Hi
I had about 11 pieces of this small BGA chip, which most of the time along with its bigger ones are the highest yield of IC chips.
Again, since I am so lucky I get the ones that had zero nada gram of gold instead only copper bond wires.
Here is the chip I processed there were 10 more that I did all together
Here is the interior after removing the black epoxy all bond wires are copper
This was a toll refine so, not all BGA chips are the same and have gold. A test always required.
