Stamp Bonding Donor Carrier|High-Stability
Alignment Carrier
Key Features:
• Delivers consistent tack value, ensuring precise chip alignment
without displacement or skew
• Suitable for thermal transfer processes in high-precision stamp
bonding
Application Scenarios:
• Stamp bonding during the COC2 phase
• Applications requiring high alignment accuracy using stamp
compression

Repair Donor Film|For Precision Rework
Processes
Key Features:
• Dedicated for COC2-phase rework; supports chip alignment and
transfer to blue tape or stamp platforms
• Enables accurate chip repositioning and rework, enhancing yield
control and material utilization
Application Scenarios:
• Post-transfer rework for COC2 uLED chips
• Precision chip replacement or selective reworking operations

B-stage Sheet Encapsulation Film|For micro/Mini LED & Semiconductor Packaging
Key Features:
High-reliability encapsulation solution
designed to enhance transfer accuracy and process stability.
Application Scenarios:
Chunyang provides B-stage thermosetting
encapsulation films engineered for micro/Mini LED mass transfer and advanced
semiconductor packaging. These pre-cured films feature controlled flowability,
adhesion stability, heat resistance, and low residue, making them ideal for
multi-layer stacking, chip attach, and wafer-level packaging (WLP). The films
help improve alignment accuracy and process consistency while reducing yield
loss.
