Cracked Screen Testing

We should test the display, the touch of the screen and make sure they both still work well.

OCA Laminating

For the OCA lamination, we need to stick a new piece of the OCA to the new glass by using the special molds for S8 and RMB-2 laminating machine. We should select the mode of OCA laminating in this process. Besides, we need to set up the time of vacuuming to 40s and the laminating time to 40s.

After the lamination, we would check if there is any bubble on the affixed glass with the OCA or not? If we see the bubbles on the glass obviously, we should put it into the bubble remover to remove bubbles. At this time, we need to select the mode of OCA bubble and set the bubble exhaust time to 180s. Once done, we can see that the glass looks perfect without any bubble.

Warm tips: The key part in this process is to align the position of the molds, so you must make sure all the molds have been calibrated before you put the molds into the RMB-2 machine. Moreover, the smooth side of the silicone mat should face up on the molds.

But in this step, we have to turn over the silicone mat, let the flex cable side face up on the mold and make sure the flex cable with the screen is outside the molds. Besides, we have to locate the positions with the molds and the position of the LCD and the glass.

After the alignment, we put the molds into the RMB-2 machine and select the mode of LCD laminating. The time of vacuum should be set to 40s and the lamination time to 40s.

Then, we need to look for the bubbles and put it into the bubble remover if it has bubbles on the screen. The bubble exhaust time is 300s.

Here we can see the screen looks perfect without any bubbles, so the LCD lamination job is finished well.

Repaired Screen Testing
