one of our chip shooters is dropping a lot of parts, the problem i have is i can not tell which manufacture it is. Can anyone out there help me locate a list with electronic manufacture symbols on it?

For chip components it is very hard to identify specially the capacitors. You could get sample of each chip manufacture and compare the color. This is very labor intensive task. I suggest to sort by value ( capacitance, resistance) than by manufac

Or do you mean who manufactured the machine? If so it should have a serial tag, if not it's been butchered by a third party.

Sorry I should have made it more clear. My operators are not identifing the parts after a job is run, all they are doing is bringing me a bag of parts at the end of a shift. By knowing the manufacture, i can look it up in our oracle system to identif

On a gold plated PCB, when in the PCB fab process is the gold plating applied? How about OSP, when in the process is OSP applied?

Try this: http://www.tkb-4u.com/code/smdcode/indexsmdcode.php for starters. I'm curious and a little confused, though.....how is knowing who made the part going to reduce/eliminate dropped parts?

Pretty labor intensive operation as has already been mentioned. Bang for your buck is about zilch unless you're dropping expensive stuff at alarming rates. If you're not doing it already I'd start logging missed picks/drops/rejections and figure out

Does anyone know where i could find a complete resource (internet preferable) on the effect of using SMT with RF manufacturing applications. Is there any special implications?
