Does anyone know a formula for determining my "Excess Capacity"? I know my machine's up AND down time, the effective placement rate, and my idle time. If my manager asks me what out "excess capacity" is, how do I use my "knowns" and calculate an ac

I am task to make productivity improvement for production. The line configuration is as follow: MPM Printer/S20/S20/S20/S20/GSM/GSM/MVT/BTU How to calculate the capacity of the above configuration? What factors do I need to consider?

Get a stopwatch & time your functions to see which is the slowest. I am guessing it's going to be the oven, printer (if using paste inspection) or the AOI. If you are talking the average or optimum speed in CPH, that would depend on the type of b

Not sure what's in your line equipment wise, but you need to know relatively what kind of placements per day you run regardless of the mix. We run around 1.1 million across 5 lines in 3 shift. Calculate what kind of placement per day on a specific

Thanks for the input. I am reading IPC9850 and have a question on its statement. ========================================================== 4.2.9 Preventative Maintenance (PM) Time ... Calculation Method: Multiply the amount of time required for ea

Thank you very much for your reply. I do have the numbers for placement per hour, but, I have some concerns on it (forgive me if it is a stupid concern, as I said, I am new in this field, and trying to figure out this business). For example, it is

I am interested in seeing how some of you calculate machine utilisation. Currently this was calculated off against the uptime. I really believe there is a better way of doing it i.e if I were to calculate this against machine's capacities. Any feedba

If you define cycle time as the time it takes to complete one board it is a useless number. What you need to know is the time it takes to complete one board and start the next board. This means first fiducial on first board to first fiducial on th

I can't comment on the firm, but the approach is a good starting point for calculating your Kanbans is with capacity lot sizing http://www.synchronousmanagement.com/cls.html
