Hello everybody, im not a sound student just a curious person. I would like to know what kind of electronics component is this and what are its uses please its very important.
Maybe a display controller, maybe a clock, or maybe something completely different.
It is chip on board technique. A bare chip (die) is glued on the PCB. Then the connections from chip to board are bonded.
After that there is a black protecting potting material placed on the chip.
