How much do you know about OCA Film?

The brief introduction to OCA adhesive glue:
1) So far in the cell phone repair and refurbish industry and consumable material market, there are the different type of OCA glues custom made for iPhone, iPad, Samsung, LG, Motorola, Sony flagship models.
2) OCA optical clear adhesive film is also one of the important raw materials for mobile phone touch screen.
3) The OCA Tape is a highly-specialized film that offers excellent clarity, light transmitting and adhesion to a wide variety of transparent substrates. OCA Optical Adhesives are usually applied in transparent applications, such as in smartphone and tablet PC LCD displays, touch panels and other devices requiring an optically clear bond.
4) These OCA Clear Adhesive Films perfectly fit with your device and need no cutting before applying such as LG G2, G3, G4, Motorola Moto G2, G3, G, Sony Z4, Z5, Samsung Galaxy S6, S6 edge, S7, S7 edge and so forth.
5) We highly recommend professional installation. We won’t be responsible for any damages to your cellphone/mobile phone that you may cause during the replacement for your defective phones.
6) Easy to remove with no glue residue by using the special OCA Adhesive Remover.
Next let’s get a more comprehensive understanding and view of the OCA Adhesive Glue in the aspect of dimensions, property and function of different manufacturers which are Mitsubishi OCA and China Made OCA.
Function Test
1) Light Transmittance Test
The value of visible light test should greater than 90 in terms of qualified OCA glue.
Mitsubishi 250um                                  China Made 250um
2) Release Film Test
Stick the corner of the OCA protective film with easy peel/tear label to see if it can rip off easily. Mitsubishi OCA outperforms China Made in the test.
China Made 250um                               Mitsubishi 250um
3) Adhesion Test
Stick the OCA Optical Clear Adhesive film to one clean cell phone outer glass lens to test if it has strong stickiness and is easy to tear up after fitting.

4) Laminating Test
In the course of LCD screen display laminating and outer screen glass laminating process we can easily check if the OCA can be easily laminated. There is no obvious difference between Mitsubishi OCA and China Made OCA in the effect of Laminating.

5) Bubble Removing Test
After 10 minutes bubble removing process, check the two type of phone screens. Both the Mitsubishi and China Made OCA are in good condition.

6) Bubble Returning Test
After a period of time, check the OCA to see if it has air bubbles in it. The China Made ones sometimes have small air bubbles on both sides of LCD assembly.

7) Repair Test
Separate the LCD display with the machine, then tear up the OCA glue manually to see if it can be removed easily. Mitsubishi OCA can be torn off completely by hand, while China Made OCA can not.

From the test we can draw a general conclusion: Mitsubishi OCA is better than the China Made ones in term of quality.

As for won’t power on accompanied with 50mA-80mA boot current, the first thing we do is to check power supply voltage. If nothing goes wrong, the fault is most likely to be related to CPU. If there is abnormal voltage measured, then check corresponding faulty position on the board. The fault component is finally confirmed as PMIC U7003, our focus today would be to fix this issue. We can fix the issue by replacing with a new PMIC(You can read our another about PMIC Replace Case- iPhone 6 Won’t Turn On Repair – PMIC Grinding and Replacing).

How to Unlock Any Network SIM Not Supported iPhone

Recently, a news spread widely among iPhone users, especially whose iPhone bears Carrier Lock. The news claims that the locked iPhone can be easily unlocked by using a sim card sticker and a column of numbers. REWA LAB has tried and made a video on YouTube. Let’s check out if the news is real.
Inset a CUCC sim card into an iPhone with American carrier lock. And activate the phone.

The phone is unable to be activated.

Then insert the SIM card below the CUCC SIM card and try to active the phone. The phone could be activated normally, and the phone can make phone call normally.

After activated iPhone with SIM card sticker, spread the dialer board and enter *5005*7672*00#, and select carrier. Then select your iPhone model, which depends on the carrier.

After that, enter *5005*7672*00# again and input ICCID code: 8901410427780604313 and send. With OK appearing on the screen, click ‘Accept’. The phone will be unlocked successfully.

The unlocked iPhone can do OTA upgrade, and change SIM card without SIM card sticker. However, if the iPhone is Erased all content and settings, the phone will back into locked status.
Soon after REWA YouTube relapsed, Apple has fixed this bug, the Carrier locked iPhone could only be used with SIM card stick then. Also, they released the solution for iPhone X Face ID not working after change screen, I guess you guys are interested to take a look.

How can I recover the data from my dead iPhone 6S?

A faulty or dead iPhone is a disaster for many people, however losing all the photos and data of your phone without any backup seems to be an even greater disaster. iPhone data recovery thus becomes very important in cell phone repair industry. We are going to show you how to recover the losing data from a dead phone.

Connect the battery connector with DC Power Supply, and press the power button to power on, there is no response from the screen.

However, current reading on the ammeter is normal, which indicates that the phone is turning on yet with black screen.

Our initial judgment is that the display circuit might have been damaged, and we need to check LCD/Digitizer Connector J4200. Run diode mode measurement of pins relevant to display on J4200. The measured value of Pin 33 is lower than normal value, which is abnormal.

Pin 33 is the reset signal pin for display circuit, the reset signal sent out by Pin J3 on CPU reaches Pin 33 via FL4221, C4221 and C4220. Our next move is to detach FL4221, C4221 and C4220 for further measurement.
First, remove sponge around the connector with tweezers.

Then stick High Temperature Protective Tape on connectors around.

Heat with Hot Air Gun at 330℃, air flow 1, detach FL4221, C4221 and C4220 from the board.

Then tear off the High Temperature Protective Tape and run diode mode measurement of the two pins on FL4221. The measured value of Pin 2 is abnormal.

Since Pin 2 is connected directly to CPU, we can confirm now that CPU has been damaged. As we all know, a damaged CPU can not be replaced separately. And therefore the 1.8V AP_TO_LCM_RESET signal cannot be supplied. To avoid data loss, we can recover data by voltage borrowing.

Choose an 1.8V voltage point nearby, For example, C4118 for our course today, which is the 1.8V voltage point of BUTTON_MENU_KEY_L.
First, remove sponge around with tweezers.

Then heat with Hot Air Gun at 270℃ to remove black adhesive.
Run voltage mode measurement of C4118, the measured value is 1.8V, which is perfect for all operation.

Apply some Paste Flux to FL4221 bonding pad, the remove tins on the pad with Soldering Iron at 350℃, prepare a length of tin applied Enameled Copper Wire of 0.1mm in diameter, heat with Soldering Iron at 350℃. With one end of the wire soldered to C4118, solder the other end to Pin 1 of FL4221. Once done, clean with PCB Cleaner.

Now we can assemble the phone and test, Connect the battery connector with DC Power Supply and press power button to power on.The phone turns on normally.

Connect the phone to computer with a digital cable, launch the iPhone Data Recovery software iTools.

Go to Toolbox>Phone Transfer, choose ’Restore backup’, and click on ’Backup’ to start the Backup process. Once finished, save all the recovered data on the computer.

Tips: make sure that the screen stays on during the data recovery process, otherwise the data recovery might fail. Also, this works for data recovery only, the phone is still not prepared enough for normal use. iPhone 6s data recovery from dead board completed successfully.

It is a special case for the iPhone 6S data recovery, if you use others iPhone devices and want to recover the date what you lost, REWA will be your best choice. More info please go to blog.rewatechnology.com
