In SMT placement production lines, 8mm embossed carrier tape is the mainstream choice for micro-semiconductor device packaging, and the selection of matching cover tape width directly determines sealing compatibility and placement yield. Per the industry universal standard, 8mm carrier tape must be paired with 5.4mm cover tape—even a 0.1mm precision deviation in this gold combination can cause poor sealing, peeling jamming, component flying and other issues.
Xiamen Hatro Electronics, relying on independently developed EC600-N2 substrate, has created an exclusive 5.4mm precision heat-seal cover tape. It has been rigorously optimized for dimensional accuracy, ESD protection, peel force stability and mechanical performance based on national standards, perfectly meeting the sealing and placement requirements of 8mm carrier tape. It is a reliable choice for packaging devices such as SOT23, 0402/0603 passive components and micro ICs, and builds a solid packaging and protection barrier for micro-semiconductors with hard-core tested data.
Core Hard-Core Parameters, Precisely Matching 8mm Carrier Tape Requirements
Hatro’s 5.4mm cover tape is built on the EC600-N2 substrate, with all performance indicators certified by national standard testing. Core parameters such as dimensional accuracy, ESD protection and peel strength are targeted to adapt to the sealing and high-speed placement scenarios of 8mm carrier tape. The measured data is traceable throughout the process, making every sealing and peeling operation stable and controllable.

Three Core Advantages, Solving Packaging and Placement Pain Points of 8mm Carrier Tape
🌟 Precisely Controllable Peel Force, Zero Abnormality in High-Speed Placement
For the high-speed placement scenarios matched with 8mm carrier tape, Hatro’s 5.4mm cover tape creates a 30-90g.f optimal peel force range, and realizes stable and controllable peel force at different temperatures through a precise heat-sealing temperature gradient design, perfectly adapting to full-range heat-sealing equipment from 120℃ to 180℃:
- 120℃ heat sealing: Peel force 20-40g.f, suitable for packaging of heat-sensitive devices
- 150℃ heat sealing: Peel force 55-75g.f, universal for mainstream placement scenarios
- 180℃ heat sealing: Peel force 85-105g.f, suitable for high-firmness sealing requirements
Under laboratory standardized test conditions (0.3Mpa sealing pressure, 0.8mm sealing width, 0.2sec sealing time), the peel force fluctuation rate is ≤5%. During the tape pulling process of high-speed placement machines, the cover tape is opened smoothly without flying components, adhesion or breaking, and the placement yield is raised to over 99.9%.
🌟 Long-Lasting ESD Protection, All-Round Safety for Micro Devices
Micro semiconductor devices (such as SOT23 transistors, 0402 resistors and capacitors) are highly sensitive to static electricity. Hatro’s 5.4mm cover tape adopts PE conductive substrate + uniformly blended antistatic formula, with surface resistivity stably controlled at 10⁶~10¹¹Ω/sq, complying with ESD protection standards:
- The electrostatic dissipation performance is long-lasting and stable, protecting devices throughout storage, transportation and placement, and avoiding functional failure caused by electrostatic breakdown;
- The light gray substrate design not only avoids glare in AOI inspection under strong light, but also effectively shields external electrostatic interference, adapting to the packaging requirements of precision devices.
🌟 Extreme Dimensional Accuracy, 100% Compatibility with 8mm Carrier Tape
Relying on high-precision slitting technology, Hatro’s 5.4mm cover tape achieves a width tolerance of ±0.1mm for slitted products, and large jumbo rolls can also ensure precise size control of 0~5mm. Combined with a uniform thickness of 52±5μm, when sealed with 8mm carrier tape:
- The sealing surface is fully attached without edge warping or middle missing seal, forming a closed protective space to isolate dust, moisture and oil pollution from damaging the device;
- The sealing point avoids the PET layer at the edge of the cover tape, fundamentally avoiding delamination and tape breakage caused by excessive sealing, and ensuring the continuous operation of the automated production line.
Standardized Storage and Usage, Ensuring Stable Performance Throughout
✅ Professional Storage Conditions, 1-Year Long-Term Stability
Hatro’s 5.4mm cover tape can achieve a 1-year storage life with no performance attenuation when stored in a clean, dry and ventilated warehouse with temperature 0℃-45℃ and humidity 40%RH-60%RH. During storage, avoid direct sunlight, rain contact and organic solvent pollution, and keep it at least 1m away from heat sources to prevent material aging and deformation.
✅ Standard Usage Requirements, More Efficient Sealing and Placement
- Continuous heat sealing is recommended for heat sealing, with sealing pressure 0.3Mpa, sealing width 0.8mm and sealing time 0.2sec. Fine-tuning can be made according to actual equipment to ensure the peel force is in the optimal range of 30-90g.f;
- The sealing point should be at least 0.5mm from the edge of the cover tape to avoid damaging the PET substrate and causing delamination;
- Adapt to all types of standard SMT heat-sealing equipment, and the sealing and placement effect is better when used with Hatro’s 8mm precision carrier tape.

Q&A
Q: Why is 5.4mm cover tape the exclusive partner for 8mm carrier tape?
A: This is the universal matching standard in the SMT packaging industry. The 5.4mm width precisely matches the sealing edge of 8mm carrier tape. An over-wide cover tape will cause the sealing to cover the device cavity, while an over-narrow one cannot achieve effective sealing. The combination of the two can achieve the best sealing and placement effect.
Q: Can this cover tape be adapted to heat-sensitive micro devices?
A: Yes. Under low-temperature heat sealing at 120℃, the peel force of the cover tape can be controlled at 20-40g.f, which can achieve firm sealing and avoid damage to heat-sensitive devices caused by high temperature.
Q: What is the special function of the light gray substrate of the cover tape?
A: On the one hand, the light gray substrate can effectively shield external electrostatic interference and improve the ESD protection effect; on the other hand, it can avoid glare in AOI optical inspection under strong light and ensure the accuracy of device identification.
Q: Can the cover tape stored for more than 1 year still be used?
A: It is recommended to use the cover tape within the 1-year storage period. After the storage period, the antistatic performance and heat-sealing compatibility of the cover tape may attenuate, affecting the packaging and placement effect.
Q: Can the cover tape width be customized according to my production line equipment?
A: Yes. Hatro supports the customized production of cover tapes of various specifications, and can precisely adjust the cover tape width, thickness and peel force parameters according to the customer’s carrier tape size and equipment parameters.
