Two questions:

1. What chip is it? I mean, does it have leads or just pads, is it
bga, qfp, qfn, csp, etc? A specific part number is best.

2. Have you made the board for it yet?

Bonus question:

∗ What's a bouth?


I've had luck soldering tiny qfn (no leads, just pads on the bottom)
chips using solder paste and a hotplate, but it helps to extend the
board's pads away from the chip enough to do manual repairs.
