PCB automatic board making machine operation guide
When you buy a PCB circuit board rapid production machine, you naturally want to make a circuit board immediately to see its powerful functions, but please don’t be in a hurry, and please read the instructions and the operation introduction in this column carefully before you start. You will soon become familiar with the operation and will be deeply attracted by its charm.
1 Please check whether your accessories are complete
Instructions, fastening tools, DK engraving driver CD, tools, drills, serial port extension cables, power cables, a small amount of copper clad boards, spindle motor carbon brushes.
2 Place the machine flat on the work platform
Take out the serial port extension cable (DB9 cable), connect the communication interface on the right side of the chassis to the computer COM1 port, and connect the power cord.
3 Please confirm that your computer operating system is win98/2000/XP,
The minimum memory configuration is 256M, turn on the computer and insert the DK engraving driver CD, and run the corresponding setup.exe file. Open a PCB file in PROTEL and import it into DK.
4.You can choose the appropriate tool according to the circuit board design.
For the tool selection parameters of the DK operation interface, it is recommended to choose a safety distance slightly smaller than the safety distance in the PROTEL PCB file design (for example, if you choose a 0.38mm tool, the tool parameter should be 0.36mm). You must check whether there is any circuit board line adhesion caused by the wrong tool selection after opening the file until the correct one is selected. Set the “board thickness” parameter of the DK operation according to the thickness of the circuit board. This operation provides accurate data for drilling and cutting edges.
5.Because the operating system will work slightly below the bottom of the circuit board when cutting edges and drilling.
In order to protect the tool, drill bit and machine working platform, the working platform must be equipped with a copper clad board that is equivalent to or slightly larger than the circuit board to be made as a pad, and then place the copper clad board you want to make; note that it is ideal to place the copper clad board with thin double-sided tape. When pasting the copper clad board, the pasting surface must be free of particles. Press it flat by hand to ensure that the copper board is placed flat. The copper board used is also required to be flat to ensure the quality of the engraved circuit board. It is recommended to use the original copper clad board that has been polished and flattened provided by our company. When installing the copper plate, remember to pay attention to the tip of the tool installed on the spindle motor. If necessary, install the copper plate and then install the tip of the tool for safety.
6 After the copper plate and tool are installed
Move the spindle and the work platform without turning on the main power of the machine, so that the tip of the tool is near the lower right corner of the copper plate. After confirming that the spindle power is off, turn on the main power. At this time, the online light is green. Press the online key to turn the online light red, indicating that the machine is offline; adjust the X and Y axis positions, and then adjust the Z axis height to make the tip of the tool close to the copper plate. Use the Z+1mm key to roughly adjust to the visual distance close to the copper plate. Put a piece of waste paper (it is recommended to use white paper torn off with double-sided tape) on the circuit board, and use Z+0.1mm to gradually adjust it, and finally use Z+ 0.01mm to adjust it until the tip of the tool just presses the paper.
7 Close the machine door, press the online key to turn the online light green, and turn on the spindle power.
If the PCB file tool and board thickness parameters have been set, you can press the trial engraving key, the cutter head starts to move, and engrave a rectangle according to the maximum area of the designed circuit board. Observe whether the engraving depth meets the requirements. If it is too deep or too shallow, press the online key to make it offline. Press the Z-axis adjustment button to adjust the height, then press the online key to make it online, and then press the trial engraving until the engraving depth meets the requirements, and then press the engraving key to engrave. After the engraving is completed, the spindle continues to rotate, but stops at the lower right corner of the circuit board and does not move. At this time, press the trimming key, and the machine starts to cut the shape according to your design. After the cutting process is completed, turn off the spindle power. Do not turn off the main power at this time. Press the online key to turn the online light red, press the Z-axis adjustment key to raise the Z axis, take out the flat-bottomed sharp knife, replace the drill bit, adjust the Z axis so that the drill bit presses the white paper, press the online key to turn the online light green, close the machine door, turn on the spindle power, press the drilling key to start drilling, and turn off the main power and spindle power after completing all operations.
8 Usage tips and precautions:
8.1 Develop a good habit and make sure the spindle power is off before turning on the main power. When turning off the main power, turn off the spindle power at the same time.
8.2 Install the tool and drill and tighten the fixing screws.
8.3 The green online light indicates that the computer and the machine are online, and the red light indicates that the machine is offline. In the online state, the X, Y, and Z axis movement buttons are not controlled, which is not a fault.
8.4 If the cutter head is found to be too deep or too shallow in the working state, you can press the online key to turn the online light red. The spindle continues to rotate but does not move. At this time, you can adjust the spindle height and continue to work online.
8.5 When the power is turned on, all the lights on the entire control panel flash. This means that the machine has not been reset successfully. Please turn off the main power and spindle power, and then turn them on again after one or two seconds. If the main power is suddenly turned off during the working process and then turned on again, the machine will not be completely reset, which will cause the machine to work randomly. Do not try it randomly.
8.6 When opening a file, it prompts “non-PCB file”. This machine is compatible with PROTEL ASIC2.8 file format. If your drawing software cannot output this format, please import the file you designed in PROTEL99 and export it in this format after conversion.
8.7 When opening a file, it prompts “no KEEPOUT LAYER”. This machine uses the forbidden wiring layer as the outer frame of the circuit board. The PCB file you designed must draw a border line on the KEEPOUT LAYER, and the line width is equal to the tool diameter (3.15mm).
8.8 It displays “out of engraving range”. There are components or lines outside or close to the KEEPOUT LAYER. Please modify the circuit diagram.
8.9 The machine does not respond when pressing the function key. Please check whether the serial port line is connected correctly: check whether the online light is green.
