iPhone 14 Pro CNC Donor Board

The iPhone 14 Pro board is one of the densest Apple has made, and when it's damaged beyond trace repair, the options narrow quickly. This CNC-machined donor board for the 14 Pro lets you rebuild instead of giving up on the phone or its data.

It's available as an upper layer without NAND, or a lower layer in US or EU versions. Treat it as a donor PCB, not a drop-in motherboard.

Reasons to rebuild on a donor PCB

• Shorts inside the layers that can't be isolated.

• Severe corrosion around the processor area.

• Board warped by excessive heat.

• Traces lost during earlier repair attempts.

Equipment and planning

Expect to need a stereo microscope, a good preheater, fine hot air nozzles and stencils for each chip you move. Study the board view and plan the order of transfers before you begin.

Match the lower-layer region to the phone. After rejoining, power the board from a bench supply and watch the current before connecting a battery. A slow, steady rise to a normal boot pattern is what you want; any sudden jump means stopping and checking the last transfer before going further.
