Middle layer reballing on modern iPhone boards punishes a fixture that shifts. A stencil that drifts half a millimeter during reflow turns a clean chip repair into a bridged, dead-after-flash board. The RELIFE RL-601T solves this with a universal base and swappable stencil system that locks position through the whole reflow cycle, covering everything from iPhone X up to the 15 Series.
The base plate carries three embedded high-temperature magnets. They hold the steel stencil flat against the module clamp so it can't move while you're feeding solder or running your hot air gun over the board. Magnetic strength doesn't drop off under heat the way spring-clip fixtures do, which matters when you're running back-to-back jobs and the base is still warm from the last board.
You get one base, 5 module clamps, and 17 steel stencils in the set — 22 configurations across the model range, so you're not buying a new jig every time a new iPhone comes out. Each stencil is cut from 0.12mm steel, with round and square hole positions matched to the original factory layout for that board revision. This hole precision keeps solder balls uniform — inconsistent holes cause balls to jam in the mesh or come out flattened, and that shows up later as a boot loop issue or a board that dies again a week after the repair.
On the bench, the sequence is simple. You seat the module clamp for the iPhone you're working on, drop in the matching stencil, and the magnets pull everything into position on their own. Apply your solder across the mesh, run your hot air station at the profile your solder needs, then lift the stencil once the balls have formed. Since the base and clamps carry over across every model, you're not resetting your setup each time a different board comes in — you just change the stencil.
This platform sits in the reballing and middle-layer repair stage of your workflow — after diagnostics has isolated a chip-level fault, before you move to full IC replacement or CPU-level rework. It pairs naturally with a hot air rework station, PCB holders to secure the board, and a microscope to check ball uniformity before reflow.
For a repair shop or service center handling a steady flow of iPhone motherboard jobs, the real saving is bench space and setup time. One base replaces a drawer full of model-specific jigs, and the stencil swap takes seconds instead of hunting for the right fixture between repairs. The steel construction holds up to repeated heat exposure without warping, so the hole geometry stays accurate job after job — which is what actually determines whether your reballed chip survives more than a few charge cycles.
