手順6
Much like the Function Keys model, the trackpad in the Touch Bar unit slides out easily after dispatching ten T5 Torx screws. We can also happily report that the trackpads from these respective models are identical, and likely cross-compatible.
  • Much like the Function Keys model, the trackpad in the Touch Bar unit slides out easily after dispatching ten T5 Torx screws.

  • We can also happily report that the trackpads from these respective models are identical, and likely cross-compatible.

  • The cable routing, however, is different to accomodate the modified logic board design. So, if you're planning on replacing a busted trackpad, be sure to hold on to the original flex.

  • In case you missed it, here are the ICs we identified the first time around:

  • STMicroelectronics STM32F103VB ARM Cortex-M3 MCU

  • Broadcom BCM5976C1KUFBG Touch Controller

  • Maxim Integrated MAX11291ENX 24-Bit, 6-Channel Delta-Sigma ADC

  • Monolithic Power Systems MP24830 white LED driver

In modo molto simile al modello Function Keys, il trackpad del Touch Bar scorre fuori facilmente una volta liberato da 10 viti Torx T5.

Possiamo anche riferire con gioia che i trackpad di questi rispettivi modelli sono identici e probabilmente intercambiabili.

Il passaggio dei cavi, invece, è diverso per farci stare la scheda logica modificata. Quindi, se prevedi di cambiare un trackpad guasto, assicurati di tenere il cavo flessibile originale.

Nel caso che tu te lo sia perso, ecco gli IC che avevamo identificato nel primo giro:

MCU ARM Cortex-M3 STMicroelectronics STM32F103VB

Controller Touch Broadcom BCM5976C1KUFBG

ADC Delta-Sigma a 6 canali e 24 bit Maxim Integrated MAX11291ENX
