XZZ Motherboard Layered Test Fixture for iPhone 14 Series

iPhone 14 boards keep the stacked sandwich design, so a fault on one layer can hide behind the other. This XZZ layered fixture lets you seat and test each layer on its own while you narrow down the problem.

The fixture from XZZ (Xinzhizao) is listed for the iPhone 14, 14 Plus, 14 Pro and 14 Pro Max. It has a flame-retardant, high-temperature and corrosion-resistant needle board with customized gold-plated spring probes, and the listing claims low detection deviation and long probe life.

When it earns its place

• A separated iPhone 14 board that won't boot.

• Finding which layer carries a short or a failed component.

• Testing a repair before rejoining the layers.

• Moving a good layer to a donor board.

Fit and handling

The 14 and 14 Plus use a different board design from the 14 Pro and 14 Pro Max, so check in the photos how the fixture handles each model before relying on it for both.

It measures 116 × 63 × 17 mm and weighs about 143 g. Keep the probes clean with a soft brush and isopropyl alcohol, and cover the fixture between jobs.
