The most troublesome problem of using the mobile phone touch screen laminator to paste screen production is that the paste screen has bubbles. How to solve the bubble problem of the touch screen laminator? Here will explain the solution of the touch screen laminator:
1. When using the touch screen laminator to paste the screen, the oca dry glue should be applied neatly without obvious bubbles, and dust should not fall into the LCD screen.
2. When placing the glass cover, there should be no excessive adhesion, and it should not be attached too tightly. Otherwise, the effect will be worse when it is attached.
3. At present, touch screen laminating machines generally use thermal laminating technology, so when setting the temperature of the laminating machine, the temperature should not be too high, and the temperature and constant temperature should be set within 45 degrees, otherwise it is easy to appear bubbles again
4. Try to choose good materials for the OCA materials you buy. The best one is Mitsubishi OCA glue.
5. When the vacuum bubble remover machine remove bubbles after bonding, the pressure should be controlled between 5 and 8 pressures, the temperature should be within 30 degrees, and the time should be 10 to 15 minutes, so the effect of bubble remover is best, and there will be no air bubbles.
