CAD files

Spectrometer chip package CAD files and documentation

This documentation is intended for PCB layout and opto-mechanical alignment.

Chromation does not provide design and manufacturing files for the internal design of the spectrometer chip itself.

Chip package render

The chip package should look like this after importing into 3D CAD software:

            └── CUVV-45-1-1-1-SMT v1.step

The chip package is designed in Fusion360.

• if you use Fusion360, import the .f3d file
• if you use different 3D CAD software, import the .step file
• if you do not have 3D CAD software, you can still view the part and measure features using this link

See hardware/design/CUVV-45-1-1-1-SMT/CUVV-45-1-1-1-SMT_technical-note-1.0.pdf for additional information about the spectrometer chip.

The PCBs (printed circuit boards) are designed in EAGLE.

The EAGLE files are in the hardware/design folder. The following files are available now, additional design files are coming soon.

• if you have EAGLE, simply open the project (this reads the .epf file to determine which files to open)
• if you do not have EAGLE but are able to import EAGLE files:
  • the schematic is the .sch
  • the board is the .brd
  • the BOM-and-pick-and-place is the -xyrs-bom.csv
  • the library components for all three boards are the .lbr files in the hardware/design/lbr folder
• if you do not have EAGLE and are unable to import EAGLE files:
  • PDFs of the circuit schematics are in hardware/design/pdf
• hardware-design.md is electronics design calculations and related documentation
  • vis-analog-out hardware-design.md
  • vis-spi-out hardware-design.md
  • usb-bridge hardware-design.md

• The manufacturing files (Gerbers and Drill) are in the hardware/manufacture folder.

• view the Gerbers with a Gerber viewer such as gerbv
• the PCBs are 4-layer
• gerbv screenshots of each layer-view (top/bottom/inner1/inner2) are in hardware/manufacture/img
