Week4.Electronics Production

Printed Circuit Board (PCB) Manufacturing

1. Upload PNG files of the routed board, holes, and cutting frame.

2. Use mods in the tutorial/electronics production section to generate the g-code.

3. Follow the mods instructions to generate code files.

Download png file in mods. Select mill traces. and click calculate. We will use the generated file with the .ns extension in the universal g-code sender.

For the frame or holes, use the mill outline function

4. Based on the parameters in the generated file, choose a 0.3mm conical milling cutter. Loosen the nut securing the cutter, remove the cutter, and the collet if replacing with a larger diameter. To remove the collet, turn it counterclockwise. Insert the collet into the nut until it clicks, then insert the cutter to a depth of 2/3 of its total length and tighten the nut.

5. Connect the milling machine to the laptop using USB.

6. Install the Universal G-code Sender application. When installing on Windows, ensure that all folders have Latin letters, as Cyrillic is not recognized.

7. Choose the connected USB port. If ports are not found, check for USB serial drivers. After selecting the port, establish a connection.

8. Place the material on the machine's work surface.

9. Set zero by using the arrows on the controller to position it in the X and Y axes. To set the Z-axis zero, use thin paper. Lower until the cutter slightly presses the paper without it being too tight.

10. Lock the zero position with the reset zero button.

11. Afterward, start milling. There are stop and pause buttons. Pressing stop completely halts the operation and can only be resumed from the beginning. The pause button stops milling but keeps the tool spinning. Milling resumes from where it stopped.

12. The first attempt was not successful due to the uneven surface of the attached textolite. See the photo below.

13. To eliminate unevenness, mill the entire surface. However, the cutter became dull, resulting in an unsatisfactory outcome.

14. After replacing the cutter, the result was satisfactory. Since I removed it from the work surface, I had to make a new board to drill holes and cut the board along the contour. See the photo below.

It was difficult enough to solder the elements. since I have no experience soldering smd components. The result can be seen in the photo
