  • Next, we can remove the Bluetooth board from the iMac.

  • With the help of our trusty iFixit vise (which is made of the same material as our spudgers, and is ESD-safe), we're able to desolder the shield covering the little Bluetooth board to reveal the chip goodies underneath.

  • At its heart lies:

  • Broadcom BCM2046 Bluetooth IC

  • 256 KB of SST 39VF200A CMOS Multi-Purpose Flash (MPF)

  • We found this same chip a long time ago in the first MacBook Air.

接下来，我们可以从 iMac 上拆下蓝牙板。

值得信赖的 iFixit 虎钳（与我们的铲子采用相同的材料制成，并且防静电）的帮助下，我们拆下了覆盖在小蓝牙板上的屏蔽罩，露出了下面的芯片。

其核心在于

Broadcom BCM2046 蓝牙 IC

256 KB SST 39VF200A CMOS 多用途闪存 (MPF)

很久以前，我们就在第一代 MacBook Air. 中发现了同样的芯片。
