Qianli Bumblebee Stencil (QS188)

Qianli Bumblebee Stencil (QS188) for Xiaomi 15 Board Reballing Reballing decides whether an IC change karna job ends with a working board or a second teardown. The Qianli Bumblebee Stencil (QS188) targets the Xiaomi 15, so you work with a stencil matched to one model instead of forcing a universal pattern onto a board it was never cut for. A model-specific stencil also saves you time, because you skip the trial and error of testing patterns against the pads. Xiaomi boards reach Pakistani benches with dead phone, charging issue, and hardware fault complaints, and many of those jobs end at the same step: fresh balls under a lifted IC. This page shows you where the stencil fits, how you handle it, and what you confirm before you order.Where the QS188 fits in your Xiaomi 15 workflow You reach for this stencil after diagnostics, not before. First you confirm the fault with your multimeter and microscope, then you decide whether the IC needs a reflow or a full replacement. When you lift the IC with your hot air station, the pads underneath need cleaning, and the stencil takes over from there. You align its openings with the pads, apply solder paste or place balls, and heat the area until the balls form. Pad cleanliness decides the result, so spend your time on cleaning, not only on heating. This sequence belongs to hardware repair. A stencil does not fix an FRP lock, a pattern unlock, or a boot loop issue caused by software, so you flash first and trace the board only when a Xiaomi 15 stays dead after flash or hang on logo persists. That order saves you from lifting good ICs for faults that a box chalana session would have solved.Handling the QS188 on your repair bench Qianli builds Bumblebee stencils model by model, so the QS188 belongs to the Xiaomi 15 and you should not borrow it for other Xiaomi phones. The same brand lists the QS152 for the Xiaomi 14, for example, which shows how tightly each stencil follows its own board. Clamp the board in a PCB holder before you start, because a stencil that shifts mid-job ruins the ball pattern. Apply flux, set the stencil flat against the pads, and keep your hot air station at a controlled temperature so you protect the neighbouring components. Let the board cool before you lift the stencil, then check the new balls under your microscope. Clean the stencil with flux remover after every job and store it flat. If your shop handles many brands, label each stencil by model number, so you grab the QS188 in seconds instead of testing five.What to confirm before you order for your shop Check the model first: the QS188 supports the Xiaomi 15, so confirm your customer’s phone is exactly that model before you buy. Compare the stencil openings with the IC footprint under your microscope before you heat anything, because a stencil only helps when its pattern matches the part on your board. You also need the basics around it: a hot air station, flux, solder paste or balls, and a steady PCB holder. Keep the stencil away from bending and heat in storage, since a warped stencil gives you uneven balls. If you reball many different phones, add a multi-function stencil such as the Qianli Bumblebee Stencil (QS65) as your upgrade path, and browse our Reballing Kits, Hot Air Stations, and Microscopes categories to complete your bench.
