Introduction

It’s well known that we can get many videos and articles about dismantling the iPhone 11 Pro Max by teardown masters. From those teardown videos and articles, we know that the glass covers of the iPhone 11 Pro Max are the toughest glass that Apple uses. If the back glass of the phone is broken, we have to remove all the components to fix it. It is very troublesome and difficult for some repairers to refurbish the phone, especially because of the triple lens camera system, which makes it much more difficult to repair the glass.

So, isn’t there any useful and practical method to overcome this repair problem that doesn’t damage the OLED display?

I believe that you have tried many methods, including hot separation, frozen separation and any other methods that you know, but with little success.

Recently, FORWARD LAB has tried to use the blue light laser separation machine to repair the iPhone 11 Pro Max back glass and we hope it can enlighten you somehow.

  1. First, place the iPhone 11 Pro Max back glass into the centered positioning mold. Then, use a focal length rod to adjust the distance between the laser head and the back glass. Then, use a focal length rod to adjust the distance between the laser head and the back glass.

  2. Close the door. Select the iPhone 11 Pro Max’s back cover drawing from the model list, then click the “Figures” key - the machine will laser the back glass automatically. Here we can see that the machine is an enclosed structure with a window door and the laser is not exposed. You can observe the laser process at any time and it’s 100% safe and reliable during the operation. What’s more, while the laser machine is working, you can release your hands to do other repair jobs. It’s very convenient.

  3. Once the laser is finished, take out the phone and give the back glass a little tap with a focal length rob. The back glass would appear with some cracks, it would be easier to separate. No need for too much force. No need for too much force.

  5. The glass around the triple-lens camera is relatively thick and the glass in this area is harder to remove. No matter how hard it is, you still can find a way to overcome it. If you are not able to tear down the glass in this area, you can laser the glass in this area one more time. Here, the engineer is using a blade, a grinding tool, a sculpture knife to remove the glass in this area.
