Hatro LZ618 Three-Layer Reinforced Carrier Tape | Custom 12mm Pure Black PC Packaging Tape Optimized for Yiguang 99-218G LED Chips
LZ618 is a high-performance wide-format carrier tape built exclusively for ultra-flat thin 99-218G linear LEDs produced by Yiguang, widely used in soft light strips, cabinet atmosphere lights and commercial decorative lighting. Conventional single-layer PC carrier tapes suffer insufficient tensile strength and easy curling after long reel winding, which triggers feeding faults on wide-width taping machines. Hatro innovates a three-layer co-extruded pure black PC structure for LZ618, greatly lifting structural rigidity, tensile resistance and dimensional stability under long-term stacking and winding load.The customized ultra-shallow 0.66mm pocket perfectly fits the ultra-thin flat outline of 99-218G lamp beads, solving the common empty pick failure issue caused by chips sinking deep into standard deep cavities. The thickened 0.25mm three-layer composite base maintains consistent flatness even after months of cold warehouse storage, and the opaque black three-layer material completely blocks ambient light irradiation to slow down light decay of high-brightness LED chips, stabilizing luminous consistency before SMT assembly. Standard 4mm feed hole pitch ensures compatible stable feeding on all global 12mm wide taping equipment, supporting uninterrupted 24-hour mass production for lighting enterprises.
Complete Technical Parameter Table
| Parameter Name | EIA-481 Standard Tolerance (mm) | LZ618 Custom Value (mm) | Practical Production Advantages |
|---|---|---|---|
| W Tape Width | 12±0.10 | 12 | Standard wide width compatible with all mainstream wide-format taping and SMT placement machines for long linear LED strips |
| P1 Feed Hole Pitch | 4±0.10 | 4 | Universal sprocket hole pitch matches global SMT machine standards, avoids tape deviation and jamming during continuous high-speed operation |
| T Base Thickness | 0.25±0.02 | 0.25 | Three-layer composite thick substrate maximizes tensile rigidity, completely eliminates curling deformation after long-time reel stacking |
| A0 Cavity Width | 1.13±0.05 | 1.13 | Narrow pocket width fits the thin horizontal side of flat 99-218G LED, restricts horizontal chip offset |
| B0 Cavity Length | 4.03±0.05 | 4.03 | Long customized cavity fully covers the full longitudinal outline of linear lamp beads, prevents front-back sliding and component overturn |
| K0 Cavity Depth | 0.66±0.05 | 0.66 | Ultra-shallow flat pocket keeps thin LED close to tape surface for reliable suction nozzle pickup, cuts empty pick alarm frequency |
| D1 Draft Angle | 1.50 | 1.50 | Wide demolding angle accelerates three-layer mold forming cycle and ensures smooth chip ejection during SMT mounting |
Core Competitive Strengths
Unique Three-Layer Co-Extruded Pure PC Structure: Tensile strength and flatness far exceed single-layer PC carrier tape, no cracking or curling under heavy winding tension of wide LED reels.
Ultra-Shallow Flat Pocket Exclusive for Thin 99-218G Linear LEDs: Solves the industry-wide empty pick defect of ultra-flat lamp beads in deep-cavity generic tapes, greatly improving SMT production uptime.
0.25mm Reinforced Three-Layer Thick Base: Superior anti-deformation performance under long-term storage and cold environment, stable feeding for multi-month stock reels.
Full Opaque Three-Layer Black Light Shielding: Double-sided light barrier prevents photoaging of LED chips, maintaining uniform brightness for finished light strip products.
Stable Mass Production & Custom Support: Mature three-layer forming production line supports million-meter bulk delivery, dedicated technical team adjusts cavity dimensions for special variant 99-218G LED sizes, fast 3-day mold sampling.

Q&A Session
Q: What performance advantages does the three-layer pure PC structure bring compared with ordinary single-layer PC carrier tape?A: Single-layer PC tape has weak tensile strength and easily curls after long winding of heavy wide LED reels, causing machine feeding alarms. Our three-layer co-extruded composite structure greatly boosts overall rigidity and tensile resistance, keeping the tape flat throughout forming, logistics and storage cycles, and extending the service life of finished tape reels.Q: Why design an ultra-shallow 0.66mm cavity for 99-218G flat LEDs?A: 99-218G lamp beads are ultra-thin flat components. Deep standard pockets make the chip sink too far into the cavity, so the SMT suction nozzle cannot fully contact the chip surface and leads to frequent empty pick faults. The 0.66mm ultra-shallow pocket holds the lamp bead flush with the tape surface for consistent, reliable pickup every cycle.
