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.
