Hatro 3528 Carrier Tape | Precision for 3528 Packaging, High-Efficiency Solution for LED & Micro Semiconductor Packaging
1. Product Overview
3528 packaging is a mainstream packaging form for LED beads and micro semiconductor devices, widely used in consumer electronics, automotive electronics, industrial control, lighting and other fields. Targeting the exclusive needs of 3528 packaging, Hatro develops and produces 3528 special carrier tape. With precise size design, high-quality material performance and full-process supporting services, it provides full-link protection for 3528 packaged LED beads and micro devices from packaging, storage, transportation to SMT placement. Relying on the advantage of full industrial chain independence, it breaks overseas dependence and becomes the ideal carrier tape supporting choice for 3528 packaged devices.
2. Core Specifications (Compliant with EIA-481 Industry Standards, Full-Size Customization Available)
| Parameter Name | EIA-481 Industry Standard (mm) | Hatro Custom Parameter (mm) | Practical Advantages |
|---|---|---|---|
| W (Tape Width) | 8±0.10 | 8 | High-speed feeding without deviation, perfectly compatible with mainstream placement machines and taping machines, no additional debugging required |
| A0 (Cavity Width) | 3.05±0.10 | 3.05 | Fits the contour of 3528 devices, eliminating shaking, jamming and tipping, ensuring placement stability |
| B0 (Cavity Length) | 3.70±0.10 | 3.70 | Precisely matches device size, protects device pins/LED beads from extrusion deformation and picking deviation |

All parameters are strictly controlled by Hatro's self-developed high-precision molding molds and online 3D visual inspection system, with tolerances strictly within high industry standards. It can be adapted to 10,000-level high-speed SMT placement machines, fundamentally eliminating placement abnormalities such as jamming, deviation and dropping, and ensuring continuous and stable operation of the production line. Full-size customization is available, and the cavity specifications can be adjusted 1:1 according to the special needs of customer devices to achieve exclusive adaptation.
3. Product Advantages
- Precision Customization, Zero Deviation Placement for LED & Micro Devices: 1:1 customized cavity size for 3528 packaged LED beads and micro devices, tight fit without gaps, completely solving the pain point of poor compatibility of conventional carrier tapes. The placement yield is increased to over 99.9%, greatly reducing device loss and production line rework costs.
- High-Quality Material, Full-Strength Performance: Made of high-purity new black PC (Polycarbonate) substrate with self-developed modification technology, it has excellent impact resistance and bending resistance, can withstand the weight of devices, no whitening or breaking during winding; the temperature resistance range is extended to -40℃~120℃, adapting to high-temperature environments of LED production lines; low precipitation and high cleanliness, complying with RoHS and REACH environmental standards, suitable for automotive-grade and industrial-grade high-end packaging scenarios; black material has strong light shielding, which can effectively protect photosensitive LED devices from light affecting performance and lifespan.
- Full-Area Anti-Static, Protect Sensitive Devices: The surface of the carrier tape 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 3528 sensitive devices and ensuring the integrity of device electrical performance.
- 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.
- Independent Control, Cost Optimization: Core technologies are fully independently developed, with local large-scale mass production. The cost is reduced by more than 30% compared with imported similar products, getting rid of dependence on overseas technology and supply chains, ensuring supply chain safety, and helping enterprises reduce costs and increase efficiency.
- Strict Quality Control, Traceable Quality: Complying with ISO9001 and IATF16949 quality systems, each batch of carrier tapes undergoes full-size inspection, anti-static testing and mechanical performance testing, with a yield rate of over 99.9%. The whole process data is traceable, and the quality is stable and reliable.

5. Q&A
Q: What's the difference between 3528 carrier tape and ordinary carrier tape? Why must we use the special one?A: The core difference lies in "compatibility + strength"! Ordinary carrier tapes are universal, which not only cannot accurately match the size of 3528 devices, but also are prone to carrier tape deformation and device falling due to insufficient strength, which directly reduces the production line yield and increases the loss cost of LED beads and other devices. Our 3528 special carrier tape is completely customized 1:1 for 3528 packaging, with precise cavity size matching and full strength of PC material. The device fits tightly when put in, and the placement is smooth without mistakes. It fundamentally solves all compatibility pain points and maximizes the production line efficiency.
Q: Why choose new black PC material instead of traditional PS?A: Because black PC material is the "ceiling" of 3528 carrier tapes! Compared with traditional PS, PC material is comprehensively superior in toughness, heat resistance and impact resistance, can easily withstand the weight of devices, 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 LED and other photosensitive devices from light affecting performance and lifespan. It can be easily adapted to ordinary consumer electronics, as well as automotive-grade and industrial-grade high-end scenarios, making it more worry-free and reliable to use.
