LZ611 is a 12mm wide low-cost carrier tape independently developed for flat 4014 linear SMD LEDs, which are the core lamp bead of LED soft light strips, hard bar lights and cabinet atmosphere lights. Mass light strip manufacturers face high packaging material cost pressure for long-run orders, so Hatro selects modified black PS material to replace high-priced pure PC while retaining qualified anti-static and light-shielding performance. The customized ultra-shallow 0.92mm cavity perfectly fits the thin flat profile of 4014 LEDs, preventing chips from sinking deep into the pocket and causing suction nozzle pick failure during high-speed SMT processing. Standard 4mm feed hole pitch ensures stable feeding on all 12mm wide taping machines, suitable for large-scale continuous production of lighting enterprises.

Core Product Strengths
- Low-Cost Modified PS Material: Greatly reduces raw material cost compared with PC carrier tape, ideal for lighting factories pursuing budget control on mass light strip orders.
- Ultra-Shallow Shallow Pocket Design for Flat 4014 LEDs: 0.92mm shallow depth solves the common empty pick fault of flat thin lamp beads in deep-cavity general tapes.
- Lightweight Base Reduces Logistics Cost: PS material has lower density than PC, full tape reel weight drops obviously to cut ocean and land freight for large batch shipments.
- Opaque Black Light-Shielding Performance: Blocks external light irradiation to slow down LED chip light decay, maintaining consistent luminous performance before assembly.
- Stable Mass Production Supply Chain: Mature PS forming process supports large-volume fast delivery, stable dimensional tolerance without batch-to-batch difference.
Application Fields
- 4014 SMD linear LEDs for LED soft light strips, cabinet atmosphere lights, advertising light boxes, indoor decorative lighting
- Large-scale lighting manufacturers with long-term mass production orders and strict procurement budget control
- 12mm wide-width SMT production lines processing flat thin-profile miniature lamp beads
Q&A Session
Q: What is the core cost advantage of LZ611 PS carrier tape compared with PC tape for 4014 LEDs?
A: Modified black PS raw material price is far lower than conductive PC, and PS tape is lighter per meter. Customers can save both raw material purchasing expense and transportation freight when placing million-meter bulk orders, without sacrificing basic anti-static and light shielding functions needed for LED packaging.
Q: Why design an ultra-shallow 0.92mm cavity instead of standard deeper pockets for 4014 LEDs?
A: 4014 lamp beads are ultra-flat thin components; deep cavities make the chip sink too far inside the pocket, leading the SMT suction nozzle unable to touch the chip surface and causing frequent empty pick alarms. The 0.92mm shallow pocket keeps the chip close to the tape surface for stable pickup.
