Getting Ready For PCB Manufacture And Assembly

One-off Costs

These are sometimes called tooling costs. There is no charge for these if the same PCB design is made again in the future.

For a manufacturer, these costs include:

  • Loading the design files into their system
  • Checking the PCB for any manufacturing problems and adjusting as neccessary (e.g. removing soldermask slivers)

For an assembler, these costs include:

  • Loading the design files into their system. This is normally substantially higher than the similar manufacturing costs, as they have to load all of the components into their system
  • Sourcing all of the required components (this may also fall under re-occurring costs)
  • Manufacturing a soldermask stencil (typically laser cut from stainless steel)
  • I believe this is called “one-off”, not “one-of”.

    • Thanks for bringing this to my attention. Easy fix 🙂
