  • BY-3200S further improves and adds practical functions on the basis of BY-3200
  • The digital display increases the current of the motherboard in working state (When the output terminal is connected to Type-C line, T line or L line, the display tube will display the working voltage and current of the motherboard) 
  • A Type_C interface is added to the input port, and the input port can be directly input by an 87W-140W Type_C charger, and instead of 220V DC power supply (Convenient for maintenance personnel to carry and operate) 
  • The output port adds a Type_C interface, and the output port can be connected to the Type_C output line ,and the application range is wider and more convenient   
  • The LCD ON/OFF switch is used to control the LCD digital tube display and power input (when the switch is pressed once, the digital tube is turned off or on; when the switch is often pressed for 3S-5S, the power input is turned off, and when it is necessary to turn on the power input again, You need to press the switch 3S-5S)

2. When charging the mobile phone or tablet, the output voltage of the DC power supply can also be kept at 20V (BY-3200S will adjust to the corresponding voltage through the CC line inside).
3. The output voltage of the DC power supply is set to 20V-21V, which can be used for 2008-2022 MacBook charging and single-board booting.
Type_C connect input, Support 87W-140W USBC charger input

In Union Repair store, we grade our iPhone screen into 5 different types of quality on the basis of different material assembled. The following is the full details of each condition.


After Market Basic

It is with widely accept major complaint replacements for original parts, which keeps a right balance between price and quality. It has sustainable supplying chain in China, and all the components of the screen are copy quality. Typically, the LCD screen is from several different factories, the most popular 4 on China market are JK,AUO, LongTeng, and ShenChao. By comparing the brightness and sharpness of the LCD, we found JK is the best quality among them and the second best is AUO. No doubt, the other components on the screen are all copy.


After Market Standard

It is better than After Market Basic cause it comes with original laminated flexes and the LCD panel. Other components like touch panel, frame(hot pressed), backlight, polarize lens, and OCA is all copy from different factories.


After Market Selected

The core components (like LCD and flexes) is 100% original pulled from used iPhone while the frame and touch panel is copy. The touch panel and frame come together with cold pressed glue and assembled together with the LCD by the capable third-party factory which keeps its excellent quality. 


Original Pulls

No doubt, it is tear down from used iPhone with all the parts 100% original and working perfectly just like an original new screen, it has whatever the original new screen has. The only complaint about this quality is that some of the displays are with 1 or 2 scratches but still be welcome by our critical customers who are requiring good quality.


Original New

It is 100% original from Apple-authorized factories like Toshiba, Sharp, and LG. We get this kind of screen from the first level dealer. The touch panel of the screen is oleophobic coated which prevents from fingerprints when using your iPhone. And starting with iPhone 7g, the backlight from different authorized factories comes with a different code. Backlight from Sharp has the code begins with DKH/CON, from Toshiba begins with C11/F7C/FZQ, from LG begins with DTP/C3F.
