Solution Overview
ALS Tape provides EMC (electromagnetic compatibility) and EMI (electromagnetic interference) shielding solutions to protect electronic devices from internal interference and external noise. Four material categories address the full EMC requirement: EMI Wave Absorbers absorb electromagnetic waves in specific frequency bands (100 MHz to 6 GHz) using a magnetic metal powder and flexible rubber structure to reduce noise emissions and prevent metal object interference with loop antennas; Conductive Fabrics combine high resistance with high conductivity for shielding and absorption in cable devices, gaskets, and grounding applications — copper (AS-CC, up to 1500 gf/25mm adhesion), AL+PET (AS-CPA), and fabric (AS-CF, 0.08–0.1 Ω surface resistance) variants; Shielding Tapes for display products prevent light leakage (>99.9% light blocking) and provide electrical insulation in Black & Black (light leakage prevention) and White & Black (BLU reflection) configurations; and Conductive Foam structures (urethane foam + base film + acrylic adhesive) for shock absorption and sealing in smartphones and portable devices.
