  • How iPhone Aftermarket Battery BMS Boards Are Made

    How iPhone Aftermarket Battery BMS Boards Are Made

    When choosing an iPhone aftermarket battery, the BMS board (Battery Management System board) plays an important role in battery performance. So, what makes a third-party battery board reliable?

    In this article, REWA Lab takes you to explore how an iPhone aftermarket battery BMS board is manufactured, from bare PCB assembly and TI chip placement to firmware programming, functional testing, battery cell assembly, and final strict quality inspection.

    how iphone aftermarket battery bms boards made the crucial stages to

    What Is an iPhone Battery BMS Board?

    The BMS board is the control and protection system of a rechargeable battery, helping monitor the battery and protect it during charging and use.

    For an aftermarket iPhone battery, the BMS board works alongside the battery cell. While the cell stores the electrical energy, the BMS board manages and monitors important battery-related functions.

    Depending on the design, a battery BMS board can help with functions such as:

    • Battery voltage & current monitoring
    • Temperature-related protection
    • Overcharge & short-circuit protection
    • Battery data and state-of-charge estimation
    • Communication between the battery and device

    This is why two aftermarket batteries using cells with similar specifications can still have different real-world performance and reliability.

    Step 1: Bare PCB Preparation and SMT Assembly

    The manufacturing process starts with a bare PCB, which is the foundation of the BMS board. Before production begins, the factory receives bare PCBs that have already passed IQC inspection and loads them onto SMT feeder racks for automated component placement.

    Simply put:

    SMT stands for Surface Mount Technology. It is a manufacturing method that places tiny electronic components directly onto the surface of a circuit board.

    The basic process begins with solder paste printing. The PCB is positioned against a stencil, and solder paste is applied to precisely defined positions on the board.

    Automated SMT squeegee applying gray solder paste over a stencil onto a BMS circuit board

    Infrared marking helps identify the positions of the solder pads, while an SPI system checks the printed solder paste to identify issues such as:

    • Solder paste offset
    • Insufficient solder paste
    • Excessive solder paste
    • Solder bridging
    A Sinic-Tek 3D SPI machine monitor displaying a panel inspection layout for solder paste quality control

    This inspection is important because inaccurate solder paste printing can affect the quality of component soldering later in the process.

    Step 2: High-Speed Component Placement

    After solder paste printing, SMT machines precisely place resistors, capacitors, inductors, and other components onto their designated positions on the PCB.

    High-speed nozzles pick up individual components and place them according to the programmed layout of the PCB. Infrared reference marks help the equipment maintain accurate positioning.

    Automated SMT pick-and-place nozzles positioned above a circuit board

    For battery BMS boards, precise component placement is essential because the board contains many small components within a compact design.

    Step 3: Installing the TI Battery Management Chip

    One of the key components on the board is the TI chip. As a key control component of the battery management system, it serves as the “brain” of the BMS, helping monitor and manage battery performance.

    The REWA Selected battery board uses a custom TI chip with an Impedance Track algorithm.

    Simply put:

    The algorithm helps the battery system estimate the battery’s remaining capacity more accurately by tracking the battery’s electrical characteristics, including impedance.

    Battery impedance changes as the battery operates and ages. Monitoring these characteristics allows the battery management system to make more informed estimates of the battery’s actual state.

    Step 4: Reflow Soldering and AOI Inspection

    Once the components have been placed, the PCB enters the reflow soldering process. The board passes through a controlled thermal profile consisting of preheat, soak, reflow, and cooling stages, permanently connecting the components to the PCB.

    Afterward, the board undergoes AOI (Automated Optical Inspection) scanning.

    Simply put:

    AOI uses cameras to inspect the board automatically and compare the soldered components and joints against predefined standards or a golden sample.

    Automated optical inspection machine head scanning circuit boards under bright light on an assembly line

    If the system identifies an NG (No Good) board, the board is manually reviewed to separate real defects from false positives.

