Place a Digital CRO on that 24V rail. Watch the output. trigger on voltage drop lets say 18V picking a figure out of the air. You may well have another rail in your supply or nearby pulling your 240V //110V rail. Most likely a shot Electro either on

AN inductor probably 22uH 5A. Check a TDK catalogue http://en.tdk.eu/inductors Another approach is identify the power control IC next to it and look up the App note associated with it, 9 times out of 10 it will be the same as recommended. Are you s

Searching the IPC website is a good start. http://www.ipc.org Some standards you may want to look over are.... IPC 600, IPC 610, J-STD-001 "riveting and circuit cards into metal shelf" definitely has my curiosity level elevated. Since you know your

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

If I understand your question: I've done this before by creating a spreadsheet in Excel. All the data you're looking for can be built into said spreadsheet. I don't think you'll find a "canned" package with the values without buying a bigg-ass prgram
