AI Overview

A semiconductor wafer expanding device is a precision tool used after dicing to stretch dicing tape, separating dies to prevent chipping during pick-and-place operations. These machines, available in manual, semi-automatic, and fully automatic types, use heated stages to expand the tape uniformly, optimizing chip spacing for automated handling in semiconductor and LED manufacturing.

Key Features and Capabilities:

Expansion Mechanism: Utilizes pneumatic or manual force to push an inner grip ring into an outer ring, stretching the film to create precise, uniform spacing between chips.
Heating Capabilities: Equipped with heated, thermostatically controlled stages to increase film flexibility, reducing the risk of tape tearing.
Wafer Size Capability: Accommodates various wafer sizes, typically ranging from 6-inch (150 mm) up to 12-inch (300 mm) wafers.
Automation Levels:
- Manual (e.g., ETM-150): Highly reliable for low-volume or varied production, offering high ergonomics and simple operation.
- Semi-Automatic: Automates the expansion and sometimes the cutting process, reducing human error.
- Fully Automatic: High-throughput systems with PLC control for fast, consistent results.
Common Applications: Widely used in packaging for LEDs, power transistors, and integrated circuits to improve yield and facilitate die bonding.
