Does anyone specify on their electronic parts drawings orientation of parts on tape and reel? Our assembly people have had some reels of parts from different manufactures come in with a different orientation. We could put EIA-481 on the drawing to try and hold the manufactures to a consistent orientation. Then main problem we would have then is with diodes or polarized capacitor. The specification references pin 1 for orientation. I don’t know of any agreed upon standard to what is pin 1 on a diode or polarized capacitor. Does anyone have experience with this or have a suggestion?
