Electronics Production

Electronics Production


Task: This week's assignment is related to producing printed circuit boards.
In particular we were asked to mill and program the FabISP board, which allows to program new AVR microcontrollers .


It was my first time to make a PCB board , I have poor knowledge about the electronics production
And I`m really excited because in this week I will learn something new.



PCB (Printed Circuit Board) an electronic circuit consisting of thin strips of a conducting material such as copper, which have been etched from
a layer fixed to a flat insu++++++++++++++lating sheet called a printed circuit board, and to which integrated circuits and other components are attached.


Milling the board

In our lab we have Roland SRM-20 milling machine, I will use this machine for PCB production



After downloading 2 .PNG files from the already existing design, one is the outline that is the cut out frame
and the other file represents the traces which are inside cut.

I generated the file using Fab Modules software this program converts the - PNG file- to .Gcode for Roland machine.

I used Fabmodules to create the required (tool path) code for the milling machines.
1/64 size drill bits selected for milling the traces and 1/32 for cutting the PCB respectively.


First step in Fab Modules software is to upload the png file . then chose the output form Roland mill (.rml)




For milling we chose 1/64 PCB traces process.




I chose the following settings:





To make sure that the setting is right we chose to calculate the file :


The problem was that the toolpath wasn't connectedwith some traces.

For solving this problem I re-uploaded a new PNG file and Made a previous setting for the first file.





Then calculate the tool path with parameters :





For milling the boundary I select the png file then set the value, for cut we decrease the speed to be 0.5 mm/s which as a result took more time to cut

we chose 1/32 PCB outline.







Now! My png file converted to G-code so I can start miling using Roland SRM 20 software interface to complete the process.



The important things which I learned from my experiences is to compensate effects of uneven bed surface, it's better to set z-axis zero just under the surface.
I used the multimeter to check if there is conductivity between the Z-axis and the sheet.




For cut the boundary we have to change the drill tool we chose 1/32 drill pit size.




This is how the final result of both cuts looks:



Soldering the componets


It was my first experience in soldering, so it tooke a long time and needed much trial and error.
The components that I used are:




Programming

The software wich I am using is ARDUINO
we use Arduino UNO to help fabISP to act as an ISP, we chose from example Arduino ISP
First, I connect the Arduino board to the USB hub, press on File .. Example select Arduino as ISP



Upload the code




Then I plugged the the arduino with the USB by a cable, checked that the arduino is connected, then I checked the type of arduino.


The upload is finished and the arduino became a programer.



Now it is the time to use Ubuntu, we install the AVR Programming and follow the steps :

Open Terminal and type:
These commands are for the computer to install the suitable drivers:

- sudo apt-get install flex byacc bison gcc libusb-dev avrdude
- sudo apt-get install gcc-avr
 then "y" when asked to do so by your system
- sudo apt-get install avr-libc
- sudo apt-get install libc6-de

for downloading the firmware in a convenient location in my computer and unzipping it:

cd ~/Desktop

wget http://academy.cba.mit.edu/classes/embedded_programming/firmware.zip

unzip firmware.zip


Then I connect the Arduino and my PCB with wires by following this picture.






After I connected it with arduino, I used terminal to write this commands:

-sudo make clean
 (it will delete the executable file and all the object files from the directory)

-sudo make hex
 (it will create new files that are up to date and the base for new program files suitable for the system)


Then I opened the MakeFile and commented this line AVRDUDE = avrdude -c avrisp2 -P usb -p $(DEVICE) by adding a hashtag "#"
and instead I typed AVRDUDE = avrdude -c stk500v1 -P /dev/ttyACM0 -b19200 -p $(DEVICE)


Now to Join the executable files with the Makefile we type :
sudo make fuse
to Compile the program :
sudo make program
This compiles the program.


my terminal log.
