In the semiconductor packaging field, large-size power devices and modular components (such as high-power IGBT modules, power modules, customized semiconductor components) need to be packaged with 32mm/44mm wide carrier tapes due to their large size and complex structure. As the core matching option for wide carrier tapes, 37.5mm cover tape is a “must-have” for large-size device packaging. Wide-width cover tapes have much higher requirements for dimensional accuracy, sealing uniformity and mechanical strength than conventional ones, and ordinary cover tapes are prone to uneven sealing, edge warping and large peel force fluctuations.
With years of R&D experience in wide-width packaging and testing materials, Hatro has created a 37.5mm wide-width precision heat-seal cover tape based on the EC600-N2 substrate. With ultra-wide precision control, full-domain uniform sealing and super comprehensive performance, it has become a domestic benchmark for large-size device packaging, completely solving the industry pain points of wide-width packaging and providing comprehensive and reliable packaging protection for high-power and modular devices.
Ultra-Wide Precision Control, Meticulous Dimensional Deviation
The dimensional accuracy of the 37.5mm wide-width cover tape directly affects the sealing effect of wide-width carrier tapes. Hatro adopts customized high-precision slitting and forming equipment, strictly follows the national standard GB/T 6673-2001, with the width tolerance of slitted products precisely controlled at ±0.1mm, the width of the whole roll of cover tape is uniform without deflection or uneven width; the full-domain uniform thickness of 52±5μm without thickness difference, when sealed with 32mm/44mm wide carrier tapes, it fits perfectly in the whole domain without edge warping or middle missing seal, realizing the whole-domain closed protection of large-size devices.
Full-Domain Uniform Sealing, No Protection Dead Angle for Large-Size Devices
The most common problem of wide-width cover tapes is the unevenness of “loose middle sealing and tight edge sealing”, which leads to inadequate local protection of devices and tape breakage due to uneven stress during peeling. Hatro’s 37.5mm cover tape optimizes the heat-sealing coating process and adopts full-domain uniform coating technology, with the heat-sealing coating thickness deviation ≤0.005mm. When heat-sealed with wide-width carrier tapes, the full-domain sealing strength is uniform and consistent at ≥0.8N/mm, no sealing dead angle and no uneven stress, ensuring that large-size and modular devices are uniformly protected throughout the process, without displacement or falling off during transportation and placement.
Full-Scale Comprehensive Performance, Full Adaptation to Wide-Width Scenarios
As a high-end wide-width model, the comprehensive performance of the 37.5mm cover tape is fully maximized to meet the stringent packaging requirements of large-size devices: in terms of ESD protection, the surface resistivity is 10⁶~10¹¹Ω/sq, the full-domain electrostatic dissipation is uniform, avoiding local electrostatic accumulation breakdown of large-size devices; in terms of optical properties, the full-domain light transmittance is ≥80% and the haze is ≤30%, no local uneven light transmittance, adapting to wide-width AOI optical inspection with no blind spots in large-size device identification; in terms of mechanical properties, the tensile strength is ≥20N and the elongation at break is ≥90%, excellent tension and tear resistance in the wide-width state, no cracking or breaking during high-speed tape pulling and winding, adapting to the high-speed feeding needs of wide-width carrier tapes.
Full Coverage of High-End Scenarios, More Reliable Domestic Substitution
At present, the wide-width cover tape market is mostly monopolized by imported brands. Hatro’s 37.5mm cover tape has realized the domestic substitution of wide-width cover tapes for high-end fields with the core advantages of performance benchmarking international first-tier brands, more favorable prices and shorter lead times. This cover tape is widely applicable to large-size devices such as high-power IGBT modules, industrial power modules, customized semiconductor components and large-size sensors packaged with 32mm/44mm wide carrier tapes, covering high-end fields such as new energy power generation, rail transit, industrial automation and high-end equipment. At the same time, it provides exclusive technical support, customizing heat-sealing parameters and adaptation solutions according to the structural characteristics of customers’ large-size devices, making wide-width packaging more efficient and reliable.
