Today we will introduce the new REFOX boardview software. Boardview software is an indispensable tool for phone board repairs. The circuits on the motherboard are intricate. Sometimes it is very difficult for us to recognize each circuit just by the appearance. Moreover, there is no way of knowing the contacts of each component.
However, boardview software distinguishes and marks each component on the motherboard. It can help us determine if the components have contact, which can substantially increase the efficiency of troubleshooting.
We can get a lot of information from the boardview software. There are two main sections of the boardview software. Simply put, the bitmap tells you the location and name of each component, while schematics tell you what each component does.
For starters, we can know what the component is through the initial letter. C is the capacitor, J is the connector, R is the resistor, U is the chip, and L is the inductor. The color can tell you the function of each area. The gray areas are grounded while blue areas are empty with no use. The yellow areas serve as signal or power supplies.
Last but not least, we can quickly find the contact components through clicking one component. In the split view, by clicking one component of the bitmap,the schematics will automatically jump to the corresponding component.
In addition to the above functions, resistance values can also be viewed in REFOX boardview software. You can even define your own resistance values.
Next, we will show you how to use the REFOX boardview software with a repair case. The iPhone 12 won’t turn on.
Then we need to take out the motherboard for further testing. Heat the phone with a heating pad and remove the screen with an opener.
It can be seen that the area around the display connector is severely corroded. Clean the corroded area with PCB cleaner.
Install the screen and plug in the direct current supply. Prompt a boot-up with tweezers. The boot current is fine but there is nothing on the screen.
Then we measure the diode values of the connector and compare the measured values with the values on the boardview software. The measured values do not have to be the same but the differences shouldn’t be large. When measuring pin 14, the diode value turns out to be abnormal.
Open the bitmap and find pin 14 of the connector. Click it and we find it has contact with one inductor.
The inductor has been corroded away from the motherboard. Next, we need to install a new inductor. Open the split view of the boardview software. Clicking the inductor on the bitmap can bring you to the inductor in the schematics. Judging from the schematics, the inductor is 700HM. Then we need to install an inductor of the same value.
In the first place, apply some flux and middle-temperature solder paste. Solder the inductor with a hot air gun at 380 °C.
After the motherboard cools, measure the diode value. The diode value returns to a normal value.
Then we put the motherboard back on. The phone turns on and that is a repair done.

Battery repair is a common repair case every day. Today we're going to share with you the steps and details we need to pay attention to when replacing the battery cell.
Firstly, we use a clamp fixture to separate the phone
Remove the battery
Then we need to solder the BMS board of the original battery to the new battery
Remove the protective tape on the BMS board
Disconnect the cathode and anode of the battery with a pair of scissors
Please do not break the flex cable
Remove the original battery BMS board
Pry apart the anode tab and cathode tab
Place them on the welding clamp fixture
Put the battery cell with nickel-plated tabs onto the welding clamp fixture\
The cathode tab and anode tab are settled under the BMS board
Please align the anode and cathode respectively
Solder with the Spot Welder
Note that one end of the spot welding pen is placed on the conductor material (copper)
The other end is placed at the point to be soldered
Folder well the tabs after soldering
Apply the protection tape
Put on the protection bracket
Wrap another layer of protection tape on the outside
Connect the programmer to the laptop
Open the software
Click reading the battery data
Select the data that needs to be rewritten
Recalibrate the cycle times and battery efficiency
Click writing, and then the recovery
Disconnect the cable
Connect the power cable to turn on the phone
“Important battery message” is displayed
Turn off the phone and take out the battery
We install the new battery
It will be verified automatically by the system
There is no “Important battery message” now
In daily repair work, whether it's a simple screen & battery replacement or high-temperature soldering, we all need to open the phone. How to open the phone safely and efficiently has always been a hot topic.
The traditional way of opening a phone is to use a hot air gun for pre-heating, which is time-consuming and hard to achieve even heating. After heating, the strength of lifting the screen by the suction cup is tough to control. If you are not skilled enough, you can easily break the flex cables.
Apple has recently launched its self-service opening tools, including a heated display removal fixture. The tool is not only big and hefty but also expensive.
Today we will introduce the latest REFOX phone opening solution.
In the first place, we use the heat mat to heat the phone. Set the temperature to 80 °C. We measure that it only takes about five minutes to heat up to 80 °C.
The temperature variation between the front and back of the heating area is about 20 °C, so there is no need to worry about burning to the working table. Compared with the hot air gun, the heat mat heats up fast with even heating to soften the adhesive quickly.
Next, we place the phone back down on the heating mat for 5 minutes. After heating, we use the opening tool to open the phone. For starters, we turn the dial on the right to the top.
Then lift the upper body of the opener and place the phone on the suction cup. The suction is strong and the phone is firmly attached.
We can see that the opening area is covered with protective foam padding and there is even a camera groove. It can keep your phone safe and scratch-free during operation.
The next step is to place the back down on the opening area. For different sizes of phones, we can adjust the left dial to attach the phone.
As the phone is attached, lower the upper body and suction cup on the phone.
Then we fasten the suction up and rotate the right dial to lift the display.
To prevent breaking the flex cable. Please stop rotating when the angle between the screen and back housing is 15 degrees.
Compared to the suction cup, the strength of the opening tool is easier to control for lifting the display, thus lowering the risk of breaking the display or flex cable. Other than the opening area, the tool features a pressing area. After the repair is complete, turn the dial to keep the screen or back cover firmly in place with the adhesive.
To sum up, the latest REFOX phone opening solution boasts high efficiency and safety. It is suitable for opening both android phones and Apple’s iPhone, keeping your daily repairs safe and efficient. Currently, there is free shipping for the opening tool kit on REWA Shop. Please feel free to leave a comment or contact our account managers if you are interested.
The basic tool for phone repair we can see commonly in the market is only for high-temperature soldering or heating the screen, such as the CPB heat mat.

The difference between RS30 Repair mobile phone heat pad and other repair mats is its Utility Patent which means it's practical and creative in the repair market.
There are many tools commonly used by mobile phone repair shops to fix or change cracked/broken mobile screens. For Example, adjustable screen fixing clip fixture, suction cup open hand tool, screen separator, etc. But most of them are only within a single function. So, we usually apply an opener on the screen first and then use another clamp fixture tool to press the screen. The old way we used to replace a new screen is using a rubber band to long-press it. However, it takes so much time and makes the customers wait unavoidably.
Today, we recommend you a brand new machine with both functions, opening and pressing. REFOX RS-50 is a Screen Opening and Press Clamp Fixture, which can efficiently remove and press mobile phones. It is available to dismantle various mobile phone screens, press different back covers, etc. We will tell you the features of a product as below:
High-quality aluminum alloy, durable to use
Adjustable design, compatible with all types of flat screen
Big size, strong suction, not easy to fall off
All-round EVA foam protecting from shock, safe and scratch-free
Four ball guide sets uniform force to make the frame glue fit better
Unique slot design, no damage to the frame
And its wide application on:
Remove the phone screen
Separate the back cover
