Question about reball skywork chip

okay

I have not reballed already because I'm not sure if the big surfaces are coated with solder or with something else?

There is only one part. Your image shows the front and back of the chip. Here are some great instructions about reballing a BGA. Also check this video, different chip, same idea. The stencils for a reball are available at places like this. Hope this helps, good luck.
