Hatro LZ635 High-Capacity Clear Carrier Tape | Custom 12mm Transparent PC Packaging Tape for SMA Small-Body Diodes
LZ635 is a high-rigidity wide transparent carrier tape engineered exclusively for tall SMA small-body diodes. Ordinary shallow carrier tapes cannot hold the tall vertical profile of SMA diodes, leading to pin bending; thin transparent tape also easily deforms under the weight of these components.
Hatro upgrades LZ635 with a 0.22mm thick high-clarity transparent PC substrate to greatly enhance bending resistance, eliminating curling on heavy full reels loaded with diodes. The customized 2.79×5.33×2.45mm deep cavity fully encloses the tall SMA small-body diode without pin extrusion or lead abrasion. The fully transparent high-clarity PC material lets operators and machine vision systems inspect component placement, tilt and surface defects directly through the tape body, cutting cover tape waste and shortening QC cycle time. The 1.50° wide demolding angle ensures smooth mold stripping and reliable SMT nozzle pickup. All dimensions strictly conform to EIA-481 global carrier tape specifications, compatible with all mainstream 12mm wide taping and placement machines.

Full Transparent Body for Zero-Waste Visual QC: Real-time inline inspection without tearing cover tape, greatly reduces packaging waste and labor cost for quality checking.
Non-Yellowing High-Clarity Virgin PC Raw Material: The transparent material stays clear and haze-free after months of stock storage, supporting continuous visual inspection.
Stable Mass Customization Support: Fast mold revision for different SMA variant body sizes, million-meter bulk order delivery with competitive pricing.
Application Scenarios
SMA small-body packaged diodes, rectifiers and discrete semiconductors
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 use a 2.45mm deep pocket for SMA small-body diodes?A: SMA diodes have a tall vertical body. Ordinary shallow pockets will press down on the top of the component and bend the fine pins. The deep cavity provides enough vertical clearance to fully hold the tall diode without compression damage.Q: What is the benefit of 0.22mm thick transparent PC compared with thinner clear substrate?A: Transparent PC has lower inherent rigidity than black PC. When wound with heavy tall diodes, thin clear tape will permanently curl after long stacking. The upgraded 0.22mm thickness strengthens the tape structure to keep it flat throughout production, logistics and storage.
