm long while tools used for drilling or contour milling are 38 mm long. The following tools are available. 1 2 3 4 5 6 LPKF tools for circuit board plotter 1. 36 mm long LPKF Universal LPKF cutter for milling isolation channels and for engraving front plates from 0.
ProtoMat 95s/II Manual 5.2 Materials used for machining In general all board 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.
ProtoMat 95s/II 6 Manual 43 Stages in milling and drilling 6.1 Securing the PCB on the machine bed Make 3.0 mm or 3.05 mm diameter congruent registration holes in the board material and drilling base in the x-axis. This can also be done with any bench drill. Please note that the diameter decreases during galvanic through-hole plating. Tip: The drilling base should be drilled to a larger diameter, such as 5 mm, to allow for inaccuracies in the registration holes.
ProtoMat 95s/II Manual 6.2 The mechanical working depth limiter Caution Keep your fingers clear of the machine's traverse range during operation. It is particularly important that you keep the milling depth constant when milling isolation channels in board materials which tend are often slightly curved. This is achieved by the pneumatic working depth limiter on the LPKF ProtoMat 95s/II. This provides the following benefits: 1.

ProtoMat 95s/II Manual 47 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.
ProtoMat 95s/II Manual The milling depth must be set as large (deep) as possible in all cases. If only the extreme milling cutter tip (<0.2 mm isolation) is used, the tool wears more quickly than with deeper drilling.The LPKF Micro Cutters can be used to create even finer isolation channels but their service life will be only approximately 20% of that of the LPKF Universal cutters mentioned above. Caution: Do not confuse Micro Cutters and Universal Cutters.
ProtoMat 95s/II Manual 49 6.7 Milling wide isolation channels and rubouts Double-edged cutter (end-mill) Wide isolation channels and rubout areas (the removal of areas of residual copper) can be created using 36 mm long double-edged cutters. Various diameters are available (0.8 mm, 1 mm, 2 mm, 3 mm) depending on the size of the residual copper area to be removed. The milling depth must be set such that only minimal burring results when the copper is removed.
ProtoMat 95s/II Manual 6.10 Milling layout films LPKF RF Cutter • Layout films may be machined with LPKF RF Cutters. • Secure the film base (plexiglas or glass sheet) onto the machine bench with Tesa tape. • Lay the film material on the base with the coated (matte) side facing upwards. • Now flatten the film material out firmly on the film support, expelling any air completely. • Now stick down the film on all four sides with a non-stretching transparent adhesive tape to form an air seal.
ProtoMat 95s/II Manual 51 6.10.2 Removing the coating When removing coatings, only treat one film per container to prevent any damage of the second film by contact between the back of it and a surface wet with colour. Caution Follow the safety instructions on the quick-acting coating remover container. There are two options for coating removal: 1. Quick coating removal.
Manual ProtoMat 95s/II 6.11 Tool libraries in BoardMaster BoardMaster can be loaded with a previously created library of various tools as an aid to deciding which tool can be used for which materials. Select the MILL/DRILL submenu of the CONFIGURATION, TOOL LIBRARY menu in BoardMaster. The MILL/DRILL TOOL EDIT dialogue box opens and you can now LOAD a suitable tool library from the directory selected. The tool library directory is called c:\lpkf30\bmaster. Tool libraries have the extension .
ProtoMat 95s/II Manual 53 6.12 Board material In principle, all board materials can be machined although the LPKF ProtoMat 95s/II is not intended for machining wood. However, phenol resins of lesser quality, such as FR 2, can adversely affect the milling quality. Glass fibre reinforced epoxy material (FR 4 or G 10) can be a health hazard due to the milling dust produced (allergies, risk of cancer). Tool service life is also substantially reduced. Caution Never work without the extractor running.
ProtoMat 95s/II Manual 6.13 Cleaning the PCB Before components are mounted, the finished PCB must be thoroughly cleaned. This can be done manually or in a board brushing machine. If cleaning by hand, the PCB is placed on a flat support. Brush the board with a wet board cleaner (such as the LPKF PAD board cleaner) in the preferred direction of the conductor paths.
ProtoMat 95s/II Manual 55 6.14 Tutorial on creating a printed circuit board It is assumed that the relevant milling data has already been loaded or prepared in BoardMaster. For example, the data from the CircuitCAM tutorial can be used. A further requirement is that the HOME position has been programmed exactly as described above. A tool list must be defined and the tool magazine must be filled according to this list. Caution Take care when handling the tools. Danger of cutting.
ProtoMat 95s/II Manual 16. Once the holes of the current diameter have been drilled, the next tool is fitted in the same way. 17. When the drilling phase has finished, the MILLINGBOTTOM milling phase is selected once any galvanic through-hole plating has been carried out. 18. The milling depth should now be set. To do this, click on Universal Cutter 0.2 mm in the Tools combo box (top left in the screen). 19. The plotter head travels to the zero position.
ProtoMat 95s/II Manual 57 6.15 Practical tips • Set the milling depth such that engraving is too deep rather than too shallow. Insufficient depth when engraving increases wear on the milling tool. • There are a number of reasons why the milling width (depth) might be uneven. It is important that the machine bed is truly clean. Adhesive tape residue and such like can have a significant adverse affect on the milling depth. Millings between the machine bed, drilling base and board reduce precision.
ProtoMat 95s/II Manual Tip: • We recommend that you punch-mark small diameter holes before drilling. The MARKINGDRILLS phase in BoardMaster is intended for this purpose and uses a special universal milling cutter, the " UNIVERSAL CUTTER 0,2MM FOR MARKING". Vitrification of the drilled hole occurs as a result of the board material melting when the drill remains in the hole too long after the hole has been made. These holes then cause problems for through-hole plating.
ProtoMat 95s/II Manual 59 7 Appendix 7.1 Maintenance Keep spindles clean. In rooms with a high air humidity, wipe down with a lightly oiled cloth from time to time. Keep transport spindles oiled and clean. Do not oil the bearings. 7.1.1 Working depth limiter Dismantle and clean the working depth limiter at regular intervals. To do this, first switch off the machine. Then proceed as follows: 1 1. Undo the pneumatic connection.(1) 2. Remove the plug from the spindle (3). 3.
