LZ612 is an exclusive 16mm ultra-wide carrier tape targeting oversized 7020 SMD LEDs, which are widely used in high-brightness panel backlights, outdoor advertising light boxes and high-power linear light strips. Conventional 8/12mm narrow tapes cannot fully contain the long outline of 7020 lamp beads, leading to component extrusion and pick failure. Hatro designs a full 16mm wide tape body paired with a 7.19×2.24×1.02mm elongated cavity to fully wrap the large flat LED chip, eliminating shaking, tilting and surface scratch during high-speed taping and mounting.
Modified conductive PS material greatly cuts overall packaging cost compared with pure PC wide tape, while retaining uniform permanent anti-static performance between 10⁶~10⁹Ω/sq. The 0.25mm thickened PS base enhances flatness and anti-curling performance, solving the easy-warp defect of thin wide-width tapes after long reel stacking. The standard 4mm feed hole pitch ensures stable traction on all 16mm wide-format taping machines, supporting 24-hour uninterrupted mass production for lighting factories.

Q&A
Q: Why choose 16mm ultra-wide tape instead of 12mm tape for 7020 LEDs?
A: The overall length of 7020 lamp beads reaches 7.19mm; 12mm tape’s maximum available cavity length cannot fully accommodate the chip, which will cause component extrusion and lamp bead damage during winding. LZ612’s 16mm width reserves enough space for the long outline of 7020 LEDs to fully protect components.
Q: What are the cost advantages of PS material compared with conductive PC wide tape?
A: Modified conductive PS raw material has lower market price, and PS tape is lighter per unit length, reducing both material purchase cost and cross-border logistics freight for large shipments, without losing basic ESD and light shielding functions required for LED packaging.
