    ⚙️ What This Blank Board Does

    ⚙️

    CPU / AP Chip Swap

    Move the Apple A14 Bionic Application Processor onto this clean board. The CPU carries your iPhone's serial number, IMEI and iCloud pairing.

    📡

    Baseband Transfer

    Transfer the baseband chip that controls 5G/LTE cellular, voice calls, GPS and modem-side network functions.

    💾

    128GB NAND Flash Swap

    Move the 128GB NAND storage chip. Keeps user data, photos and apps paired to the original CPU — no data wipe required.

    🔩

    EEPROM Transfer

    Swap the EEPROM memory chip that stores boot configuration, calibration data and board-pairing information.

    🧩

    Blank CNC Donor

    Clean CNC-machined PCB substrate with no chips installed — ready to receive your working components from the donor iPhone.

    🔧

    OEM Form Factor

    Machined to exact iPhone 12 Pro Max dimensions. Upper half of the stacked sandwich design — connector positions match factory.

    💡 When Is This Board Used?

    ☁️ iCloud Locked iPhone Recovery

    iCloud activation lock is bonded to the CPU chip — not the board. Removing the original CPU and reballing it onto a clean blank board lets the device pass activation legitimately. The chip stays paired to its original Apple ID.

    💧 Water Damage Recovery

    When liquid corrodes the board's traces but the chips themselves are still electrically intact, transferring the working chips onto this clean substrate restores the device — no chip replacement, no data loss.

    ⚡ Board-Level Trace Faults

    Broken vias, lifted pads, shorted lines or burned traces on the original board mean the chips can't talk to each other. Move the still-working chips to this blank donor board and the device boots again.

    🛠️ Repair Workshop Stock

    Stocking blank CNC boards lets shops accept iCloud-unlock and water-damage jobs the same day a customer walks in. Faster turnaround, more repair revenue, fewer rejected jobs.

    📚 Microsolder Training Schools

    Practice BGA reballing, chip removal and reflow technique on real iPhone 12 Pro Max substrates. Ideal for repair-school students learning board-level workflows on current Apple silicon.

    🔄 Donor Phone Conversion

    Salvage the chips from a smashed-screen donor phone and rehost them on a clean blank board to rebuild a fully working device — common in refurb workflows and parts-recycling shops.

    Frequently Asked Questions

    What is a CNC blank donor board for the iPhone 12 Pro Max?+
    A CNC blank donor board is a clean, machined PCB substrate. The iPhone 12 Pro Max uses a stacked sandwich logic board — an upper half and a lower half joined by board-to-board connectors. This product is the upper half. It arrives with no chips installed. A microsolder technician removes working chips from a damaged original board and reballs them onto this clean substrate.
    Which chips can I transfer onto this iPhone 12 Pro Max board?+
    Four key chips can be transferred. The CPU (Apple A14 Bionic Application Processor) carries the iPhone's serial number and IMEI. The baseband chip controls 5G/LTE cellular and voice calls. The 128GB NAND flash chip stores user data. The EEPROM chip holds boot and calibration data. All four move from the original board to this blank substrate.
    Will this fix an iCloud locked iPhone 12 Pro Max?+
    Yes — for the right scenario. iCloud activation lock is bonded to the CPU chip itself, not the board. Removing the original CPU and reballing it onto this clean blank board lets the device pass activation legitimately because the chip stays paired to its original Apple ID. The work requires advanced microsolder skills. Bring the phone to our Forest Lake workshop if you'd like our techs to handle the swap.
    Are any chips pre-installed on this CNC board?+
    No. This is a completely blank donor board. No chips are included — no CPU, no baseband, no NAND, no EEPROM. You must supply the working chips yourself, salvaged from a donor iPhone 12 Pro Max 128GB. The blank board gives you a clean substrate to reball them onto.
    What tools are needed for the chip swap?+
    This is advanced board-level repair. You need a hot air rework station with fine nozzles for chip removal. A soldering iron with micro-tips is essential. Flux, low-melt solder, BGA solder balls and a reballing stencil matched to the iPhone 12 Pro Max BGA pitch are required. A stereo microscope helps with accurate chip placement. None of this is suitable for home repair.
    What's the difference between the upper and lower board?+
    The iPhone 12 Pro Max uses a two-layer stacked sandwich logic-board design. The upper half holds the CPU, baseband, EEPROM and NAND chips — the brain of the phone. The lower half handles charging, power management, audio and other peripheral functions. This product is the upper half only. Contact us on 0480 039 913 if you need a lower-board donor.
    Will this work with a 256GB or 512GB iPhone 12 Pro Max?+
    No. This board is configured for 128GB only. Higher-capacity models use different NAND flash chip configurations and pad layouts. Using the wrong-capacity board will cause boot failures and activation errors. Check capacity in Settings → General → About → Storage on the donor phone before purchasing.
    How do I check my iPhone 12 Pro Max model number?+
    Look on the back of the iPhone — the model number is etched in small text near the bottom and starts with "Model A" followed by four digits like A2411. You can also check Settings → General → About → Model Number. Compatible numbers for this board are A2411 (international/AU/EU), A2342 (US), A2410 (China dual SIM) and A2412 (Japan).
    Can JPC Mobile do the chip swap service for me?+
    Yes. Bring the phone to our Forest Lake workshop. Our technicians perform iPhone board-level repairs in-house using hot air stations, microscopes and OEM-pitch reballing stencils. Contact us first to discuss your situation and get a quote — call 0480 039 913 or visit Shop 3A, 152 Woogaroo St, Forest Lake QLD 4078.
    Does this CNC board come with a warranty?+
    No warranty is included with blank CNC donor boards. The board is a bare substrate — its working performance depends entirely on the chips your technician installs and the quality of the reball/reflow work. A chip damaged during removal or reflow is not covered. We recommend testing chip continuity before and after transfer. Contact us with any pre-purchase questions.
