IC Chip Orientation - Ocelot Build

[jdduffield]

Do I have the IC chip orientation correct on these? I think I’ve got it right but double-checking before soldering them down because there are seven of them and I’m not using sockets.

I always thought the dot aligns with the side containing the arch marking and square pad. However, in this case a couple of them have the arch on the chip itself and the dot on the opposite side. Confusing. The reason I think I’ve got it right is because the build doc shows a mod to “pin 7” (for older boards only). I know I don’t need the mod as this is a “Revision 2” board. However, I was able to gather from the photo example that pin 7 was opposite from the arch marking.

yep you're good

On the ICs with the arch, that is the pin one indicator. The other marks are mould ejector pin marks

On the dome ICs it is pin one. The others are die ejector pins while some of them have the dome on the chip itself and the dot on the opposite side.
