Electronics production
This page documents the group assignment for week 08 of Högni, Jóhannes and Ólöf.
Group assignment:
- [] Characterize the design rules for your in-house PCB production process: document feeds, speeds, plunge rate, depth of cut (traces and outline) and tooling.
- [] Document the workflow for sending a PCB to a boardhouse
- [] Document your work to the group work page and reflect on your individual page what you learned
Overview and approach
We did the group assignments in two different locations.
Ólöf worked with the Shopbot at Fab Lab Austurland.
Högni and Jóhannes worked with the Roland milling machine at Fab Lab Ísafjörður.
Characterizing our in-house PCB production
We used this linetest to characterize our in-house PCB production. When performing this test we begin by doing the traces with a 1/64" endmill and we only remove the top layer of copper from the board. Then we do the interior with a 1/32" endmill and cut the outline. The cut goes all the way through, separating the PCB board from the plate.

The MonoFab SRM-20
We have a MonoFab SRM-20 milling machine in our Fab Lab Austurland. It is usually used for milling PCB boards but according to this site it can mill all kinds of things.
