Milling the PCB
Let's make first Fab ISP Module
We are going to use Roland MDX-20
Well, I usually use CNC Machine (Shopbot) to milling the PCB, but in this assignment, I will try for the first time to use Roland MDX-20. Be patient and let's learn how to make ISP (Milling BCP).
Since I did the previous assignments using Windows I thought it will be easy to do Electronic Production assignment by using Windows. But, before I start to do the assignment I prefer to go back to the tutorial and read several previous works I decided to use ubuntu 16.04.
First of all, you have to install Fab Module in your system and to do that you just need to follow a good tutorial showed you the steps clearly. Here is the great tutorial to be able to use the MDX-20. Once you finish installing the Fab Module will be able to use Fabmodules web interface.
Remember you have log in as a root
It's a good tutorial to instal Fab Module MDX-20
I had an issue to assigning the serial port, and to solve this problem I did install the backends for Python and I get access to control the MDX-20

Starting Milling the BCP
Once you finsh installing the Fab Module MDX-20 will be able to open the web page of Fab Modules
The Instruction to Trace the ISB
- Select the image(.png) for the ISP Trace layout as png
- Roland mill (.rml)
- PCB traces (1/64)
- In the output machine choose the MDX-20
- Write down your xyz 0 axis
Cut Depth = 0.6 mm
Calculate and send to machine
After trace the layout for the ISP
The Instruction to cut the ISB
the cut depth = 0.85 mm
The stock thickness = 2.3 mm
Calculate and send to machine
After trace the layout for the ISP

Soldering the ISP
Using SMD Components
The Electronics Components that used for the module:
- 1x Attiny 45
- 2x 499 ohms
- 2x 49.9 ohms
- 2x 1K ohms
- 2x 3.3V Zener Dioed
- 1x 2x3 in header
- 1x 100 nf capacitor
- 1x Red LED
- 1x Green LED
I had never solder SMD components before and this was first try
Second Try
First successful soldering
Perfect soldering ISP I have been done until this moment
