LZ610 is an 8mm narrow-width dedicated carrier tape developed for miniature 2121 surface-mount LEDs. 2121 micro LEDs are widely applied in mini backlight screens, indicator lights, wearable devices and smart panel displays, whose ultra-small chip body puts strict requirements on cavity symmetry, static shielding and light blocking performance. Different from asymmetrical general carrier tapes on the market, LZ610 adopts equal-width & equal-length 2.44mm square cavity to realize centering fixation of square LED chips, completely solving the offset, tilting and light decay problems of micro components during transportation and assembly. The integral conductive black PC raw material realizes uniform static dissipation without surface coating shedding, meeting long-cycle turnover and stock storage standards of LED packaging factories.
Core Specifications (Compliant with EIA-481 Industry Standards)
| Parameter Name | EIA-481 Industry Standard (mm) | Hatro Custom Parameter (mm) | Practical Advantages |
|---|---|---|---|
| W (Tape Width) | 8±0.10 | 8 | Universal 8mm width fits all mainstream domestic and imported taping & pick-and-place machines, no equipment modification required |
| P1 (Feed Hole Pitch) | 4±0.10 | 4 | Standard 4mm sprocket pitch delivers stable traction, effectively eliminating hole skip and tape jam in uninterrupted high-speed production |
| T (Base Thickness) | 0.20±0.02 | 0.20 | Standard thin substrate balances flexibility and forming flatness, won’t hard curl after thousands of winding layers on reels |
| A0 (Cavity Width) | 2.44±0.05 | 2.44 | Symmetrical square pocket width locks 2121 LED horizontally, zero left-right component offset |
| B0 (Cavity Length) | 2.44±0.05 | 2.44 | Equal square length realizes full centering of square LED chips, prevents front-back sliding and component tipping |
| K0 (Cavity Depth) | 1.40±0.05 | 1.40 | Moderate depth matches standard SMT suction nozzle height, greatly cuts empty pick rate of tiny LEDs |
| D1 (Draft Angle) | 1.00 | 1.00 | Balanced demolding angle ensures smooth mold stripping during production and effortless chip ejection during mounting |

Q&A Session
Q: What advantages does the symmetrical square cavity bring to 2121 LED packaging compared with rectangular pockets?
A: 2121 LED chips are square in outline; rectangular cavities leave large gaps leading to chip shifting. LZ610’s equal-side square pocket tightly wraps the whole chip to maintain centering, ensuring consistent light output after SMT mounting and reducing defective display products.
Q: Why choose integrated conductive PC instead of surface-sprayed anti-static tape?
A: Surface-sprayed anti-static coating will wear off after friction during taping and transportation, losing static protection. Our PC material mixes conductive agent inside raw material, stable ESD performance lasts the whole storage and production cycle.
