Hello everybody! Welcome to keep focusing on FORWARD MACHINE FACTORY if you like it. You can get OCA Lamination Machine Tutorials here for your reference.
The S8 screen needs three repairs and today we want to show you how to frame these screens together using our new special mats.
This particular pad is really useful and practical and may surprise you, it can help you laminate the frame.
Now let’s continue.
The filter we need to service today has been removed and cleaned of glue before the frame lamination.
Now we can proceed to laminate these screens in the frame.
First, our engineer adds the glue to the frame.
Why are we doing this? This is because we don't have the opportunity to add glue to the laminated glass when we laminate it.
We then need to use a very thin protective film and insert it into the cable position.
How will it affect?
It keeps the internal air from forming bubbles during the lamination process.
After the final cleanup, we are ready to start laminating the glass.
The glass we are using here has been pre-attached to OCA.
We will then use this glass to laminate the S8 LCD into the frame.
The next key step is that you can see our engineer first align the side of the receiver hole.
That's because the receiver hole and the hole in the glass panel are more accurately positioned.
It helps us position the glass more precisely on the center frame.
The engineer then uses both hands to align the sides.
Then press the center with both hands to complete the entire positioning.
Next, we had to use FORWARD's special mat to place on the rim of the glass.
Once they are finished, they are placed in the OCA laminator for bonding. The machine we use for this process is one of FORWARD's products - the RMB-2 laminating machine.
For this part, we need to select LCD mode.
The pressure we are using here is 2kgs in the S8 model frame laminate.
We set the vacuum time to 120s and the lamination time to 40s.
As you know, the glass is first secured to the LCD in a frame lamination, so it takes longer for the vacuum to be applied so that the lamination can achieve the desired result.
Now let's see how the S8 laminates.
We can see almost no air bubbles on the screen.
In the next part, we put it in the machine to remove the bubbles.
We can laminate a second screen in between the defoaming, the whole process is the same as the previous one. We will not repeat it here.
After the debubbling process is complete, we can see that the screen is completely free of bubbles.
But we can see that it has a slight crease in our eyes. This slight wrinkle will heal itself in about a day or two, and the screen will look perfect.
In the last step, we put the fixed LCD into a UV lamp to cure it so that the LCD will not bounce back and no reworking is required.
Frame lamination job done.
The tools we use today are very simple. They are the base that comes with our machine, a regular pad and a special pad from FORWARD. By having these tools, you can laminate in the frame.
