And don't forget to implement the "Scotty" technique for estimating time.

Takt time and the relationship with the conveyor speed and oven length. Thanks much!!!

We have Mydata and you can print a report telling you the average placement time per part number. I monitored a few months of jobs, broke things into package type, grouped packages with similiar times (such as chip components up to 1206, SO-8,14,16

We have inline reworkers, so this time has been factored in. We currently use Siemens S25/20 machines with M1 systems. The placement machines run a little slower than the AOI at times so there is time to perform review, most of the time. It's not

I tried several times - it squeaked for a while and then silence...

Hello, I am looking for input on the 7 zone convectional reflow oven on the temperature profiling. I having a problem with the flux/solder spattering on the Au cotact fingers. I have ran some experiment with the soak time and reflow time. Anyway,

Hello, Does any one as a database regarding component assemble by hand on a PCB. More accuratelly how much time (per sec) does it take to bend leads on a component(res), time to insert the component by hand, time to solder by hand. Any time base dat

Hi,, My doubt is regarding to the Reflow Time, I mean, in a 5 or 7 zones oves, how long the board should stay inside the oven to complete the soldering cycle? 4 min, more, less...Should I keep low temp until peak for a long time or high temp in shor

John, Your calculation looks fine. If that's all you were looking for your done. If you really want to produce more boards per day we would need more info. Size of board, can it be panelized or larger panel. Your line configuration and what mac

If you stop when the first completed PCB of the next run goes in the oven, wouldn't you be including the loading time for that PCB in your change over time? Wouldn't change over time be from the time your p-n-p machine stops loading the last board o
