Paul is correct with regards to the PCB Fabrication. When it comes to Assembly:
- Programming the Pick & Place machines to populate the boards.
- Programming Optical Visual Inspection machines for Quality Control
- Programming of Selective/Wave machine (if applicable)...
basically any sort of programming/preparation required to get the line ready to assemble and quality control the build.
Setup: unlike NRE which is generally a one time charge unless new revisions have significant or modifications that affect the production greatly, Setup is usually charged on every build, and it basically:
- Setting up the machines
- loading components onto feeders
Tooling is purely a PCB Fabrication charge and is not really relevant to Assembly.
