Relife RL-093B 0.3mm Chip Heat Sink Copper Sheet

When you are working on a hang on logo board or pulling an IC for reballing, heat control decides whether the job goes clean or turns into a bigger headache — the Relife RL-093B 0.3mm Chip Heat Sink Copper Sheet exists to solve exactly that problem on your repair bench. Made from pure copper, this sheet carries high thermal conductivity, so it draws heat away from the target chip quickly and spreads it evenly instead of letting it build up in one spot; that uniform heat diffusion is what protects the solder joints on neighboring ICs from melting while you run hot air over the chip you actually need to remove. At 0.3mm thickness, it sits in the middle of Relife's RL-093 series between the thinner 0.1mm RL-093A and the thicker 0.5mm RL-093C, giving you a balance of heat absorption and flexibility that works well for standard CPU and GPU chip cooling tasks on modern smartphone mainboards. You lay the sheet over the chip before applying hot air during CPU or IC repair, and it acts as a barrier that shields the surrounding board from the same heat that is loosening the solder underneath your target component, which matters a lot when you are working close to other sensitive parts like power management ICs or baseband chips. The copper also carries strong corrosion resistance, so it does not oxidize or degrade quickly even with repeated use across multiple boards, which means one pack lasts you through a real workload of boot loop issue repairs, dead after flash recoveries, and routine chip reballing without needing constant replacement. Surface quality is something technicians notice fast, and this sheet has a smooth finish with no sharp edges or burrs, so you are not risking scratches on the mainboard surface or nearby components while positioning it under tight workspace conditions. In your day-to-day workflow, this sheet fits naturally alongside your hot air rework station, reballing kit, and PCB holder — you use it whenever a CPU, GPU, or baseband IC needs targeted heat protection during removal or reinstallation, and it works just as well when you are doing IC change karna on a board with several closely packed components. For UFS or eMMC chip work where precision heating matters, having a heat sink sheet nearby reduces the risk of damaging adjacent flash storage ICs while you focus hot air on the target chip. The 12.45x14mm sheet size covers most standard chip footprints found on current Android and iPhone mainboards, so you rarely need to trim or reshape it before use, and the 50-piece pack means you are not pausing your workshop schedule to reorder after a few jobs. Whether you run a mobile service center handling volume repairs or work independently on a repair bench, this copper sheet earns its place in your toolkit as a low-cost, high-frequency consumable that directly reduces board damage risk during hot air and soldering work, which in turn protects your reputation on repairs that involve dead phone recovery and complex board-level fault finding.
