Working on an iPhone motherboard without a proper holding fixture almost always ends in the same problem — the board shifts under hot air, solder joints crack from uneven pressure, or a chip lands slightly off its pads during reballing. The MiJing A22+ solves this by giving your repair bench a dedicated clamping platform built specifically around iPhone board geometry from the 5S generation through the XR. The fixture uses an aluminum-copper alloy body, which holds up better under repeated hot air exposure than plastic-based holders that warp or discolor after a few reballing sessions. At 120 x 120 x 4mm, it stays compact enough to sit next to your hot air station and microscope without eating up bench space, yet the clamping area is wide enough to accommodate full-size iPhone Plus boards. What sets the A22+ apart from basic single-purpose holders is its dual-zone design. The main clamping area uses a metal sliding buckle and dovetail clasp system to lock the board rigidly in place — ideal for CPU reballing, NAND chip removal, and any operation where the board absolutely cannot move mid-repair. A secondary rubber maintenance zone gives you a cushioned surface for tasks like fingerprint sensor alignment work or board flexing during component testing, where a completely rigid clamp would put unwanted stress on the board. For technicians running a busy repair counter, board prep time matters. The A22+'s buckle-and-clasp mechanism seats a board in seconds rather than requiring you to fiddle with screws or adjustable arms. Once locked, the board stays put through extended hot air sessions, so you can work on IC change jobs, jumper repairs, and dead-after-flash boards without babysitting board position every time you move the hot air nozzle. This fixture covers a wide compatibility range in a single tool — iPhone 5S, 5C, 6, 6 Plus, 6S, 6S Plus, 7, 7 Plus, 8, 8 Plus, and XR boards all fit the same holder, meaning you don't need a separate fixture for every model generation coming through your shop. That range makes the A22+ a practical bench staple for service centers handling mixed iPhone repair volume rather than a single-device specialist tool. In day-to-day GSM shop use, this fixture shows up most often during dead phone diagnosis where a board needs to be pulled and tested outside the chassis, during CPU or NAND IC reballing where board stability determines whether the reball succeeds, and during general board cleaning and inspection under a microscope. Its high temperature resistance means it holds shape through direct hot air gun contact, so it doesn't need to be swapped out or cooled between back-to-back jobs. For a workshop doing motherboard-level work regularly, a fixture like the A22+ pays for itself quickly — fewer damaged pads from board slippage, faster board prep between jobs, and one tool covering nine iPhone generations instead of a shelf full of model-specific holders.
