LZ625 is a high-rigidity wide transparent carrier tape engineered exclusively for thick, tall 4532 rectangular SMD components. Tall 4532 chips cannot fit inside shallow standard pockets, and thin transparent carrier tapes easily deform under the heavy weight of these components.
Hatro upgrades LZ625 with a 0.25mm thick high-clarity transparent PC substrate to greatly enhance bending resistance, eliminating curling on heavy full reels. The oversized 3.50×4.70×3.20mm deep cavity fully encloses the thick 4532 chip body without pin extrusion or surface abrasion. The widened 8mm feed hole pitch delivers powerful traction for heavy wide tape rolls, preventing feeding slip and jamming during high-speed continuous taping. The high-transparency PC material allows operators and machine vision systems to check component position, tilt and surface defects directly through the tape body, cutting cover tape consumption and shortening QC cycle time. The 1.50° demolding angle ensures smooth mold stripping and reliable SMT nozzle pickup. All dimensions conform strictly to EIA-481 global carrier tape specifications, compatible with all mainstream 12mm wide taping and placement machines.

Core Competitive Advantages
- 3.20mm Ultra-Deep High-Capacity Cavity: The deep pocket fully contains tall 4532 thick components without squeezing pins or chip surfaces.
- 0.25mm Thickened Rigid Transparent PC: Solves the softness and curling defects of thin clear tape when carrying heavy thick components, maintaining reel flatness.
- Full Transparent Body for Zero-Waste Visual QC: Inline inspection without peeling cover tape drastically reduces packaging waste and labor cost for quality checking.
- 8mm Widened Feed Hole Traction: Prevents slip and deviation when running heavy full reels on 12mm high-speed production lines.
- Non-Yellowing High-Clarity Virgin PC: The transparent material stays clear and haze-free after long-term stock storage, supporting continuous visual inspection for months.
Application Scenarios
- 4532 thick rectangular SMD resistors, capacitors and power discrete components
- Packaging production lines requiring 100% manual or AI vision inline quality inspection
- 12mm wide-format mass production lines with heavy component reels and strict flatness requirements
Q&A Session
Q: Why design a 3.20mm ultra-deep pocket for 4532 components?
A: 4532 chips have a large thickness compared with ordinary flat SMD parts. Ordinary shallow pockets will press the top of the component and bend delicate pins. The ultra-deep cavity provides enough vertical clearance to fully hold the tall chip without compression.
Q: What benefit does the 0.25mm thick transparent PC bring compared with thin 0.20mm clear tape?
A: Transparent PC has lower inherent rigidity than black conductive PC. When wound with heavy thick 4532 components, thin 0.20mm clear tape will permanently curl. The upgraded 0.25mm thickness strengthens the tape structure to keep it flat during the whole production and shipping cycle.
