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

How SMT Line Change over is measured?

Electronics Forum | Tue Feb 26 08:52:35 EST 2013 | stephendo

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.

Calculating Reflow Slope

Electronics Forum | Tue Oct 05 20:07:12 EDT 2004 | davef

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

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

Does Anybody Know What Time It Is?

Electronics Forum | Wed Mar 28 17:25:58 EST 2001 | davef

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
