LZ619 is a wide-format carrier tape specially engineered for ultra-flat 010 size miniature electronic components. Conventional deep-cavity carrier tapes cause thin flat chips to sink too far inside the pocket, leading to frequent nozzle pick failure and production downtime. To solve this long-standing industry pain point, Hatro designs an ultra-shallow 0.60mm pocket that keeps 010 parts nearly flush with the tape surface, ensuring stable pickup in continuous high-speed assembly lines.
The 0.20mm thin PC base maintains good flexibility without permanent curling after multi-layer reel winding. The 0.50° small demolding angle reduces mold sticking during mass forming, improving production yield. The long narrow cavity (A0=1.20mm, B0=4.05mm) perfectly matches the strip-shaped outline of 010 components, limiting left-right and front-back sliding to avoid component tilting. The black opaque PC material delivers basic light-shielding performance to protect photosensitive miniature chips from light aging during long-term storage. All dimensions strictly comply with EIA-481 international carrier tape standards, fully compatible with mainstream 12mm taping and SMT placement machines worldwide.

Q&A
Q: Why design such a shallow 0.60mm pocket for 010 flat components?
A: 010 chips are ultra-thin flat parts. Deep pockets make the component sink deep inside the cavity, so the suction nozzle cannot fully touch the chip surface, causing repeated pick failures. The ultra-shallow pocket keeps the part close to the tape surface to ensure stable pickup every cycle.
Q: What is the advantage of the 0.50° small demolding angle?
A: Gentle draft angle reduces the friction between raw material and mold walls during thermoforming, lowering the rate of mold sticking and blemishes on pocket inner walls, which helps maintain consistent quality in 24-hour continuous mass production.
