Semi-Automatic Wafer Film Expanding Machine / Wafer Expander

Introduction:

Wafer expander is also called wafer expander or wafer expander. It is widely used in the grain expansion process in the production of light emitting diodes, small and medium power triodes, backlights, LEDs, integrated circuits and some special semiconductor devices.

For example, in the LED industry, the die expander evenly separates the compact LED wafers to better implant them into the welding workpiece. It makes use of the heating plasticity of LED film and adopts double cylinder up and down control to evenly diffuse a single LED wafer to the surrounding, and automatically form after reaching a satisfactory wafer gap, so that the film is tight and not deformed. Constant temperature design pottery plate, easy to understand.

Principle:

Wafer film expander is used to evenly stretch the film after the cutting process, so as to separate the chips after cutting and evenly pull apart a certain distance. The film spreading mode of servo motor is adopted, and the film spreading height and speed can be set parametrically in the configured touch screen. There are many names for wafer expander: wafer expander, led expander, led expander, grain expander, wafer expander, ring expander, plastic ring expander, wafer expander, wafer expander, 6-inch expander, 8-inch expander, 10 inch expander, 12 inch expander, semi-automatic wafer expander and manual expander.

Matters needing attention when selecting wafer expander: please provide the size of inner ring and outer ring of your wafer expander and the type of film you use.
