== Fall 2009, Current Progress ==
We now have one fully working prototype of the SiPM Digital Control Board, and the SiPM Amplifier Board is currently being manufactured and assembled by Sierra Circuits, Inc. The backplane design is nearly complete and will be going out for quoting within a week.
Here is a zip file containing the most recent versions of the tagger files: [http://zeus.phys.uconn.edu/~underwood/TaggerDocs/TaggerMicroscopeProgress20091112.zip Design Snapshot 11/12/2009]
A few notes about these files:
*There are four subfolders in the zip file. The folders for the three PCBs are clearly labelled. Each PCB folder has one project file (.PrjPcb) which can be opened in Altium Designer. Each project file refers to only one PcbDoc file, making it easy to figure out what you should look at to see the board.
**The SiPM digital control board project has 4 shelved polygons which should be restored (Tools->Polygon Pours->Restore 4 shelved polyons) to see the state of the board as it was last manufactured. Revisions from the testing process have not yet been entered into Altium but can be reviewed on this wiki.
**The SiPM amplifier (analog) board project will give an error message that it was unable to find "Test PCB.PcbDoc". Please ignore this. The file was intentionally omitted to prevent confusion, and is not related to the actual design.
**The backplane project will give an error message that it was unable to find "Backplane_New.PcbDoc". Please ignore this. The file was intentionally omitted to prevent confusion, and is not related to the actual design.
