2UUL ST11 Pre-Cut Heat Shrink Tubing 200pcs set

Every technician who has fixed a dead phone through ISP or eMMC jumper wires knows the frustrating moment: the joint works, the board boots, and then a bare wire touches a shield can and the repair starts over. The 2UUL ST11 Pre-Cut Heat Shrink Tubing 200pcs set removes that risk from your repair bench by giving you a ready supply of insulation sleeves that slide over the wire before you solder and shrink tight after you finish. Because the tubes arrive pre-cut, you skip the measuring and trimming step and go straight from soldering to insulating, which saves real minutes when you handle a stack of boards in one day. The set holds 200 pieces of polyolefin heat shrink tubing in three supplied inner diameters, 6 mm, 8 mm, and 10 mm, with red, blue, green, and white options across the range. Polyolefin shrinks at a 2:1 ratio, so every sleeve tightens down to half of its supplied diameter and grips the wire or cable instead of hanging loose. Shrinking starts at a minimum of 70°C and finishes at a maximum of 110°C, which means you can complete the job with your hot air station on a modest temperature and gentle airflow instead of blasting heat toward nearby components. Once shrunk, the material works across a range from -55°C to 125°C, carries a tensile strength of 10.4 MPa, and resists flame, so the insulation keeps its shape on a busy workshop bench. Start with the ISP workflow. When you jumper lagana on a dead after flash board, you solder thin wires to test points and route them out to an ISP pinout tool, an eMMC programmer, a UFS adapter, or a test box. Slip a sleeve over each joint and the exposed copper stays covered while you carry the board to your microscope or clamp it in your PCB holder. Use the four colors as a signal code, red for power, blue for data, green for clock, and white for ground, or follow any scheme your workshop agrees on. Your next technician reads the wire map at a glance instead of chasing each line with a multimeter. The same logic covers everyday repairs outside ISP work. When you rebuild a broken charging cable, repair a torn battery lead, patch a speaker or headphone wire, or fix a wire on a charging port line after a charging issue, a sleeve protects the joint from bending stress and accidental contact. Choose the smallest supplied diameter that still slides over your wire and its solder joint, so the sleeve grips the joint tightly after shrinking. Thread the sleeve onto the wire first, finish your solder joint, let the joint cool, then slide the sleeve over it and apply heat. Hold the hot air nozzle a few centimeters away and move it along the tube so the shrink stays even. Keep the set beside your soldering station and reballing kits so you grab a sleeve before the iron heats up, not after you spot a bare joint. For repair shops, service centers, and training institutes in Pakistan, a 200-piece set covers heavy daily use, and the mixed sizes and colors mean one purchase serves ISP work, cable repair, and bench organization at the same time. Pair the 2UUL ST11 tubing with a reliable soldering station, a hot air station with adjustable airflow, and a good microscope, and you build a clean insulation routine into every job that leaves your bench.
