A leaked internal document confirms that the new MacBook Pro keyboard is blocking dust

Conclusion The new MacBook Pro 2018 computer has been dismantled Before the IFixit team did show up and showed us that Apple had made some changes to the keyboard design in order to solve the problems that sometimes caused the buttons to collapse. It is worth mentioning that Apple is facing several class action lawsuits because of this problem which eventually prompted to launch a new repair program for affected MacBook owners as a result of this free problem.

Apple first claimed that the membrane had been designed to make the keyboard quieter, but an internal document reveals that she placed a silicone membrane on the keyboard buttons to prevent debris and the dust to disable the buttons. The document obtained by MacGeneration indicates that the silicone membrane exists to protect the keys of the keyboard. The membrane helps to "prevent debris from entering the throttle mechanism".

This document clearly mentions that there is a "membrane" under the keypad buttons to prevent debris from entering the throttle mechanism. Be careful not to tear the membrane. Removing the membrane will replace the upper structure. "We do not know why Apple does not want to tell us frankly that it has put the membrane there to reduce the problems that have bothered so many users. Maybe that will be tantamount to implicit recognition." that the previous keyboard has an obvious defect, however, your next MacBook Pro keyboard will handle the debris well.
