So there are some other questions similar to this, but none of them talk about how to designate the placement of components for the manufacturer.
I use a pretty uncommon piece of software for designing my PCBs (sprint layout), so I can't just send the project file because they won't be able to open it.
I have done PCB manufacture before without assembly. All I have to do is send the company the gerber and drill files.
Now to do a pick and place, I also have to provide a BOM; this I understand.
What I don't understand is how they program the machine to place the components at the right location. Do I need another file for this? Is it good enough to just have the component numbers on the silkscreen layer and have them figure it out themselves, or is there some type of other file I have to include to tell them the exact location to place the components?

what they need is either:
A. Reference designators and a pin 1 marker on the relevent chips, markings for diode orientation, polarity markers for caps, etc on the silk scren
B. A fabrication layer with all that information
In both cases, you will have supplied a BOM which will generally make clear what the chip markings are, but in doubt, put it on a fabrication layer.
