KD1881S transparent Heat Activated Adhesive (HAA) cover tape is primarily suitable for SMT-type inductor and precision connector packaging applications. Its core advantages include a standard thickness of 0.058±0.005mm and high double-sided surface resistivity SR (10¹⁰ - 10¹² Ω/cm²). Its transparent appearance (haze 8-13, transparency 85-90) facilitates visual inspection on the production line. Its stable peel force and tensile strengths make it suitable for high-speed placement production lines, ensuring component packaging integrity and placement reliability.

Product Highlights

  1. High optical clarity: Excellent light transmittance facilitates Automated Optical Inspection (AOI) and inline quality control during the packaging process, ensuring clear identification of component status.
  2. Superior sealing performance: Forms a strong, uniform seal upon heat activation to deliver stable component protection and high packaging reliability.
  3. Optimized for PS carrier tapes: Engineered for precise matching with Polystyrene (PS) carrier tapes, ensuring stable, jam-free taping on automated packaging lines.
  4. Halogen-free and eco-friendly: Complies with global environmental standards (RoHS 2.0 / REACH), reducing environmental impact and meeting green supply chain requirements.
