REWA AAA Grade proves to be qualified for the following assembly producing process.<\/p>\n

Digitizer Assembling<\/strong><\/h2>\n

1. Touch Panel<\/strong><\/h3>\n

Adhere the ACF adhesive to the corresponding position of the touch panel.<\/p>\n

Then complete bonding the FPC to the corresponding positions\u00a0of the touch panel respectively.<\/p>\n

After bonding, connect the touch panel to the touch system for function test and run sampling inspection of both defective and non-defective samples of the touch panel with the electron microscope to analyze\u00a0the bonding effect.<\/p>\n

Once finished, deliver the completed touch panel to the next process via the transfer window.<\/p>\n

2. Roller Dedusting<\/strong><\/h3>\n

Use the roller to finish preliminary cleaning of the touch panel.<\/p>\n

3. Glass Cleaning<\/strong><\/h3>\n

In the high grade purifying environment, clean each glass lens with the cleaner.<\/p>\n

4. Glass Laminating<\/strong><\/h3>\n

In the high grade purifying environment, run re-clean and re-inspection process of the glass lens.<\/p>\n

After that, laminate the touch panel with\u00a0the glass lens\u00a0with\u00a0the help of the semi-automatic laminating machine<\/a>.<\/p>\n

5. Bubble Removing<\/strong><\/h3>\n

Put the touch screen assembly on the tray and place it into the machine \u00e0 enlever les bulles d'air<\/a> for 45 minutes. Set the pressure value as 0.6MPa and activate the bubble removing process.<\/p>\n

Once finished, take out the touch screen assembly.<\/p>\n

6. Protective Film Attaching<\/strong><\/h3>\n

Attach exclusive protective film to the front and back of the touch screen assembly for quality guarantee.<\/p>\n

7. Semi-finished product warehouse in<\/strong><\/h3>\n

Once finished, deliver the semi-finished products to the warehouse.<\/p>\n
