Hello, I would like to request some information regarding the interfacing of SMT machines. i am of the understanding that it involves some interfaces like SMEMA 1.1,1.2 and SMPI. I would like to know more about the interfacing of machines using these

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

Certainly automatic placement, preferably with vision system assistance will yield a more repeatable process. Process repeatability (paste deposition, connector placement, reflow cycle, etc.) will be your key to success here. Another possibility yo

I don't think it is a good idea to run your own board in house. The cost will be higher than let the contract out company do it for you. If you are looking for a Smt line.. You must spend atleast $400.000 for an use equipment. Printer= $100.000 Pick

Hello Russ, I believe that the dullness in color of the solder joint is related to the gold finish on the pads. I have had done alot of thru hole soldering of gold pins as well as SMT on gold finish and have seen the condition that you are talking a

A really nifty nest can be made by making an RTV mold of the first side of your assembly. Assuming all are identical within some small tolerance, the resulting mold holds the board very securely and distributes the loading. Cover the components with

Dave, the zero-defect is impossible through my understand in a high volume or proto run manufacturing. Base on theory i have read, yes of course it should be. but practical side of view, it is impossible. you are talking about plenty of variable to

sin: You're correct, there is no defect reduction program that's perfect, in fact nothing is perfect!!!! That's why people talk about 6 sigma and not 20 sigma!!!! If you had a perfectly controlled process, you'd still have defects due to random va

I am interested in discussing AOI. I am looking at introducing a system to a new SMT line. I am very interested in hearing from someone with MVP, MVT, Kestra, and CRTechnologies. The combo of x-ray and 2D inspecion that CRTechnologies offers is very

Bill S. is correct on the positive effects of the Smartsonic 440-R SMT detergent. We have been using this in conjunction with a Smartsonic 4200-2D ultrasonic washer that is equipped with a tank heater set at 100'F. Our suggested process window to p
