So, there’s a key point that you should have an excellent phone repair skill as a repair man or a host to run a repair store to satisfy your customers’ requirements.

By some repair tools and CEO-2+ OCA lamination machine, today we would like to show you an easy and fast way to restore the iPhone11 Pro Max.

Now let’s begin our repair tour.

Step 1 Screen Heating

Heat up the screen on the heating platform. Here please be noted that the temperature of the heated platform should be at 90℃.

Step2 Bezel Removing

The first one we to do is apply the specialized glue remover XII to the gap between the bezel and the OLED.

Then we scrape the cold glue in the bottom of the bezel’s flex cable position with a plastic slice.

Once done, we cut the bracket around the bang with a cut pliers.

Next, we start to take apart the bezel.

For this part, there are two tips we need to be cautioned. One is pay attention to your strength while you remove the bracket. When pulling the bracket out, pressing it down would be more appropriate.

The other is that if the bracket is hard for you to remove, you can apply some XII glue remover on the plastic slice and insert it into the gap to scrape inner cold glue. But can’t apply too much glue remover on the flex cable and IC position.

When we remove the bezel, you should remove one side first and stop at the flex cable position. Then remove another side and stop at the flex cable position.

The following is a key point to remove the bezel of flex cable position. Here we also have two things should be cautioned. One is the plastic slice should be inserted from the right side of the screen where there is a display IC position and then scrape the inner cold glue.

The other is when the plastic slice is slide to the other end of the touch IC flex cable, you should use a soft plastic slice and incline it to slide back and forth.

Well, next is the final part of this step. When detaching the bezel at the bottom area, using both hands to pull the glued bezel out with the parallel. Here the action of your hands is grasp the bezel and lift it up gently, then lower down the bezel.

Step3 Screen Testing

Before the test, we remove the residual glue with a glue removal device.

After that, it’d best to test the display and the touch.

Step4 Glass Separating

Let’s continue to separate the glass once the test is OK.

Before separating the glass, we use a blade to clean up the light glue between the glass and the LCD.

For this step, there are three tips we have to mention. First, the steel cutting wire should be inserted from the side of the flex cables.

Second, you should pull the steel wire with even force. If the left side doesn’t work while you pull the wire, you can change other directions, like right or middle side of the screen.

Third, if you encounter the residual glue while pulling the steel wire, you can scrape it and then move on.

Step5 Glue Removing

For this step, paint a layer of 8333 glue remover on the OCA glue and wait for 30s.

After that tearing off it with one hand. And be careful with force applied. This is to avoid damaging the OLED screen.

Step6 Cleaning

Once finished the glue removing, it’s time to clean the screen with white oil. Here are also two tips we would like to mention. That is, be more careful of the touch’s golden circuit at the edge of the screen during the cleaning and slide the dustless cloth gently.

It’s because if too much force is applied, the touch cable would break and the touch is unworkable.

The other one is while cleaning the flex cables area, the action should be gentle and the white oil can’t be added too much.

Again, once finished cleaning, test the display and the touch.

Step7 LCD Laminating

For this part, we prepare iPhone11 Pro Max’s specialized locating mold in advance.

Then place the LCD flat into the mold so it’s not easy to shift and clean up the dust on the LCD. Here we have to pay attention to the flex cables position.

Once done, take out the glass with OCA and tear off the protective film of the OCA with a pull tape.

Next, align the glass to the LCD and attach it to the right position of the LCD.

After that, press the center of the glass with your one hand and fit it gently with the LCD.

Finally, we put the preliminary pasted LCD on the black magic mat and put them into the CEO-2+ OCA LAMINATION MACHINE for laminating and bubble removing.

For this part, please make sure the flex cable is outside the LCD while you put the LCD on the mat.
