Wafer Film Expander is an equipment, which is used to evenly stretch the tape after the cutting process, so as to separate the chip after cutting and evenly pull apart a certain distance. Adopt servo motor to expand film, the height and speed of expanding film can be set in the touch screen.

Wafer expander, also called UV Tape Expander Machine or Die Matrix Expander, is widely used in the grain expansion process of light-emitting diode, small and medium power transistor, backlight source, LED, integrated circuit and some special semiconductor devices. For example, in the LED industry, grain diffusers divide tightly packed LED wafers evenly, allowing them to be better implanted into welders. It takes advantage of the heating plasticity of LED film, adopts the control of double cylinder up and down, and spreads the single LED wafer evenly to the four sides. After reaching the satisfactory wafer gap, it is automatically formed, and the diaphragm is tight without deformation. The operation is sample and easy to understand.

Note to choose wafer expander: please provide crystal expanding ring size and the type of uv film.

The process of cutting semiconductor integrated circuit chips out of the wafer, the gap between the chips is very small, resulting in the chip collision, resulting in fragmentation, waste.

The wafer uv film expander can simply and quickly expand the cut chip in the X-Y direction, and the spacing between the chips is evenly increased to the required size, so as to separate the chip and avoid the collision damage between the chips, so as to obtain the intact integrated circuit chip. With heating and temperature adjustable table design, can make the film expanding effect better, and can greatly improve the height of film expanding, to meet the needs of different customers. The height of film expansion is adjustable. Wafer film expanding speed is adjustable. Table temperature is adjustable.

Application of Wafer Expansion System:

Wafer film expanding equipment is suitable for IC, Diode, Transistor, Glass, LED, QFN, PCB and other industries. It is suitable for the expansion or stretching process after cutting process in semiconductor integrated circuit chip manufacturing.

Wafer film expander series products are specially used for wafer, LED and other cutting film expansion process, equipped with imported guide rail, temperature control system, can evenly expand the spacing between grains.

Characteristics of Semi-automatic Die Matrix Expanding Machine:
