YCS Screen IC Solder Mask Repair Green Oil UV Stencil iPhone

The YCS Screen IC Solder Mask Repair Green Oil UV Stencil targets a problem every iPhone board technician knows well: the green protective layer around the screen IC pads tearing away during a display IC change. You lift the old chip with hot air, run solder wick across the pads, and the thin solder mask between them peels off with the old solder. Seat a new or reballed IC on that bare copper and the balls spread, bridge into each other, or touch the exposed ground plane, and the phone comes back with the same display problem, a hang on logo, or a completely dead phone. This stencil gives you a controlled way to rebuild that insulating layer before the new chip goes on, so your second attempt is not just a repeat of the first fault. YCS builds the stencil from actual iPhone logic boards at 1:1 scale, so every footprint matches the real screen IC pad layout of its model and you skip the guesswork of freehand green oil work with a toothpick or fine brush. One stainless steel sheet carries the screen IC footprints for the iPhone 11, 11 Pro, and 11 Pro Max, the full iPhone 12 lineup including the 12 Mini, all four iPhone 13 models, and the complete iPhone 14 and iPhone 15 families including the Plus and Pro Max variants. That range covers most iPhone display IC jobs that land on a Pakistani repair bench today, and you keep one tool in the drawer instead of a stack of separate plates. The stainless steel body resists bending and keeps its flatness after many rounds of alcohol cleaning, which matters more than most technicians expect, because a warped stencil lets oil creep under the edges and spoil pads you need to keep solderable. The working method fits straight into a normal board-level routine. Clean the screen IC area with flux remover and isopropyl alcohol until the pads look bright and level, then fix the board in your PCB holder under the microscope. Spread a thin, even coat of UV solder mask green oil over the pad area, press the matching footprint of the stencil flat on top, and align it against the surrounding components. Switch on your UV curing lamp and let it work through the hollow openings, which shape exactly where the oil hardens, then lift the stencil and wipe away the uncured oil with alcohol. You end up with a factory-style pattern: exposed pads ready for solder and a fresh insulating border between them, so the new IC sits level and every ball lands on its own pad. Keep the coat thin, because a heavy layer cures unevenly and can lift the chip slightly off the pads, and always check the result under magnification before you reflow. In the wider repair workflow this stencil sits between pad cleaning and IC installation, so it pairs naturally with tools you already own: a hot air station for chip removal, a soldering station with a flat tip for pad levelling, flux, solder wick, and the iPhone reballing stencil that matches your new screen IC. A stereo microscope makes alignment far easier, and a dedicated UV curing lamp gives a more even cure than a phone torch or a nail lamp held at an angle. When your shop starts taking more storage chip and BGA work, the matching YCS Font and NAND solder mask stencil carries the same method to BGA60 through BGA315 footprints. Shops that handle regular iPhone display IC jobs, refurbishing centers, and training institutes teaching board-level repair all get steady use from this tool, since it turns pad-damage recovery from a risky freehand job into a repeatable step. Treat the stencil well and it lasts for years: clean it with alcohol after every job, never scrape the openings with a metal pick, and store it flat inside its sleeve so the fine footprints stay straight. For technicians searching for a screen IC solder mask stencil price in Pakistan, this single sheet delivers five iPhone generations of coverage at the cost of one small consumable, and it saves boards that would otherwise end up as hardware fault returns or failed IC change jobs.
