3. Product Advantages
- Black PC Material, Full Automotive-Grade Quality: Made of high-purity black PC substrate with self-developed modification technology, specially designed for automotive-grade IC packaging. The black material has strong light shielding, effectively protecting photosensitive IC devices from light affecting performance and lifespan; 40% higher impact and bending resistance, no whitening or breaking during winding, stable size after repeated use; temperature resistance range extended to -40℃~120℃, adapting to various harsh production environments; low precipitation and high cleanliness, complying with RoHS and REACH environmental standards, suitable for automotive-grade and industrial-grade high-end packaging scenarios.
- Exclusive Cavity Structure, Solving Ultra-Thin Device Placement Pain Points: Targeting the ultra-thin and ultra-small structure of DFN3×3, the cavity design is exclusively optimized. The cavity depth precisely matches the device thickness, allowing the nozzle to fit perfectly during picking, completely solving the problems of unstable picking and dropping; the cavity edge is optimized with rounded corners to avoid scratching device pins and protect device integrity; the draft angle is repeatedly simulated and optimized for easy demolding during molding and easy picking during placement, balancing production and placement efficiency.
- Full-Area Anti-Static Protection, Safeguard Sensitive Devices: The carrier tape surface is treated with full-area anti-static, with a stable surface resistance of 10⁶~10⁹Ω/sq. Static electricity dissipates quickly without accumulation, effectively avoiding electrostatic breakdown of DFN3×3 sensitive devices and ensuring complete electrical performance from packaging to placement.
- Full Industrial Chain Collaboration, One-Stop Supporting: Relying on Hatro's full industrial chain advantages of self-developed molds and self-produced materials, it provides one-stop supporting services of carrier tape + cover tape + reel. Products of the same specification are perfectly matched, no multi-party coordination is needed; 3-day rapid mold opening and sampling are supported, customized needs are quickly responded to, and mass supply is stable.
4. Core Strengths of Choosing Hatro

6. Q&A
Q: What's the difference between DFN3×3 carrier tape and ordinary carrier tape? Why must we use the special one?A: The core difference lies in "compatibility + automotive-grade quality"! DFN3×3 is an ultra-thin and ultra-small automotive-grade IC package. The cavity size and depth of ordinary carrier tapes do not match at all, which is prone to device shaking, jamming, dropping and placement deviation, directly reducing production line yield and increasing device loss. Our DFN3×3 special carrier tape is completely customized 1:1 for DFN3×3 packaging, with exclusive optimized cavity size, depth and draft angle. The device fits tightly when put in, and the placement is smooth without mistakes, fundamentally solving all compatibility pain points, while meeting the stringent requirements of automotive-grade standards, making it more reliable to use.
Q: Why choose black PC material instead of traditional PS?A: Because black PC material is the "optimal solution" for DFN3×3 carrier tapes! Compared with traditional PS, PC material is comprehensively superior in toughness, heat resistance and impact resistance, which can better protect ultra-thin automotive-grade ICs, no whitening or breaking during winding, and has a wider temperature resistance range, which can withstand both high-temperature workshops and low-temperature storage. Moreover, the black material has strong light shielding property, which can perfectly protect photosensitive IC devices from light affecting performance and lifespan, suitable for automotive-grade and industrial-grade high-end scenarios, making it more worry-free and reliable to use.
