There exist different numbers.
IPC9850 tryes to standarize this numbers, and there exist IPC CPH and vendor CPH.
If you have only vendor CPH, lower that by 30% in order to estimate IPC CPH.
As example if machine have 15kcph for resistors (laser centering) where the machine pick up
6 resistors at the same time and place it near at same time, the IPC cph is 9kcph and for vision,
it is 4,5kchp and fine pitch vision 1.8kcph.
Real mixed cph is for determinated circuit and feeder loading is 7.5cph. The pcb have 48 components and the panel is compromised of 6x2 matrix.
This are 576 components and 276 seconds for assembling, For the 26 Fiducials, each needing 0.6 seconds, is 15.6 seconds, and for panel unloading/loading, 22 seconds is needed.
This is gives tact time of 336 seconds and approx 6.2kcph.
Instead just as example, if the pcb is not panelized, the tact time is 70 seconds resulting at 2.5kcph performace.
