Hatro PPAK Carrier Tape: Customized to EIA-481 Standard for Reliable Power Semiconductor Packaging
In power electronics, automotive power systems, and industrial drive applications, PPAK packages are widely used for their excellent heat dissipation and high current-carrying capacity. However, these large-sized devices with special pin structures impose extremely high requirements on carrier tape cavity accuracy, structural rigidity, and feeding stability. Even minor dimension mismatches can cause jamming, misalignment, missed picks, and high rejection rates, severely hindering production line efficiency.
For a long time, many manufacturers had to rely on imported PPAK carrier tapes, which were costly, had long lead times, and slow customization responses. Today, Xiamen Hatro Electronics Co., Ltd. has launched a PPAK-specific custom carrier tape based on real production line pain points. Strictly following the EIA-481 international industry standard, and precisely matched to customers' actual devices, Hatro provides a reliable domestic solution for power semiconductor placement with real parameters, real performance, and real yield improvements.
1. Customized to EIA-481 Standard for Perfect PPAK Device Fit
EIA-481 is the universal international standard for the carrier tape industry, defining basic carrier tape dimensions, structure, and compatibility requirements. On the basis of meeting this standard, Hatro optimizes exclusive dimensions according to the actual shape, pin positions, and pick-and-place machine suction methods of PPAK packages, achieving more precise fit and stable placement.
| Parameter | EIA-481 Industry Standard (with Tolerance) | Hatro Customer Custom Reference (mm) | Key Advantage |
|---|---|---|---|
| W (Tape Width) | 12.0 ± 0.3mm | 12.0 | Stable feeding for mainstream high-speed placement machines, no deviation during operation |
| A0 (Cavity Length) | 6.50 ± 0.05mm | 6.50 | Perfectly fits device contour, no shaking or tilting |
| B0 (Cavity Width) | 5.35 ± 0.05mm | 5.35 | Protects pins from extrusion, ensures smooth picking |
| K0 (Cavity Depth) | 1.40 ± 0.03mm | 1.40 | Accurate pick position for nozzles, reduces rejection and misalignment |
| P0 (Sprocket Pitch) | 8.0 ± 0.1mm | 8.0 | Excellent feeding synchronization, no component loss during high-speed placement |
All dimensions are formed by independent precision molds and fully inspected via 3D vision, ensuring every roll of carrier tape stably adapts to SMT production lines and eliminates abnormal downtime from the source.
2. Verified Performance: Antistatic, Transport-Resistant, and Heat-Seal Stable
1. Long-Lasting Antistatic Protection for Power Devices
PPAK devices are mostly used in power and drive products, making them sensitive to electrostatic discharge (ESD). Hatro PPAK carrier tape uses stable antistatic PC substrate, continuously protecting devices during storage, transportation, and placement, avoiding ESD breakdown risks, and meeting the requirements of automotive-grade and industrial-grade applications.
2. Stable Heat Sealing for Smooth Cover Tape Peeling
The heat-sealing surface of the carrier tape is professionally treated, with good compatibility with standard cover tapes. The peel force is uniform and stable, ensuring smooth opening without flying components or dropping, enabling continuous operation of automated production lines without frequent machine adjustments.
3. High Rigidity for Deformation Resistance
The carrier tape balances toughness and rigidity, with strictly controlled warpage. It resists deformation during stacking and long-distance transportation, providing reliable protection for large-sized PPAK devices and reducing material loss.
3. Verified Quality Control for Visible Reliability
Hatro PPAK carrier tapes are produced in a Class 100,000 cleanroom, with full implementation of standardized quality control processes:
- Incoming material inspection
- In-process patrol inspection
- Finished product dimension and performance inspection
- 3D visual inspection for dimension consistency
Products comply with RoHS and REACH environmental requirements, with stable and traceable quality, suitable for long-term mass supply.
