We sometimes get asked how to prepare a design for manufacture on a pick and place machine. There are things to be aware of that are not needed for your prototype, including fiducials, which are marks on the board that help the machine’s vision system place the components accurately. Also the way that components are provided makes a lot of difference to how long it takes to set up the run.
An excellent introduction to design for manufacture is provided by Dave Jones. We strongly recommend watching it before sending your design to be made. Having said that, we can handle 0402 sized components, but are happy to use other sizes if required.
