Yes, a Ball Grid Array (BGA) package would be quite a trick, but that's a Quad Flat Pack (QFP) which isn't so tricky. Still, it's pretty cool. A heat gun, or an industrial hair dryer, in keeping with the housewares theme, would help.

If we go back to etching boards in the kitchen sink then everything can be done in-house.
