Qianli Bumblebee Stencil (QS148) For Phone 6S-12 Screen IC

Qianli QS148 Bumblebee Stencil for iPhone 6S to 12 Screen IC Reballing The Qianli Bumblebee Stencil (QS148) For Phone 6S-12 Screen IC handles one job on your bench: reballing the display IC on iPhone boards from the 6S generation up to the 12 generation. When a screen IC lifts or fails, you cannot refit it without fresh solder balls, and freehand balling wastes time and damages pads. This stencil gives you a fixed pattern, so every ball lands where the IC expects it. It slots straight into a normal microsoldering routine next to your hot air station and soldering iron.Where QS148 Fits in Your Repair Workflow You reach for this stencil after diagnosis, not before. A hardware fault on the display side usually shows up as a black screen with the phone still alive, a flickering panel, or a touch problem that no replacement screen fixes. Once you confirm the screen IC is the culprit, you remove it, clean the board pads, and reball the chip before you refit it. QS148 covers the reballing stage of that job. Because the Bumblebee series targets iPhone display ICs, you spend less time hunting for a matching pattern and more time finishing the repair.Reballing the Screen IC Step by Step Start by checking that the stencil pattern matches your IC under the microscope. Apply flux, remove the old solder from the chip with your iron, and clean the pads until they sit flat and bright. Hold the IC steady, align it with the stencil, and work your solder paste across the openings. Heat the stencil with your hot air station until the paste forms balls, then let everything cool before you lift the stencil away. Check each ball under magnification. If you see a missing or merged ball, clean the chip and repeat. Rushed heating is the usual cause of bridging, so take your time on this step.Who Should Buy It and What to Pair It With Repair shops that run daily iPhone display jobs get the most from QS148. Technicians who offer IC-level service, rather than only screen swaps, can handle boot-time display faults in-house instead of sending boards out. Pair the stencil with a good hot air station, a temperature-controlled soldering station, a microscope, a reballing kit, and a PCB holder to keep the board steady while you work. If your customers bring newer iPhones, Qianli also sells Bumblebee stencils for later series, which gives you a clear upgrade path as your workload grows.