    Step 5: Underfill Reinforces BGA Component Connections

    After solder inspection, automated equipment applies underfill along the edges of BGA components before the adhesive is cured in an oven, which helps provide additional mechanical support.

    For battery BMS boards, this stage can improve resistance to physical shock and vibration, helping strengthen the connection between the component and PCB during handling and use.

    Step 6: Firmware Programming and Flex Cable Bonding

    The completed PCB is programmed with firmware before its flex cable is bonded using controlled heat and pressure. To put it simply, firmware is the embedded software that controls how the hardware operates.

    How do the controlled heat and pressure achieve?

    Through a hot-bar bonding process, the controlled heat and pressure are used to bond the flex cable to the PCB.

    bonding flex cable

    After bonding, the flex cable connection is verified through FCT (Functional Circuit Test) to check whether the assembled board actually functions as intended.

    Step 7: Battery Cell and BMS Board Assembly

    In the assembly stage, the factory first uses capacity-matched cells. The cell tabs are then cut before the cell is connected to the BMS board through fiber laser spot welding.

    Why Is Weld Quality Important?

    The weld connects the battery cell to the BMS board, so the quality of this connection directly affects the electrical and mechanical integrity of the battery pack.

    Automated spot welding equipment connecting a battery cell to a BMS board held in an assembly fixture

    After welding, each weld joint is checked for durability. The battery pack then receives insulation tape and a rubber casing as part of the assembly process, helping provide both electrical insulation and physical protection.

    Step 8: Final Quality Inspection and Battery Testing

    Manufacturing does not end when the battery pack is assembled. A strict final quality inspection is performed before the battery is considered ready for shipment.

    After final inspection, the battery enters a resting period, during which parameters such as voltage and internal resistance are monitored.

    Monitoring voltage and internal resistance during the resting period provides additional data for quality control.

    Why the BMS Board Matters for Aftermarket iPhone Batteries

    The BMS board is often hidden inside the battery, so it is easy to overlook when comparing aftermarket batteries. However, its design and manufacturing quality can influence important aspects of battery operation.

    A reliable third-party battery requires more than simply selecting a battery cell with the right capacity. The cell, BMS board, firmware, electrical connections, protection circuitry, manufacturing process and strict quality test before shipping all work together.

    For distributors, refurbishing facilities, and repair shops, this means that battery evaluation should go beyond looking at the printed capacity or external appearance.

    Frequently Asked Questions

    What is the difference between a battery cell and a BMS board?

    The battery cell is the component that stores electrical energy. The BMS board is the electronic management and protection system that monitors the cell and controls related battery functions.

    What is a TI chip in a battery BMS board?

    TI refers to Texas Instruments, a semiconductor manufacturer whose battery-management ICs are used in various battery applications. In the REWA Selected battery board shown in the video, a custom TI chip with an Impedance Track algorithm is used to support accurate battery monitoring and gauge estimation.

    Why are SPI and AOI inspections important?

    SPI checks the accuracy of solder paste printing before components are soldered, while AOI uses cameras to inspect the assembled PCB and solder joints afterward. These inspections help identify manufacturing issues at different stages of PCB production.

    Why does REWA test battery voltage and internal resistance after assembly?

    Voltage and internal resistance provide important information about the electrical condition of a battery pack. Monitoring these parameters after assembly and during the resting period adds another layer of quality control before the battery is shipped.

    Why measure internal resistance during final quality inspection?

    Internal resistance is one of the important electrical characteristics of a battery. Lower internal resistance generally means less electrical energy is lost inside the battery when current flows, although battery performance cannot be judged by this parameter alone.

    Conclusion

    An aftermarket iPhone battery is more than a battery cell. Behind the finished product is a BMS board that integrates electronic components, battery-management technology, protection functions, firmware, and flex-cable connections.

