Lots of times the suppliers define pin on with a mark on the part molding. Often, they define their approach on their data sheet.

Intel uses the dot in their letter "i". Hmmm, go figure.

Not these days. Most parts have several molding marks. Or the entire edge has a bevel. Using the ink as polarity is becoming mainstream.

I'm building a circuit board by hand and can't identify pin 1 on a smt IC. I always determine this by the beveled edge, which this part has, but it also has an arrow on the opposite end, so now I'm unsure which one I should go by...help! Ok, got my
