It sounds like a COB device, as others have said. Probably not a PIC or
other low-quantity device, but one made by an Asian maker specializing in
low-cost chips (PICs are far too expensive for this kind of product, and
lack voice and other features).

That's kindofageneral question.. if it's COB you are looking for, there
are assembly houses, but most of that kind of product is very simple,
only a few components. Yield tends not to be all that high, even so, so
the bad ones just get tossed.
