LZ624 is a high-rigidity ultra-wide carrier tape built for long-size 62-129 high-power LEDs, widely used in outdoor high-brightness light strips, large advertising light boxes and landscape lighting projects. Conventional single-layer wide carrier tapes suffer insufficient structural strength; after winding heavy long LED components, the tape body easily curls and deforms, leading to feeding jams on wide-format taping machines.
Hatro innovates a three-layer co-extruded pure black PC formula for LZ624, raising tensile rigidity far above ordinary single-layer PC material. The upgraded 0.31mm ultra-thick substrate completely eliminates permanent bending deformation even after months of reel stacking and cross-border sea transportation. The elongated narrow pocket (A0=2.20mm, B0=7.25mm) perfectly fits the long strip outline of 62-129 lamp beads, limiting horizontal and longitudinal sliding to avoid component tilting. The 1.50° wide demolding angle optimizes continuous thermoforming efficiency and ensures smooth SMT pickup. All dimensions strictly comply with EIA-481 international industry standards, fully compatible with all mainstream 16mm wide-width automated taping equipment.

Core Competitive Advantages
- Three-Layer Co-Extruded Pure PC Structure: Tensile strength and flatness far outperform single-layer PC tape, no curling even with heavy full reels of long LEDs.
- 0.31mm Ultra-Thick Reinforced Substrate: Solves the inherent deformation problem of ultra-wide 16mm carrier tapes after long-term winding and storage.
- Elongated Exclusive Pocket for 62-129 Long LEDs: Precisely matches the long strip outline of high-power lamp beads, effectively preventing component shaking and tilting during transit.
- Full Black Light-Shielding Barrier: Blocks UV and ambient light irradiation to slow down light decay of high-brightness LED chips, stabilizing luminous consistency.
- Large-Volume Mass Production Support: Mature three-layer co-extrusion production line supports million-meter bulk delivery, rapid cavity size adjustment for variant long LED models.
Application Scenarios
- Yiguang 62-129 long high-power SMD LEDs for outdoor light strips, large outdoor advertising light boxes, landscape decorative lighting
- Large lighting enterprises running 16mm ultra-wide continuous SMT production lines
- LED manufacturers with strict flatness requirements for long-term bulk reel inventory
Q&A Session
Q: What advantages does the three-layer PC material bring compared with single-layer PC for 16mm wide tape?
A: Single-layer 16mm wide PC tape has poor structural rigidity; heavy long LED reels will bend the tape permanently after winding. Our three-layer composite structure greatly improves tensile strength and dimensional stability, keeping the tape flat throughout forming, logistics and long-term warehouse storage.
Q: Why adopt an elongated narrow pocket for 62-129 LEDs?
A: 62-129 components are long strip-shaped lamp beads. Ordinary square pockets leave excessive internal clearance, causing the long chip to swing freely and tilt during transportation. The narrow elongated cavity tightly wraps the LED outline and keeps the component centered.
