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.
6Mitsubishi 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.
7China 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.
8
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.
9
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.
10
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.
11
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.

How much do you know about China made LCD screen

The LCD screen can always be a fragile part compared with other parts within your phone. Once it’s cracked, you have no way but to repair it. With Apple support, you get an Original (OEM) LCD Screen with a high price. With a repair shop, you are most likely to get a China made LCD screen with a much lower price. Yes, because of the lack of iPhone original LCD screens, more and more independent repair shops have turned to China – the world’s factory for replacement parts. Tagged as less expensive than OEM products, China-made LCD screen stands for a potentially worthwhile choice.
Recently REWA has got some exclusive samples of the Tianma-made iPhone 7 LCD screen, did full tests with these samples and found some differences compared to OEM screens in the aspects of appearance, structure and function etc.
In following photos, the white color sample is Tianma-made, while the black sample is OEM.
Dimensions
From the above test data, we can observe that the screen thickness parameter is different. The Tianma-made screen is much higher than OEM screen. The reason given for it is that these two LCD screen structures are different.
Qualified Alternative – iPhone 7 TM Screen Dimensions
Home Button Hole
As for home button hole alignment, there are no differences between OEM screen and Tianma-made screen.
home button fitness -iPhone 7 TM Screen
Flex CableAlso affected by the difference of structure, there are some differences between Tianma-made screen flex cable lines and OEM screen flex cable veins.
The left screen is OEM, the right one is Tianma-made.

Structure
Tianma-made iPhone 7 LCD screen features with a conductive layer of ITO, while OEM screen is using an In-cell program. And this also explains the increase of screen thickness.

Tianma-made screen may be relatively falling behind in laminating technology, it proves successful on display and touches function test. The truth is that they do differ from each other, but the Tianma-made screen can also be a good replacement for OEM screen for those who want to cut repairing cost and get an affordable one.

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.
How can I recover data from dead iPhone 6S
However, current reading on the ammeter is normal, which indicates that the phone is turning on yet with black screen.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
Then stick High Temperature Protective Tape on connectors around.
How can I recover data from dead iPhone 6S
Heat with Hot Air Gun at 330℃, air flow 1, detach FL4221, C4221 and C4220 from the board.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
Connect the phone to computer with a digital cable, launch the iPhone Data Recovery software iTools.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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

3. Your phone dies quickly: If you’re not playing games, listening to music surfing the web, using Bluetooth or doing something else that may be causing your battery to die. However, a battery that dies very quickly after it has been fully charged, may also be a classic sign that you need a new battery.
4. Your battery or phone starts getting very hot: It is actually quite normal for batteries to generate heat when charging, but their heat is internalized. Batteries that need to be changed, are those that generate or cause the phone to generate external heat.
5. Your battery bulges: The bulge in a battery means that the internal cells have ruptured and that simply means that the battery needs to be changed.
