As I understand it, the BM1384 ASIC is VERY tricky part to get correctly soldered down. Read up on "Ball Grid Array" for more details.
While it is a tricky chip, it's not a BGA - just a custom package akin to a QFN with multiple exposed under pads that are a bit more like an LPCC. You can check the limited datasheet: https://www.bitmaintech.com/support.htm?pid=00720141220132903742H2RLy6C40630While there, check out the BM1382 as well - that one would be worse
