With the development of new energy, automotive electronics and industrial control fields, the packaging demand for medium and high power semiconductor devices (such as high-power MOS tubes, IGBT modules, rectifier bridges) is increasing day by day. These devices are larger in size and heavier in weight, putting forward higher requirements for the firmness, protection and mechanical strength of tape-and-reel packaging. As an exclusive matching option for 24mm carrier tape, 21.3mm cover tape is the core choice for medium and high power device packaging, and its sealing strength and peeling stability directly determine the safety of device packaging and placement.
Targeting the packaging pain points of medium and high power devices, Hatro has created a 21.3mm high-firmness heat-seal cover tape based on the high-performance EC600-N2 substrate. With the core advantages of strong sealing, tension resistance and long-lasting protection, it perfectly matches 24mm carrier tape, provides reliable full-process protection for medium and high power devices from packaging to placement, and becomes the preferred packaging and testing material for new energy and automotive-grade fields.
High-Firmness Sealing, No Falling Off for Heavy Devices
Medium and high power devices are heavy and prone to cover tape falling off and component displacement during transportation and placement. Hatro’s 21.3mm cover tape optimizes the heat-sealing coating formula with a sealing strength of ≥0.8N/mm, far higher than the conventional cover tape standard. After heat-sealing with 24mm carrier tape, it can withstand strong vibration, stacking extrusion and high-speed tape pulling, without cracking, falling off or displacement, ensuring the stable protection of heavy devices throughout storage, transportation and placement. At the same time, the peel force is stably at 30-90g.f, which not only ensures firm sealing, but also achieves smooth peeling, avoiding carrier tape breakage caused by excessive resistance when the placement machine pulls the tape.
Super Mechanical Performance, Adapting to High-Speed Heavy Feeding
After the 24mm carrier tape is matched with medium and high power devices, the mechanical strength requirements for the cover tape are extremely high during feeding. Relying on the excellent characteristics of the EC600-N2 substrate, Hatro’s 21.3mm cover tape achieves a tensile strength of ≥20N and an elongation at break of ≥90%, with outstanding tension, tear and winding resistance: during high-speed placement machine feeding, the cover tape can withstand continuous pulling force without cracking or breaking; when wound into a reel, there is no crease or deformation, ensuring smooth feeding throughout the process, completely solving the pain point of cover tape damage during heavy device feeding.
All-Dimensional Hard-Core Protection, More Assured with Automotive-Grade Quality
Targeting the high-reliability requirements of automotive-grade application scenarios such as new energy and automotive electronics, the 21.3mm cover tape has all performance benchmarked against automotive standards: in terms of ESD protection, the surface resistivity is 10⁶~10¹¹Ω/sq, with long-lasting electrostatic dissipation to avoid electrostatic breakdown of high-power devices; in terms of optical properties, the light transmittance is ≥80% and the haze is ≤30%, adapting to high-precision AOI testing of automotive-grade production lines; in terms of environmental resistance, it can maintain stable performance in a high and low temperature environment of -40℃~125℃, and after high and low temperature cycle and high humidity testing, the peel force and sealing strength have no attenuation, meeting the stringent use requirements of automotive-grade devices.
Standardized Production, More Stable Mass Supply
This cover tape is produced in Hatro’s Class 100,000 cleanroom with standardized production processes, fully following the ISO9001 and IATF16949 quality systems. From raw material incoming inspection to finished product delivery, it undergoes multiple quality controls such as 3D visual inspection and full performance inspection. The size and performance of each roll of cover tape are stable and consistent with a CPK of ≥6.0, supporting stable mass supply. Widely applicable to high-power MOS tubes, IGBT modules, automotive-grade diodes, industrial rectifier bridges and other devices packaged with 24mm carrier tape, it is the core packaging and testing material for new energy vehicles, photovoltaic inverters, industrial frequency converters and other fields.
