1、 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.

1. 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.

2. Purpose:

After the cutting process of cutting the semiconductor integrated circuit chip from the wafer, the gap between the chip and the chip is very small, which will lead to the collision between the chip and the chip, resulting in edge collapse and waste.

The film expander can simply and quickly expand the cut chips in the X-Y direction, and the spacing between the chips can be uniformly increased to the required size, so as to separate the chips and avoid collision damage between the chips to obtain a complete integrated circuit chip. The workbench design with heating and adjustable temperature can make the film spreading effect better and greatly increase the film spreading height to meet different customer needs. The film spreading height is adjustable. The protective film speed is adjustable. The temperature of the workbench is adjustable.

3. Application fields:

Wafer film expanding equipment is applicable to IC, diode, transistor, glass, led, QFN, PCB and other industries, and is applicable to the expansion or stretching process after the cutting process in the semiconductor integrated circuit chip manufacturing. The wafer expander series products are specially used for the film expanding process after the cutting of wafers and LEDs. They are equipped with imported guide rails and temperature control systems, which can evenly expand the spacing between the grains. At present, the wafer expander models include: 6-inch film expander, 8-inch film expander, 10 inch film expander, 12 inch film expander, semi-automatic wafer film expander, manual film expander.
