XZZ Motherboard Layered Test Fixture for iPhone 16 Series

Unlike many fixture listings, this one explains how the parts go together, which helps if you've never used a layered fixture before. The XZZ fixture for the iPhone 16 series holds the boards and a test pinboard in a frame closed with side buckles.

The fixture from XZZ (Xinzhizao) is listed for the iPhone 16, 16 Plus, 16 Pro and 16 Pro Max. It measures 128 × 68 × 18 mm and weighs about 189 g.

When it's needed

• A separated iPhone 16 board that fails to boot.

• Isolating a short to one layer.

• Testing a repair before the sandwich is rejoined.

• Data recovery from a damaged iPhone 16 board.

Assembly, per the listing

Place the radio frequency board in the frame, then lay the layered pinboard on top. Seat the logic board on the test pinboard, bring everything together and fasten the buckles on both sides.

Check that every board sits flat before closing the buckles; an uneven layer leaves some probes without contact. Clean the pads first, power up with a conservative current limit, and open the buckles evenly when you're done to avoid flexing the boards.
