  • REWA Review on Three PCB Holders for iPhone Logic Board Repair

    REWA Review on Three PCB Holders for iPhone Logic Board Repair

    As an indispensable tool of mobile phone repair, the PCB holder also attracts the attention of repair technicians. What’s the difference among commonly used PCB holders? Which PCB holder is the right choice? Today we will bring you a review on three commonly used PCB holders.

    The first one is a basic and universal PCB holder. Made of synthetic stone that can prevent heat dissipation, the universal holder features a simple structure with movable bayonets and a positioning screw to secure the logic board.

    Universal PCB holder With a double steel-plate base and sponge mats on four corners of the base, the universal holder is stable for usage.  It’s very easy to handle. Still, when adjusting the bayonet, we need to stay away from important components on the board to avoid damaging them.

    The biggest advantage of the universal PCB holder is that it works with all motherboards. Not only iPhone logic boards, but also motherboards of Samsung, OPPO, Xiaomi, and some other phone brands. So, as we can see, the universal PCB holder is easy to use, practical and cost-effective. It is definitely the right choice for personal usage and small-scale repair shops. Now, let’s move on to the next PCB holder. Made of synthetic stone in more smart design, together with 7-shaped buckles and dovetail buckles to secure the logic board, this PCB holder is specially designed for iPhone logic board, applicable to iPhones from iPhone 5S to iPhone 8P.

    With a double steel-plate base and antiskid rubber mats on four corners of the base, this PCB holder also features hollow-carved design on the base for heat dissipation. Moreover, we can put moist sponge mats under the logic board to prevent pseudo soldering when operating. Those buckles on this specially designed PCB holder will bring no damage to tiny components on the logic board. iPhone logic boards fit in the holder perfectly. There are also six IC slots on the PCB holder for CPU (A8-A11), NAND and PCIE.

    There is a slot at the top of these IC slots. This is the slot for components detached during the repair. All in all, this specially designed PCB holder is very practical, especially for those repair shops who work mainly with iPhone logic boards. Here comes the last one. Also a specially designed iPhone logic board PCB holder that is applicable to iPhones from iPhone 5s to iPhone 8P.

    Made of synthetic stone, together with a double steel-plate base and antiskid rubber mats on four corners of the base, this PCB holder also features hollow-carved design on the base for heat dissipation. Yes, just like the previous one. Buckles on this holder also bring no damage to components on the logic board. This specially designed PCB holder features a relatively large operating area that supports two logic boards at the same time. One with the front side, the other one with the back side. We can also see that there is a slot on the left that can be used to place components detached during the repair.

    There are also some upgrades on the IC slots comparing with the previous PCB holder. Besides these IC slots mentioned above, there are also IC slots for A12 CPU, PCIE 2, and three additional slots for home button repair. Which makes this PCB holder applicable to different repair cases. A22 PCB Holder is also currently used by REWA technicians. We highly recommend it to those with batch repair needs.

  • How to Fix iPhone X Camera Not Working Issues – Logic Board Repair

    How to Fix iPhone X Camera Not Working Issues – Logic Board Repair

    The iPhone has a very precise motherboard. Once the phone falls, it is easy to affect the shooting function. Today, REWA LAB will show you how to solve the camera not working problems on iPhone X.

    Cosmetic Inspection

    First, run cosmetic inspection. The board hasn’t been water damaged or dropped.

    First, run cosmetic inspection. The board hasn’t been water damaged or dropped.

    Test & Assemble

    Second, get the motherboard installed and test. Get a known good iPhone X back glass assembly then get the motherboard well installed. Connect the power flex cable, the charging port flex cable, cameras, etc..

    Key Tips: It’s necesarry to connect the earpiece speaker and sensor flex cable. Otherwise the screen will dim after booting up.

    Second, get the motherboard installed and test.

    After finish the assemble, turn on the phone. Tap ‘Camera’ icon and enter into camera mode. We can find that the front camera and the rear camera can not be activated. What’s more, the flashlight also can not be activated also. Judging from this, we need to focus on the rear camera circuit.

    Diagnosis

    For better inspection, tear off sponge around connectors first. Then we should check the motherboard under the microscope. We can find that one component next to the power flex cable has fallen off the board.

    Let’s attach the motherboard to the PCB Holder. For better inspection, tear off sponge around connectors first. Then we should check the motherboard under the microscope. We can find that one component next to the power flex cable has fallen off the board.

    Our guess is that due to improper operation, the component was pried off when the power flex cable was disconnected by the unknown repairman. Beside, the bonding pad has also been pried off the board.

     Next we need to open the point map and find the relevant component information. Here we recommend using REFOX. A concise and smooth bitmap software that provides reliable schematics and board files for Apple/Samsung/Huawei (so far) motherboard repair.

    The missing component is inductor FL3903 which is the protective inductor on the 1V1 power supply line of the rear camera. Since the bonding pad has also fallen off the board, we need to connect Pin 1 of FL3903 with Pin 1 of C3928 by jumping wire.

    Jump Wire

    Jumping a wire between the two pins with Soldering Iron.

    Solidify the board under UV Dryer Lamp for 5 minutes.

    Here are the specific steps:

    Assemble & Test

    assemble the phone and test

    Finally, we can assemble the phone and test. Tap ‘Camera’ icon and enter into camera mode. The front camera and the rear camera work normally.

    Warm tips: get the phone full assembled after confirmation of fault clearance.
