5K verfügt über drei BGA-IC-Teile (Ball Grid Array); QCC5124 und zwei ES9128p.

Um die Zuverlässigkeit und Haltbarkeit der Leiterplatte zu verbessern, haben wir diese empfindlichen BGA-Teile mit Epoxidharz-Unterfüllungen versehen, allerdings mit zusätzlichen Kostensteigerungen. Diese Teile werden zweimal mit Löt- und Epoxidharz-Unterfüllungen verbunden.

I was able to find this on one of their other posts. *ESS discontinued ES9218. From Nov 2021, 5K DAC/AMP is manufactured with ES9219C, which is pin-to-pin compatible with ES9218P.

Following up on Joao’s question above. All the PCB photos show ES9218… was there a change in design since the photos were taken?

ES9128p??? Could you decide what chip it has? In one page it´s the 8218p, in other 9219c and now 9128p!
