but I think we are still good.

The correct package has even bigger balls and .3mm diameter. So going with a .3mm ball would be perfect.

I think.

welp, I've got nice headache going so I guess I'll be staying in tonight.

probably for the best, I'm going to hamburg next weekend to spend an awful lot of money on suits so I can't really afford my usual bar tab anyhow :/

heating the chip itself with hot air set to 350 C results in a consistent temp of 180 C. So the chip is absorbing 170 C.

So if the solder has a melting point of 158C, I should be good. There is a 20 degree difference between top heat and bottom heat, which is going to have to be acceptable. I may start off with a lower hot air temp, maybe 320 C. That should result in the top heat being 160C and the bottom heat right about 160C. If I don't get good results, I will have to step up the hot air.

I'm not sure if I want the hot air to be 30 degrees hotter than the board temp. I think I would rather have both temps be as close as possible. I could just heat for a longer period of time. That way the heat distribution should be pretty even.

The NFL now wants London to have its own NFL team and play every team in the United States - or so I read...

I think we could sustain a few a NFL teams here in Europe, probably not enough for our own conference though, which would logistically make it a PITA having to constantly fly teams between Europe and the US.

I think every country has an amateur american football league, so we could probably come up with enough skilled players. I used to be a power back for the local team, didn't play more than 2 seasons though.

yeah, 'fraid so. American football is probably less popular here in Europe than soccer is in America, at least it seems like you guys have a sort of professional soccer league.
