You are a supplier of printed circuit boards (PCBs). Production of the circuit boards consists of several steps – Surface Mounting, Baking, and Final Assembly. Surface Mounting puts integrated circuits (ICs) and other components on a PCB. These PCBs are then Baked as a batch and kept in an oven for some time so that the ICs are soldered onto the PCBs. Finally, these PCBs are taken and manually assembled into a case, and wired with connectors. The processing rate at the Surface Mounting station is 15 PCBs/minute, the processing rate for Baking is 5 PCBs/minute, and the processing rate for Final Assembly is 3 PCBs/minute. If there are on average 24 units of (work in process) inventory and the system is working at capacity, what is the flow (throughput) time for PCBs?

Work In Progress units = 24
Processing rate for surface mounting station = 15 PCB/min
Processing rate for baking station = 5 PCB/min
Processing rate for final assembly station = 3 PCB/min