    From a bare PCB to a complete battery pack, every stage can contribute to the consistency and reliability of the finished battery.

    • Unstable Product Quality: Poor sourcing leads to after-sales issues and operational disruptions.
    • Lack of Technical Expertise: Many refurbishers struggle with using purchased parts and tools effectively.
    • After-Sales Concerns: Ineffective support from suppliers leaves refurbishers facing unresolved problems.
    • Complex Supply Chains: Managing multiple suppliers can lead to inefficiencies and extended turnover cycles.

  • iPhone 16 Pro Swap Parts: Face ID Remains Functional

    iPhone 16 Pro Swap Parts: Face ID Remains Functional

    With the introduction of iPhone 16 and iOS 18, Apple has refined how parts swaps are handled with the new ‘Parts & Service’ and ‘Repair Assistant’ features. In this article, REWA Lab tests these updates by swapping parts between two iPhone 16 Pro devices. We discovered not only that Face ID remains fully functional after being replaced and reconfigured, but also that the phone’s enclosure now generates a repair history and requires reconfiguration after a swap.

    We recommend to watch video first:

    Back Glass Swap: New Part Pairing

    In previous iPhones, the back glass wasn’t tied to the phone’s system. However, when we swapped the back glass on the iPhone 16 Pro, a ‘Parts & Service History’ notice appeared, indicating the detection of a new back glass. After configuration, the message disappeared.

    Figure 1. A new back glass was detected

    Rear Camera Swap: Calibration Needed

    Swapping the rear cameras between two phones triggered the ‘Parts & Service History’ message. Unlike other parts, the rear camera required calibration via the Repair Assistant, which involved moving the phone as prompted. It is important to note that calibrating the camera is just one step in running the Repair Assistant. In fact, after replacing the camera, the phone can still take photos or record videos normally, even without running the Repair Assistant calibration. Furthermore, after completing the process, the system marked the camera as ‘Used’ in the parts history.

    Face ID Assembly Swap: A Significant Improvement

    A significant change on the iPhone 16 Pro is the ability to swap the Face ID assembly and retain functionality. After swapping the Face ID and running the Repair Assistant, the system fully restored Face ID functionality. Although it was recorded as a ‘Used’ part in the system, this is a major improvement, as Face ID was previously tied to the motherboard and would not work after replacement in older iPhone models.

    Battery Swap: Effects on Health Data

    After swapping the battery, the system labeled it as an ‘Unknown Part,’ and battery health data was disabled. Additionally, the ‘Parts & Service History’ indicated the battery required configuration. Once configured, the ‘Unknown Part’ message disappeared, and battery health data returned, with the system marking the battery as a ‘Used’ component.

    Screen Swap: True Tone Can Be Restored

    Swapping the screens caused the True Tone feature to disappear initially. After configuring the system, True Tone was restored, and the screen was labeled as ‘Used’ in the parts history. This emphasizes the importance of system configuration after screen replacements to maintain features like True Tone.

    Motherboard Swap: Enclosure Needs Configuration

    To further test the system, we swapped the motherboards of the two phones. Interestingly, the major parts functioned normally, and there were no repair notices for these parts in the ‘Parts & Service History.’ However, a new notification prompted us to configure the enclosure, and the system required rear camera recalibration again.

    Parts History: An Ongoing Investigation

    Even after swapping back the native parts, the system continued to display their repair history, though it verified them as genuine. This suggests that once parts are replaced, the system may permanently record their history. However, further verification is needed, and REWA Lab will continue to explore this behavior in future tests.

    Conclusion: Face ID and Other Swap Parts in iPhone 16 Pro

    Our tests reveal that iPhone 16 Pro, with iOS 18’s Repair Assistant, allows for greater flexibility when swapping parts, particularly with Face ID, which can now be replaced without losing functionality. The ‘Parts & Service’ feature ensures accurate tracking of swapped components, and we will continue to explore how third-party parts interact with this system in future tests.
