Vishy, We have a project to study the impact of productivity lift in SMT lines using discrete event simulation tools (AutoMod is what we use). As Mr. Lahat found out, the high fidelity simulation of productivity lift is non-trivial. However, we have

Roni: that's some news...do you have more details...you can email me, if it's not confidential.. by the way, what does Arena simulation software do ? aside to all smt-netters : Have you heard of any other SMT line simulator software ? pls. lemme

Would something like this work? http://www.patientliftusa.com/products/electric-patient-lifts.html You would have to build a custom harness to match your fixture but it is in the $1K-2K price range.

Vishy, I was in the same boat. I had to run 3 siemens smt lines and get good results. I used the Arena simulation software to program in my 3 smt lines and found it very complicated but can be done. In parallel I took in industrial engineering stude

Dear all There are alot sockets in our products,BIB.These skts are lifted abit after being solderd with wave machine.If the skts become lifted, how much tolerance of the high is acceptable? as example 1mil~5mil,or,1mil~8mil. Pls advise me. Thanks in

Your customer is correct. Your supplier has clamped some sort of machine to your butt and has plugged it in the wall outlet. Honest mistake: * IPC-A-600H, 3.3.2 Lifted Lands - (Cross Sections) ... pertains to boards that were cross sectioned after t

When considering a new semi-automatic stencil printer, for low volume high mix production, could anyone elaborate on the benefits of vertical lift-off versus a Clamshell design? Money can be saved with a Clamshell design, but what specific limitatio

If I would need to investigate this claim, I would ask the following questions: - was traceability used when this product was manufactured? - was testing mandatory when this specific product was built? - is the test covering the QFP we are talking ab
