With the IR station maxed out to 400 C, the top of the board only reaches 160 C. I wouldn't have thought the board would absorb 240 degrees.

I have lots of flux.

I just ordered some flux paste. I had never heard of flux paste. Solder paste, sure. But not flux paste.

finally heard back from the sale rep

The BGA300 should ship next week and I should have the reballing kit before then. Good news because the ball placement is what I am not sure if I will have the necessary supplies.

here's the way I'm doing the math:

the pins are .27mm wide
there is a .5mm distance from center of pin 1 to center of pin 2
there is no known measurement for the gap between pin 1 and pin 2
however, going from the center of pin 1 to the edge, it should measure .13mm
If we double that the represent the two pins, that gives us 26mm
That would mean the median gap between pins should be .24mm
So if I use a .3mm ball and it overhangs .06mm, there would still be a .19mm gap
