A 12-inch compatible wafer expander using a motor drive system. Support for up to 8 inches is also available.
The motor-driven expander is a device that uses an electric motor for the driving mechanism to raise the expansion stage. This device is a wafer expander that employs a motor-driven method with higher precision and excellent repeatability, and it is compatible with 12-inch wafers, known as the "EX-300." *Support for up to 8 inches is also available. The EX series "wafer expander" is a tape expansion device that stretches fully cut wafers along with the dicing tape on the expansion stage, allowing for uniform widening of chip spacing and street width to appropriate dimensions. By using a motor for the drive of the expansion stage, it enables numerical management of the expansion stroke and expansion speed. It also comes standard with an auto-cut function. Techno Vision offers various wafer expanders, including basic models, motor-driven expanders compatible with 12-inch wafers, and expanders with auto-cut functions, allowing for selection based on requirements. After expansion, the grip ring (automatically clamping the inner and outer rings) maintains the expanded state of the tape.
