Mechanic Z10 (0.4mm) Solder Ball 10000 Pieces

Every technician who has lifted a CPU from a dead phone knows the job only finishes when the chip sits back down with clean, even joints, and that is exactly where the Mechanic Z10 (0.4mm) Solder Ball 10000 Pieces earns its place on your repair bench. Mechanic sells these balls under its XZ10 leaded series, and each bottle holds 10,000 balls in a Sn63/Pb37 alloy, meaning 63 percent tin and 37 percent lead. That eutectic mix melts sharply at 183°C instead of passing through a soft paste stage, so every ball on the chip collapses into a joint at the same moment and you avoid the half-melted, uneven rows that leave a phone hanging on logo or restarting after a board repair. The 0.4mm diameter matches a 0.4mm reballing stencil, and the balls come out of the bottle with high sphericity and a clean surface, so they roll into stencil holes without clumping together or leaving empty pads. In a typical Pakistani workshop, reballing comes up daily: a Qualcomm or MediaTek CPU with a cracked joint after a drop, an eMMC or UFS chip that needs removal for data work or replacement, a PMIC swap on a no-power board, or a charging IC change on a phone with a charging issue. Each of these jobs follows the same path. You remove the chip with your hot air station, clean the old solder off the pads with a soldering iron and desoldering wick, apply a thin layer of flux, place the chip in a reballing kit or under a matching stencil, pour a small amount of balls over the holes, and brush the extras back into the bottle. You then heat the stencil evenly until the balls melt and form bumps, lift the stencil, clean off the flux, and inspect every row under a microscope before you place the chip back on the board. The quality of the balls decides how much of that process goes right the first time. Balls with poor roundness jam in the stencil, oxidised balls refuse to wet the pad, and mixed sizes leave some joints shorter than others, which later shows up as a network issue, a display problem, or a phone that goes dead again after a few days. The Mechanic XZ10 line targets those failure points with high purity, consistent sizing, and good resistance to oxidation and thermal fatigue, so the joints you build hold up through normal phone heating cycles. Leaded alloy also stays forgiving for bench rework because it flows at a lower temperature than lead-free solder, which reduces the heat load on the board, nearby capacitors, and underfill. Mechanic keeps separate XZW10 bottles for lead-free work, so pick the XZ10 when your process uses leaded solder and a lower rework temperature. The 10,000-piece count gives real value for a busy shop. A single chip takes anywhere from dozens to several hundred balls, and because you recover the unused balls after each pour, one bottle keeps a technician stocked across a long run of CPU, memory, and IC jobs. Keep the bottle closed and away from moisture between uses so the balls stay clean and free-flowing. For best results, pair these balls with a 0.4mm stencil from a reballing kit, a quality no-clean flux, a PCB holder to keep the board steady, and a stereo microscope for inspection. If you are building out your board-level bench, look at the rest of the rework chain as well: hot air stations for chip removal, soldering stations for pad cleaning, multimeters and test boxes to confirm the fault before and after the repair, and ISP pinout tools, eMMC programmers, and UFS adapters for memory work where the chip needs reading or writing off the board. Technicians moving up from basic IC change jobs to full CPU reballing quickly learn that steady consumables make as much difference as expensive machines, and this bottle covers one of the most frequently used consumables on any rework table. Order the Mechanic Z10 (0.4mm) Solder Ball 10000 Pieces from KB GSM Store for delivery across Pakistan, including Lahore, Karachi, and Islamabad, and keep your reballing stock ready for the next dead phone that lands on your bench.
