Power Management Unit – Build Part 2
In part two of our Power Management Unit Build we are going to start constructing the front and back panels of the case.
To start I apply painters tape to the front and back panel in a semi successful attempt to prevent marring of the panels.
Then I use product spec sheets and a caliper to layout the component placement on the panels.
Finally I use a drill press, air hack saw and a Dremel tool to cut out and finish the panels.
In working on the panels I learned a couple of things.
1. I need to be more precise when cutting out holes with the air hack saw. I spent a lot of time with the Dremel tool making the cutouts larger.
2. I will probably need to put two layers of painters tape on the panels. The air hack saw bounced around a lot and marred the panels.
3. When drilling the holes, I need to stop and remove the shavings as I go along. In some areas, the shavings scratched the panels as they turned on the drill bit.
I would really appreciate it if anyone has any suggestions on how to do a more professional job on this process. It looks ok, but I would like to have a cleaner more finished look as I move forward.
In part 3 we will mount some of the boards and install the components in the front and back panels. I also still need to cut holes in the back panel for the Arduino USB connection and the Ethernet port.
