I was working @ a downhole tool company. I worked with 2 technologists responsible for the pick and place machine, PCB loading and unloading as well as assembly of prototype test PCBs. This was a company of ~15 engineers, 1 mathematician, 5 technologists in total, several machinists cutting Hastelloy and me a technician doing QA/QC as well as repair service. We managed to pay for a pick and place machine in ~3-4 months is what I heard and that was including operating a business profiting to the extend that there was a ~USD $7,000,000.00+ in the bank account for the rainy day fund. We barely kept the pick'n place machine busy but it was a major benefit for the operation that saved money. A used one is not that much if one looks about. A small consistent operation can afford a pick'n place machine if they are organized and efficient. It's not rocket science and they are not millions of dollars for a small operation easily stuffing several-hundreds+ of PCBs per month. It enabled the business to do things not possible without a pick'n place machine.
