Description: SMT Hand Placement is the process of having a worker install Surface Mount (SMT) components on the surface of the PCB manually. (See also: SMT Auto Placement). Machine selection provides the choice of three options: Unskilled, average, and highly skilled labor, differing in the number of parts per hour they can place. Default = “average”.
Major Cost Drivers -- PCBA SMT Hand Placement
SMT Hand Placement cycle time is mainly determined by Hand Placement Deposition Rate.
Process Time = Device Placement Time
- Device Placement Time = Quantity SM Hand Placed Components/Hand Placement Deposition Rate
- Hand Placement Deposition Rate = (Machine variable) /SEC_PER_HR
- // Throughput calculations for units per hour through this process.
- Process Throughput = Process Capacity/(Cycle Time/SEC_PER_HR)
- Process Capacity =(Machine Variable)
