Tact time as defined by the IPC 9850 standard is "the average time required to place a single component while maintaining the specified placement process capability. Excludes transfer time, fiducial time and nozzle change time." Sounds like what you

Do you also measure job run time? IF you don't I"m sure if the change over time is measured but not the run time then the run time will go up almost as much as the change over time goes down.

We do not know how your KIC2000 calculates slope. Here's an approach to calculating slope: * Subtract the lower temperature from the upper temperature. [Temp upper-Temp lower] = Temp change * Subtract the time when the lower temperature was measured

Tact times published by placement equipment suppliers usually do not account for board load/unload. Placement time standards set for your boards must include load/unload time. I measure from first fiducial read on board 1 to first fiducial read on bo

OK - going to set up some measurements so we can see how big this problem is. I've got the following so far... Number of boards pasted per employee per shift Number of hand placed parts per employee per shift Number of people per shift Time pasting

Grandpa, You got it - Identifying the bottleneck operation is the key. The secret is to design a tool can predict accurately where this bottleneck is. In your formula you can use machine process time, PCB transportation time, part trim time, part in

Just got off the phone after bustin' my brother-in-law about the article in USA Today about all the goofy time zones in the US state of Indiana. Then I saw: * SMTnet Forum time is about a half hour late * SMTnet time on this message I'm posting on
