Hello, I'm a student assistant in a research project that deals with the simulation of PCB assembly systems. At the moment I collect information about SMDs. My problem is how to assign the correct feeder width to various devices in a simulation. Is

Has anybody heard of a shield to shield the cutter from flying leads during hand cutting of through hole components. If it collected the leads also that would be helpful. I am thinking of plexiglass or something that the board could be placed under.

thank you, Dave, I replied to Tal's e-mail. I am not aware of any formula used to determine the tolerances. We were collecting data from Topline, Siemens and other component supplier. On small components, the aim was to detect components on the side

Thanks. That is exactly what freaked me out. We run Impells and so are not excited about pushing the 'waste' out the 'stack'. I imagine we'd just cut the line and divert the stuff to a collection reservoir.

For the reflow process check out KIC THERMAL at kicthermal.com. They make a product called 24/7 which can collects data for process capability. I beta tested the unit about 2 years ago....interesting stuff.

Phil, is this a post or pre reflow application, it makes a big difference on how you collect and use the data.

Its a shame no one has input on this. We are in the same spot as you. We have been looking at Filemaker to create our own system.
