Built for Mid-Layer Tin Planting on the iPhone 14 Series
The Qianli 4-in-1 Magnetic Middle Frame BGA Reballing Platform for iPhone 14 / 14 Plus / 14Pro / 14Pro Max is a soldering tool made for one job: planting fresh tin balls on the middle layer of 14 series motherboards. Your board sits on the base while the magnetic middle-frame stencil locks down on top. Four models share one platform, so you do not need a separate fixture for each handset. Qianli lists it as suitable for the iPhone 14 series.
Precise Motherboard Positioning
Most reballing failures start with alignment. A board that shifts even slightly under the stencil puts tin balls off the pads, and those balls bridge or never seat. This platform holds the motherboard in a set position so the stencil openings line up with the pads each time. Qianli specifically calls out precise positioning for the motherboard, which matters most when you work on a board that a previous tech already opened. Start with a stable board and your paste goes where you planned.
Magnetic Pressing for Clean Tin Balls
The strong magnet inside the platform pulls the stencil flat against the board. A flat stencil leaves less gap for paste to creep under, and it stays put while you spread the solder paste and lift the frame off. Qianli describes this as strong magnetic pressing with no bulge, which means the stencil sits evenly rather than rising at the edges. Keep the stencil flat during the whole process, and your tin balls come out more uniform across the layer.
Where It Fits in Your Reballing Workflow
On the bench, the sequence runs like this. Seat the motherboard in the base, align the middle frame over it, and spread low-temperature solder paste across the stencil. Remove the frame, then heat the paste with your hot air station until it melts. Keep the stencil in the platform while you do this step, and avoid focusing heat straight onto the stencil. Use a microscope to check the pads before and after planting, and keep your reballing kits and PCB holders within reach so the board stays secure through every step. This platform works best as one stage in a full mid-layer repair setup, not as a standalone fix for every dead phone.
