5K DACアンプ


by Qudelix Incoporated 25 May 2020 3 Comments

5K には 3 つの BGA(ボール グリッド アレイ) IC パーツがあります。 QCC5124 と 2 つの ES9128p。

PCB の信頼性と耐久性を強化するために、追加のコスト増加はありましたが、繊細な BGA パーツにエポキシ アンダーフィルを施しました。これらの部品は、はんだ付けとエポキシアンダーフィルで 2 回接着されます。

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!
