Electronics Production (PCB Milling and soldering)
This week’s Assignment is to make the FAB ISP (ICSP) Using a milling machine to mill the PCB and also soldering the SMD components to the circuit and programing it I wanted to something really awesome but in true A-TECH fashion I built the basic model because it better to have a working base model then go fancy
Project: FAB ISP (ICSP)
Goal: TO Mill, solder and program a fab isp (ICSP)
To start of i needed to download the trace file and the cutout file for milling
Now using a bit of double sided tape fix your pcb stock to the milling machine bed
And after a bit of fab modules work (In Ubuntu):
-
Open the terminal (Ctrl+Alt+t)
-
Type "Sudo fab", and your computer password
-
Choose your input format "image (PNG)" and your output format "Modela (RML)"
-
Now load your file and set you milling profile to "Mill traces 1/64"
-
Set your origin to the lower left corner of the pcb stock
-
Hit make path >>then>> Make rml >>then>> send it >>then>> Begin Milling
-
And after it finish milling the traces repeat steps 4-6 but with the interior file
The machine was up and running milling the board
After a bit of cleaning
And now wielding the soldering wand
And after a bit of soldering
we have
a working fabisp
and after downloading the firmware and running it in Windows (success)
I desolder the 0 ohm resistor and break the solder joint
now we can use the programmer
