Which iPhones use the A17?

It is the application processor in iPhone 15 Pro generation. Confirm the chip marking on the board before ordering — a stencil cut for one footprint will not align on another.

Do I need the Z21 platform as well?

Yes, or an equivalent fixture. The stencil sets the ball positions; the platform holds the chip square underneath it so the stencil lies flat.

A reballing stencil cut for the Apple A17 CPU footprint, used with the Z21 platform.

The A17 is the application processor in iPhone 15 Pro generation, and it is one of the least forgiving chips on the board to reball — the pitch is fine and the array is large, so a stencil cut for the exact footprint is the difference between a reball that reflows first time and one you chase for an hour.

Key features

Cut for the Apple A17 footprint specifically
Places the entire array in one squeegee pass
Pairs with the Mijing Z21 reballing platform

What this is used for

Reballing an Apple CPU after removal
Rebuilding the ball array on a reclaimed chip
Repairing lifted pads under the CPU

Who it's for

Micro-soldering technicians doing CPU-level iPhone repair.
