2019 MacBook Pro teardown suggests butterfly keyboard changes



Not long after Apple announces a new product, the people on iFixit start working on a teardown of Cupertino's latest device. On Friday, the team launched its first look at the 2019 15-inch MacBook Pro, which was unveiled earlier this week.

201-inch MacBook Pro 15-inch is similar to last year's model, launched just 10 months ago in July. The most critical change, as well as the updated internationally available, is the introduction of new components for the device's butterfly keyboard. This time, Apple has changed the material it uses to the internal keyboard mechanism.

Apple has had problems with the butterfly keyboard in recent years. Specifically, many users have reported handling broken or sticky keys. To solve this, Apple has recently expanded its keyboard service application to include every machine that has a butterfly keyboard, so they are covered at no additional cost. Apple also promises to speed up keyboard repairs for these users.

So did the Apple repair the keyboard?

It will take some time before we know for sure if the latest butterfly keyboard is a success. According to iFixit, there is a new silicone membrane that goes with a latest butterfly mechanism. Where last year's transparent switch cover material was described as "semi-opaque, a little sticky and feels like silicone", the 201

9 model is "clearer and smoother to touch."

To confirm that a change has occurred, iFixit analyzed material using a Fourier Transform Infrared (FTIR) spectroscopy. The device works by shining infrared light at the material and measuring how much light is absorbed and at what wavelengths. This data acts as a fingerprint that can be used to identify the content. In this case, the iFixit has determined the material of the 2019 MacBook Pro is polyamide (commonly known as nylon).

The people on iFixIt have also determined the metal dome switch for each key may also have been changed, but several tests may be required to confirm this.

Best guess about their composition: Ferritic stainless steel, with a thin polymer coating on the bottom. The difference in surface finish from the 2018 version (left) to 2019 (right) indicates that Apple may use a revised heat treatment, or alloy, or possibly both.

Bottom line: Apple has probably ] made changes to the butterfly keyboard of the new MacBook Pro. However, only time and customer use will tell us if the new components are an improvement. It should be noted that the 2019 MacBook Pro is already on the list of computers supported by the Keyboard Service Program. At least we know what keyboard problems will appear will be addressed for free.

We continue to follow this story and let you know if more information is revealed. Meanwhile, be sure to leave your comments on the problem below.

More powerful than ever


MacBook Pro with Touch Bar

Now with an improved butterfly keyboard

Apple introduced a major update for the MacBook Pro with the Touch Bar model with a new 8-core processor that makes its portable laptops more powerful than ever. It's now twice as powerful as the old quad-core model and 40% more powerful than the old six-core model. (F, b, e, v, n, t, s) {if (f.fbq) return; n = f.fbq = function () {n.callMethod?
