RELEASE NOTES - 913-0000091_rev1_v1
|
|
================================================================================
|
|
|
|
The release package contains three sets of files:
|
|
|
|
- The release notes (this document)
|
|
- A PDF of the schematic
|
|
- A bill of materials (BOM) structured in the Sierra Circuits format
|
|
- A zipped archive containing the Gerber files, drill files, and pick-and-place
|
|
coordinate files that was submitted to the fabricator.
|
|
|
|
We're fabricating this PCB with Sierra Circuits Turnkey Pro PCB service
|
|
https://www.protoexpress.com/
|
|
|
|
--------------------------------------------------------------------------------
|
|
NOTE: Because Benchmark Electronics recieves this board fully assembled, we
|
|
treat it as a PCBA in Duro. We don't have separate CPNs for the PCB and the
|
|
PCBA. When Sierra Circuits asks us for a Part Number for the PCB and
|
|
a part number for the assembly, we use the 913-0000100 CPN for both the PCB
|
|
and the assembly.
|
|
--------------------------------------------------------------------------------
|
|
|
|
--------------------------------------------------------------------------------
|
|
NOTE: This is actually revision 2 of the board, but in Duro, this is revision 1.
|
|
Benchmark expects to see 913-000090_rev1, so that's what we give it.

Here's the information to plug into the Sierra Circuits quote tool:
|
|
|
|

|
BOM Notes:
|
|
================================================================================
|
|
|
|
There are no DNI parts in this design, which makes the BOM easy.
|
|
|
|
Allow Sierra to replace caps and resistors with their preferred components.

Releasing Process
|
|
================================================================================
|
|
This project is in Altium, so we have a sligtly different release process.
|
|
|
|
- Generate the files in Altium and release them
|
|
- Use the altium web viewer to download the source files
|
|
- Rename the source files, if required
|
|
- Zip the gerbers
|
|
- Submit them to Sierra Circuits
|
|
- Copy the release files you downloaded into the github repo and push them
|
|
- In Github, create a release using those files. |
