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

Hi Abbas, Dave gave you a lot of sources which cover I think almost all topics in this field. Like in a search function if you are interested in specific topics could you please specify what you are interested in so that ones knows what answer could

100 MHz or Mbps and BT => BaseT => Base Ten. You can purchase interface cards from a variety of sources on the net (www.milestek.com is fairly maroon compliant, which is why I like 'em). In addition to the interface card, each type of point-to-poin

I have the opportunity to pick up a used 1998 Heller 1900WN reflow. I have no experience working with Heller reflows, nor have I heard much about them, so I don't know if they are good quality machines or not. I have concerns about issues such as z

Glenn: Greg's comments about Heller ovens are well taken. Heller sells more ovens than anyone. Beyond his and others general comments, you should be aware of concerns about buying used equipment. Suggestions are: 1 Check the temperatures of conc

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

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

From my experience: It's depends on your messurment tools and the component: - Average high (at least 3 messurment points) should be 6 mils max. (you'll always get pick points of 4-7 mils!). - It depends on component tech./pitch: in pitches great

My company is considering purchasing a depaneling press from Pioneer-Dietecs. Our initial evaluation has been very positive; however, in a recent meeting a question was raised about the amount of stress induced in the pcb/components during depanel.

we have looked into a number of depaneling machines and can't justify the cost. what we are trying to do is to eliminate failures due to part stress when employees are breaking out the boards by hand. I heard about pneumatic scissors one day but to
