    Frequently Asked Questions

    What is a CNC board for iPhone 13 Pro Max?
    A CNC board is a blank donor board. The iPhone 13 Pro Max uses a stacked "sandwich" logic board. It has an upper half and a lower half joined by connectors. This product is the upper half. It arrives with no chips installed. A technician removes working chips from your original board. They then solder those chips onto this blank board.
    Which chips can I transfer to this board?
    Four chips can be transferred. The CPU (Application Processor) carries your phone's serial number and IMEI. The baseband chip controls cellular and call functions. The NAND flash chip holds your 128GB of storage data. The EEPROM chip stores boot and hardware calibration data. All four move from your old board to this blank one.
    Will this fix an iCloud locked iPhone 13 Pro Max?
    Yes, for the right scenario. The iCloud lock is tied to the CPU chip — not the board itself. A technician removes your CPU from the iCloud-locked phone. They solder it onto this clean blank board. The resulting board will pass activation because the CPU is legitimately linked to the Apple ID. This process requires advanced microsolder skills. Bring your phone to our Brisbane shop for this service.
    Do chips come pre-installed on this board?
    No. This is a completely blank donor board. No chips are included. You must supply the chips yourself. They come from a donor iPhone 13 Pro Max 128GB. The blank board gives you a clean platform to solder your working chips onto.
    What tools are needed for this swap?
    This is advanced board-level repair. You need a hot air rework station for chip removal. A soldering iron with fine tips is required. Flux, BGA solder balls and a reballing stencil are essential. A microscope helps with accurate chip placement. This work is not suitable for home repair. Professional training and equipment are required.
    What is the difference between the upper and lower board?
    The iPhone 13 Pro Max uses a split two-layer logic board design. The upper board contains the CPU, baseband, EEPROM and NAND chips. The lower board handles other functions like charging and power management. This product is the upper half only. If you need the lower board, contact us for availability.
    Will this work with a 256GB or 512GB iPhone 13 Pro Max?
    No. This board is configured for 128GB only. Higher storage models use different NAND chip configurations. Using the wrong board will cause boot and activation errors. Check that your original phone is 128GB before purchasing. Settings → General → About → Storage will show you the capacity.
    How do I confirm my iPhone 13 Pro Max model number?
    Check the back of your iPhone 13 Pro Max. The model number is printed in small text near the bottom. It starts with "Model" and shows a letter-number code like A2643. You can also check Settings → General → About → Model Number. Compatible models are A2643, A2484, A2641, A2644 and A2645.
    Can I get chip swap service done at your Brisbane shop?
    Yes. Bring your phone to our Forest Lake workshop. Our technicians perform iPhone board-level repairs. We have the hot air stations, microscopes and tools needed for chip swaps. Contact us first to discuss your repair and get a quote. Call 0480 039 913 or visit Shop 3a, 152 Woogaroo St, Forest Lake QLD 4078.
    Does this board carry a warranty?
    No warranty is included with blank CNC boards. The board is a bare donor substrate. Its performance depends entirely on the chips your technician installs. A chip damaged during removal or reballing is not covered. Always test chips before and after transfer. Contact us if you have questions before buying.
